The Ontario Court of Appeal’s decision in Price v Smith & Wesson Corporation is a significant development in product liability law and class action procedure, particularly in cases involving harm from criminal acts. The ruling allows a class action in negligence to proceed against Smith & Wesson, the manufacturer of the handgun used in the 2018 Danforth Avenue mass shooting in Toronto.
June 26, 2025Amid ongoing tariffs and persistent economic uncertainty, Ontario has taken a significant legislative step with the passage of Bill 5, the Protect Ontario by Unleashing our Economy Act, 2025. Receiving royal assent on June 5, 2025, several provisions of the Act came into force immediately. Already prompting public debate, the impacts of Bill 5 are expected to be far reaching and significant for Ontario’s construction and infrastructure sectors.
June 12, 2025Here’s a look at the leave application decisions that the Supreme Court of Canada will be releasing on June 12, 2025.
June 12, 2025The Federal Court’s recent decision in Chief Derek Nepinak and Chief Bonny Lynn Acoose v His Majesty the King is a significant procedural decision that could have implications for many cases asserting Indigenous rights. The specific issue in this case was whether claims for the indexation of Treaty 4 annuity payments should proceed as a class action or as a representative proceeding. However, the case potentially has broader implications. The outcome clarifies the procedural path for collective treaty rights claims. More generally, this case highlights the multiple procedural vehicles available to assert group claims and demonstrates that class actions are not the only available tool.
June 9, 2025In light of concerns that unsubstantiated or misleading sustainability claims are eroding consumer trust, Canadian legislators took steps last year to increase oversight into environmental claims under the Competition Act.
June 9, 2025Lenczner Slaght is keeping a close eye on the latest news regarding the proposed civil justice reforms in Ontario. In the past month, the Civil Rules Review Working Group, alongside judges and lawyers with diverse practices, have presented their perspectives on the Phase 2 Consultation Paper. In this blog, we summarize the key takeaways from two significant presentations.
June 5, 2025Here’s a look at the leave application decisions that the Supreme Court of Canada will be releasing on June 5, 2025.
June 4, 2025Here’s a look at the leave application decisions that the Supreme Court of Canada will be releasing on May 29, 2025.
May 27, 2025Julien Sicco co-authored a blog on the importance of focused, sufficient and admissible evidence, as seen in the Supreme Court of British Columbia’s decisions in Bosco v Mentor Worldwide LLC and Ennis v Johnson & Johnson. (Prior to joining Lenczner Slaght)
May 22, 2025In North v Bayerische Motoren Werke AG, the Ontario Court of Appeal delivered a significant ruling on the boundaries of product liability in negligence. The decision confirms that negligence claims for pure economic loss in product liability cases can only succeed in narrow circumstances. For class action and product liability lawyers, the case serves as a reminder of the limits that govern certification in negligence-based claims.

The Court of Appeal recently issued a significant decision, Ontario (Health Insurance Plan) v KS, on funding for gender affirming care. The ruling provides clarity on access to insured gender affirming procedures while leaving some questions unresolved for future consideration.
April 25, 2025On April 10, 2025, Justice Boswell and Allison Speigel, the Co-Chairs of the Working Group responsible for preparing the Civil Rules Review, presented the Phase 2 Consultation Paper to The Advocates’ Society via Zoom. It was their first presentation to the bar at large following the release of the Consultation Paper on April 1, 2025. They advised that over 1,200 members of the Ontario bar had joined the Zoom presentation.
April 11, 2025The Working Group established by the Ontario Superior Court of Justice and the Ministry of the Attorney General has proposed significant reforms to the Rules of Civil Procedure in the Civil Rules Review Phase 2 Consultation Paper. The proposed changes are aimed at creating a more efficient and accessible civil justice system. Our overview of the proposed changes and key differences from the existing Rules can be found here.
April 10, 2025The Ontario Superior Court of Justice and the Ministry of the Attorney General have proposed significant reforms to the Rules of Civil Procedure in the Civil Rules Review Phase 2 Consultation Paper. The Working Group responsible for the Civil Rules Review is rethinking the system of civil litigation in Ontario “from the ground up” to ensure accessible and expeditious justice for all. Our overview of their proposed changes can be found here.

April 10, 2025If the Civil Rules Review Working Group’s proposals for reforms to the Rules of Civil Procedure (summarized here) are adopted, trial practice in Ontario will undergo significant changes. Key aspects of those proposed reforms include:
April 10, 2025Dramatic changes have been proposed for Ontario’s Rules of Civil Procedure. Whether the recommendations are adopted in whole or in part, in-house counsel teams should be thinking about steps that may be needed to ensure their business can transition seamlessly to a new litigation procedure. We have set out some considerations for in-house teams to help prepare for a smooth transition.
April 10, 2025President Donald Trump proclaimed April 2 “Liberation Day” and unveiled a new trade policy for worldwide “reciprocal tariffs”. Initial reactions were that Canada (and Mexico) emerged relatively better off in that they would continue to benefit from a 0% tariff on goods compliant with the United States-Mexico-Canada Agreement (USMCA). However, the scope of such exceptions is itself an uncertainty, as the USMCA is up for a review in 2026 and may well be renegotiated sooner than that. In the meantime, Canada still faces the 25% tariff on steel and aluminum which came into effect on March 12, and most importantly a 25% tariff on automobiles and auto parts which comes into effect today.
April 3, 2025On April 1, 2025, various amendments to the Trademarks Act and Trademarks Regulations will come into force. The overarching theme of the upcoming amendments is to increase efficiency and effectiveness in trademark proceedings before the Trademarks Opposition Board (TMOB) and the Federal Court.
March 31, 2025In Benchwood Builders Inc v Prescott, the Court of Appeal for Ontario provided further guidance on the interpretation of section 137.1 of the Courts of Justice Act, commonly known as anti-SLAPP legislation. This legislation provides a quick screening mechanism to dismiss lawsuits that unduly limit expressions related to a matter of public interest – often referred to as Strategic Lawsuits Against Public Participation (SLAPP).
March 17, 2025-
In its recent judgment in 2730453 Ontario Inc v 2380673 Ontario Inc, the Ontario Court of Appeal upheld the trial decision of the Honourable Justice Centa, which awarded specific performance to the Purchaser (successfully represented by Lenczner Slaght) for the Vendor’s breach of an oral agreement for the purchase and sale of a 32-acre parcel of land for development. In doing so, the Court clarified the legal requirement that a prospective purchaser must prove “detrimental reliance” in undertaking acts of part performance before an oral agreement will be enforced in the face of the Statute of Frauds.
March 14, 2025Since it was recognized a little over a decade ago in Bhasin v Hrynew, the contours of the organizing principle of good faith and the duty of honest performance in contract law have been gradually clarified by Canadian courts. Most recently, in Ocean Pacific Hotels Ltd v Lee, the British Columbia Court of Appeal considered whether the duty of good faith applied to pre-contractual conduct. In particular, the question in this case was whether an employer’s conduct before an employment agreement was finalized could be scrutinized under the duty of honest performance. Answering that question with a resounding no, the Court of Appeal’s decision provides critical insight into the evolving boundaries of good faith obligations in Canadian contract law.
March 6, 2025On December 2, 2024 a Delaware judge upheld her prior January 2024 ruling that Elon Musk’s compensation package, valued at $55.8 billion, had to be rescinded because it was approved in breach of the directors’ fiduciary duties (Tornetta v Musk). One month later, the same Delaware judge approved a settlement wherein Tesla’s directors agreed to return or forgo $919 million in compensation, which had been subject to a separate legal complaint by the Police and Fire Retirement System of the City of Detroit (Police & Fire Retirement System of the City of Detroit v Musk). The two cases were brought as derivative actions on behalf of shareholders of Tesla. The former action is now subject to an appeal brought by Tesla, but also an appeal by a separate group of Florida shareholders.
February 24, 2025The U.S. Copyright Office released a comprehensive report titled "Copyright and Artificial Intelligence Part 2: Copyrightability" (“U.S. Copyrightability Report”) in January 2025, which delves into the complex issue of copyright protection for AI-generated material.
February 3, 2025Following on Health Canada’s plan to introduce new regulations aimed at addressing therapeutic product shortages as discussed previously in our Fall Regulatory Roundup, proposed amendments to the Food and Drug Regulations and Medical Device Regulations were published for public comment on December 28, 2024. The comment period closes on March 8, 2025.
January 29, 2025Engaging Canada’s Patented Medicines (Notice of Compliance) Regulations (the “Regulations”) requires pharmaceutical patentees to first submit a list to Health Canada of patents to be included on the register – Canada’s equivalent to the Orange Book. Any delay in submitting that list after an eligible patent has been issued can have severe consequences on the scope of a patentee’s protections under the Regulations. The recent Federal Court decision in Serono v Canada (Health) is illustrative.
January 16, 2025Our readers know that we maintain a database that includes information relating to every Supreme Court of Canada leave decision from January 1, 2018 onward. While we use that database to maintain a machine learning model to predict the likelihood of particular cases getting leave to appeal, we also use it to look at trends at the Court more generally. In this blog post, we provide a year in review of the Supreme Court of Canada’s leave application decisions in 2024.
January 10, 2025In Barbiero v Pollack, the Ontario Court of Appeal has departed from Langenecker v Sauve and changed the law of dismissal for delay under Rule 24.01. Where a delay is found to be both inordinate and inexcusable, that alone is sufficient to dismiss the action. Plaintiffs can no longer allow an action to languish for years and then rebut the presumption of prejudice to keep it alive.
December 23, 2024Nicole Naglie & Madison MacKinnonIn Bertsch v Datastealth Inc, the Superior Court confirmed the enforceability of an ESA-minimum termination clause that excluded common law notice periods. This decision, resulting from a Rule 21 motion to strike, marks a welcome shift for employers in the court’s longstanding reluctance to uphold termination provisions in employment contracts.
December 10, 2024The Federal Court of Appeal’s decision in Galderma Canada Inc v Canada (Attorney General) (“Galderma FCA”) arose from what seemed like a straightforward production order, but ended up providing clear guidance on the jurisdiction of Canada’s Patent Medicine Prices Review Board (PMPRB). The key takeaway: the PMPRB’s jurisdiction extends only to patented medicines, not all medicines.

The Court of Appeal for Ontario (“ONCA”) will hear the appeal of Dufault v The Corporation of the Township of Ignace (“Dufault”) this Friday. While Ontario courts previously recognized that creating jurisprudence based on hypothetical situations is a slippery slope, since the decision in Waksdale v Swegon North America Inc, courts in Ontario have repeatedly invalidated termination clauses in employment agreements by considering hypothetical breaches of employment standards legislation.
December 5, 2024Jordana Sanft & Natalie WorkewychIn the recent decision in Bayer Inc v Amgen Canada Inc, Case Management Judge Duchesne of the Federal Court dismissed a request for samples on the basis that Bayer failed to demonstrate that the proposed testing could lead to a result that would assist the trial judge in determining an issue in the proceeding.
December 2, 2024Canada’s federal structure means national class actions naturally raise potential constitutional questions. Those questions become potentially more thorny where a class action is pursued not on behalf of individuals across multiple provinces and territories, but instead provincial and territorial governments themselves. The Supreme Court’s recent decision in Sanis Health Inc v British Columbia addressed many of those concerns and ultimately defined a broad scope for national class proceedings, including where a proposed class includes other provincial or territorial governments.

November 22, 2024When we think about the broad direction of government policy, we generally think about the statutes introduced by the legislature. However, the reality is that much of the laws that impact us are subordinate legislation: regulations, rules, and policies that are enacted by Ministers, boards and agencies, or other government actors pursuant to rule-making power provided to them under legislation. For nearly a decade, challenges to subordinate legislation were extremely challenging. The Supreme Court of Canada’s 2013 decision in Katz Group Canada Inc v Ontario (Health and Long‑Term Care) set a high bar for challenging such subordinate legislation. The Court in that case held subordinate legislation “must be ‘irrelevant’, ‘extraneous’ or ‘completely unrelated’ to the statutory purpose to be found to be ultra vires on the basis of inconsistency with statutory purpose.”

November 7, 2024Andrew Moeser & Alexis VaughanAs part of our series on summary proceedings in IP cases, we previously commented on the Federal Court of Appeal’s guidance on when and how a court should determine if summary trial is appropriate. In this post, we consider Associate Judge Horne’s recent decision in Toronto-Dominion Bank v Dyas (“TD Bank”), which deals with when a Case Management Judge should schedule (or refuse to schedule) a summary trial.
November 1, 2024Julien Sicco co-authored a blog on Health Canada’s recent changes to the manner in which medical devices and pharmaceutical products are recalled under the Medical Device Regulations and the Food and Drug Regulations, summarizing the significant legislative amendments. (Prior to joining Lenczner Slaght)
October 29, 2024The recent decision in Munchkin Inc v Angelcare Canada Inc presents an example of circumstances in which foreign parent companies can be held liable for patent infringement in Canada.

The proceedings in Canada (Privacy Commissioner) v Facebook Inc arose from the Privacy Commissioner’s investigation into Facebook’s practice of sharing users’ personal information with third-party apps. At the Federal Court, Justice Manson dismissed the Commissioner’s application, finding that the Commissioner had not shown that Facebook failed to obtain meaningful consent from users to disclose their data, and had not shown that Facebook failed to adequately safeguard user data. In its latest decision, Justice Rennie of the Federal Court of Appeal allowed the Commissioner’s appeal, concluding that Facebook indeed breached Personal Information Protection and Electronic Documents Act (PIPEDA)’s requirement to obtain meaningful consent from users prior to data disclosure and its obligation to safeguard user data.
October 17, 2024As important as corporations are to modern commerce, Courts have long struggled with how to make these fictional persons responsible for their actions when allegations against them require the Court to assess their state of mind. The problem is as old as the modern corporation, and can cause exasperation when corporations fail, leading Lord Chancellor Thurlow in the 18th century to remark that a corporation, being a fiction, “has neither a body to kick, nor soul to be damned.”
October 16, 2024Fall Regulatory Round Up
Activity abounds on the regulatory landscape from modernization and transparency initiatives to consultations, collaborations, and even potential implementations. Our Fall Regulatory Round Up highlights significant developments for drug products and patents that are of interest to those in the life sciences and biotech spaces. We will be following these important regulatory initiatives as they continue to unfold and will provide updates of interest.
September 30, 2024In its recent decision, Mud Engineering Inc v Secure Energy Services Inc, a divided Federal Court of Appeal considered the effect of the parties’ failure to prove ownership in the context of a summary trial. Though both the majority and the dissenting opinions agreed that the Patent Act creates a rebuttable presumption of ownership, they differed on which party should bear the burden of proving ownership once that presumption has been successfully rebutted and on the effect of that rebuttal on the underlying infringement action.
September 9, 2024Christine Windsor & Mina AlamIn Poonian v British Columbia (Securities Commission), a majority of the Supreme Court of Canada clarified provisions in the Bankruptcy and Insolvency Act (the “BIA”) that govern when a bankrupt is not released from a claim upon an order of discharge. The Supreme Court concluded that while bankruptcy may release bankrupts from administrative penalties, it will not release them from orders to pay amounts obtained by fraud.
August 8, 2024In March 2024, The Body Shop Canada (“TBS Canada”) filed a Notice of Intention to make a Proposal under the Bankruptcy and Insolvency Act after its UK parent company completed a cash sweep of TBS Canada. The cash sweep instantly eliminated TBS Canada’s liquidity, forcing it to suspend online orders and close 33 retail stores.
July 26, 2024The intersection of artificial intelligence and intellectual property law is once again in the spotlight with the latest legal proceeding, Samuelson-Glushko Canadian Internet Policy and Public Interest Clinic v Ankit Sahni.
July 18, 2024In the final instalment of our AI in the Courtroom series, we explore practical challenges that may arise when litigating in an AI world, and within the current framework of the Rules of Civil Procedure, Practice Directions, and common law. While the law is not entirely unequipped to deal with these challenges, evolution in the Rules and common law will likely be necessary as AI becomes more commonly used by various participants in the litigation process.
June 24, 2024Savvy content creators and copyright owners often use technical protection measures (also known as “TPMs”) to restrict what users can do with their works (often digital materials). The prohibition against circumventing TPMs is rooted in sections 41 and 41.1 of the Copyright Act, but their fit within the broader Copyright Act is the subject of ongoing debate.

As widely reported by the likes of CBC, the Guardian, the Verge and CNBC, OpenAI has indicated they will “pause” the use of their AI-generated voice after users (and Scarlett Johansson herself) noted the striking similarity to Scarlett Johansson's voice from the film “Her”. This connection may have been intentional, OpenAI’s CEO, Sam Altman, posted a one-word message – “her” – on his social media on the day the AI-generated voice was unveiled.
May 24, 2024In our last comment on non-patentable subject matter, we provided our thoughts on the Federal Court of Appeal’s decision in Canada (Attorney General) v Benjamin Moore & Co (the “Benjamin Moore Appeal”). As a top line, this decision was a loss for Canadian innovation. As we discussed in detail, the Federal Court of Appeal missed an opportunity to clarify the law of patentable subject matter, adopt the IPIC framework endorsed by Associate Chief Justice Gagné, and signal to the Canadian Intellectual Property Office (“CIPO”) that its examination practices were out of step with the law. Instead, the Federal Court of Appeal further complicated an already complex area of the law, which will increase the costs of innovators to register their technologies in Canada.
May 22, 2024As artificial intelligence continues to permeate every aspect of our lives, legal challenges involving AI will proliferate. Parts 1 to 3 in our series explored many of these potential questions. AI will create new legal problems and change the texture of old ones. As always, the judiciary, with the assistance of counsel, will assume a pivotal role in navigating this landscape.
May 22, 2024A desire to expedite patent disputes may result in a party pursuing summary adjudication. We have previously commented on a number of cases relating to the use of summary proceedings for resolving patent cases in Canada. In particular, in the Federal Court of Appeal’s 2022 decision in Gemak Trust v Jempak Corporation, the FCA held that summary judgment is not appropriate where there are serious issues with respect to the credibility of witnesses, and the Court observed more generally that “while patent infringement issues are not by definition excluded from the ambit of the summary judgment process, they tend to raise complex issues of fact and law that are usually better left for trial”. We noted that in Gemak, the FCA was tapping the brakes on a trend towards increased adoption of summary proceedings in patent cases, and that for parties interested in summary adjudication, summary trial may be a more attractive option, particularly where witness credibility, and especially expert credibility, is likely to be an issue.
May 15, 2024The multifaceted nature of generative AI is bound to create legal complexities at the intersection of intellectual property law and class actions, as this emerging technology disrupts not only the tech landscape but the legal one too.
May 6, 2024The Federal Court of Appeal’s decision in Steelhead v ARC upholds Justice Manson’s summary trial decision finding no infringement by ARC Resources of Steelhead’s 085 Patent. In summary, the FCA held that the marketing of an apparatus that – if built – would infringe the 085 Patent did not constitute “use” (or “exploiter” in the French version) under section 42 of the Patent Act, and therefore could not be infringement.
April 29, 2024Barring a very narrow set of circumstances, sophisticated parties with equal bargaining power are generally held to the terms of their agreement. 660 Sunningdale GP Inc v First Source Mortgage Corporation is a recent example where a commercial developer, 660 Sunningdale GP, was ordered to pay the entirety of the lender fee to the lender, First Source Mortgage Corporation, even though the loan did not proceed.

April 23, 2024Did Drake respond to an alleged feud with fellow artists, including Kendrick Lamar and Rick Ross? As reported by the LA Times, a track titled ‘Push Ups (Drop and Give Me 50)’ appeared online recently, taking aim at Lamar and several of his recent musical collaborators. However, this track remained unclaimed on any of Drake’s official platforms, causing some to question whether this track was fan-generated using artificial intelligence. This cynicism may be justified: Drake is reportedly no stranger to having to denounce fan-generated songs, and Lamar’s rumoured response was actually the work of artificial intelligence and another rapper.
April 22, 2024The current landscape is inundated with narratives surrounding artificial intelligence and its intersection with the law. From the New York Time’s lawsuit launched against OpenAI in December 2023, to the BC lawyer reprimanded for citing fake AI-generated cases, to the lying Air Canada chatbot, the legal and mainstream media is full of stories of AI or people using AI running up against traditional legal doctrine and practice. Yet, amidst this surge of AI-related incidents, Canada finds itself grappling with more questions than answers.
April 18, 2024-
In two decisions released on the same day, the Federal Court has confirmed that applications are summary procedures that exclude the right or ability to examine witnesses who have not sworn affidavits.
April 15, 2024In Canada, a generic pharmaceutical company can commence an action for damages under section 8 of the Patented Medicines (Notice of Compliance) Regulations (the “Regulations”), if it successfully defends a patentee’s claims in an earlier section 6 prohibition proceeding. Section 8 actions are often complex, requiring a determination of the alleged loss suffered by assessing a “but-for world” where the generic would have received regulatory approval and commenced sales at an earlier date, but for having been blocked by the operation of the Regulations. Depending on the drug(s) and patent(s) at issue, there may be several independent section 8 actions against a patentee, each started by a different generic plaintiff (see our previous post). When distinct section 8 actions are commenced pertaining to the same drug(s), patent(s), and patentee(s), issues as to relevance and scope of each action may arise.
April 12, 2024The proposed reforms to Ontario's Rules of Civil Procedure (which we summarize here) includes innovative ways to better harness technology, making the litigation process quicker, simpler, and more accessible. The ongoing Civil Rules Review Working Group has proposed several enhancements to build on the steps our courts have taken since the pandemic, using more electronic means for filings, hearings, and civil litigation overall. These proposed changes aim to streamline legal processes and improve access to justice through the effective use of technology.
April 10, 2024By playing their essential gatekeeping role, class action judges have in numerous decisions clarified the necessary elements of various causes of action and the availability of specific remedies in a particular case. What constitutes harm that is compensable, for example, has featured in numerous product liability class actions and the failure to show harm has put an end to many of them. For strategic and practical reasons, some class actions do not seek compensation for losses that the class members suffered. Instead, the strategy is to pursue remedies that do not correspond with personal losses such as disgorgement, nominal damages and punitive damages. Hoy v Expedia Group Inc is a recent example.
April 9, 2024A power of sale is a very common mortgage remedy used by lenders where a borrower defaults under the applicable mortgage agreement. In light of the current interest rate environment, the power of sale process has anecdotally been exercised more frequently. Lenders (and borrowers), however, should keep in mind when such a right can be restrained.
April 3, 2024In the recent decision of Wyse Meter Solutions Inc v CARMA Corp, Justice Audrey P. Ramsay rejected an attempt by a former employer to obtain injunctive relief enforcing a non-competition clause against an employee who had been required, as a condition of employment, to purchase shares in the employer.
March 18, 2024In Canada, numerous class proceedings have launched on behalf of governments and individuals against entities involved in the manufacture and distribution of opioids. These actions claim wrongful acts and damages that extend over 23 years, raising important legal questions for the insurers of these entities as to the extent of their obligation to defend the proceedings on behalf of their insureds.
March 7, 2024Court orders must be obeyed. If they are not, the consequences can be severe.
March 6, 2024Few pop icons have navigated the art of protecting their intellectual property as well as Taylor Swift. Not only does Taylor Swift have an outstanding knack for creating number one hits, a keen eye for branding, and an entrepreneurial spirit that is inspiring, she is also business savvy in protecting her trademarks and copyright. On this International Women’s Day 2024 we look to Taylor Swift as an inspiration in IP protection, enforcement, and commercialization, as we celebrate women who “could show you incredible things”.
March 6, 2024If your 2024 has been too busy to keep up with caselaw, below we summarize and provide the key takeaways from pharmaceutical patent decisions that have been issued from the Federal Court and Federal Court of Appeal in the last two months.

Matthew Sammon & David Salter
After a three-week trial, the Ontario Superior Court has held that the Royal Bank of Canada had after-acquired cause to terminate a senior banker, Aidan Mittra, and dismissed Mittra’s $10‑million lawsuit.
February 21, 2024On February 14, 2024, the British Columbia Civil Resolution Tribunal (which is the equivalent of Ontario’s Small Claims Court) issued its decision in Moffatt v Air Canada. In less than a week, the decision has made international news as a result of the involvement of Air Canada’s chatbot.
February 21, 2024It has been approximately six months since the Federal Court of Appeal’s decision in Canada (Attorney General) v Benjamin Moore & Co (the “Benjamin Moore Appeal”) was released, yet no practice direction has been issued from the Canadian Intellectual Property Office (“CIPO”) to address the decision, and there is no consistency in the way that computer-implemented inventions are being examined. As the patent bar awaits a decision on the leave application to the Supreme Court of Canada, we provide our thoughts on the Federal Court of Appeal’s decision, and the missed opportunity it was.
February 16, 2024In 2020, following a series of recommendations released by the Law Commission of Ontario, the Ontario legislature passed substantial amendments to the Class Proceedings Act. Many of those amendments were drawn straight from the Law Commission’s report and were generally supported by most stakeholders.
January 19, 2024Our readers know that we maintain a database that includes information relating to every Supreme Court of Canada leave decision from January 1, 2018 onward. While we use that database to maintain a machine learning model to predict the likelihood of particular cases getting leave to appeal, we also use it to look at trends at the Court more generally. In this blog post, we provide a year in review of the Supreme Court of Canada’s leave application decisions in 2023.
January 15, 2024Lynne McArdle published the first issue of On the Docket: Cases to Watch, which features a collection of cases that move the law forward in some meaningful way. The cases in this edition are diverse in that they arise in different areas of the law: fraudulent conveyances, securities law, class actions, employment law, discovery, and Crown law.
December 22, 2023Recent years have seen a wave of reforms to the Competition Act being discussed and implemented. That wave has become a veritable tsunami with omnibus legislation introduced in Parliament in November 2023. That legislation proposes a number of fundamental changes to the Competition Act, which have the potential to dramatically impact Canadian businesses. While a detailed discussion of all of the amendments is beyond the scope of this blog post, perhaps the most interesting thing to litigators and businesses concerned about litigation risk, is the creation of what may prove to be a kind of pseudo-class action regime before the Competition Tribunal that ultimately allows consumers to recover losses as a result of certain types of reviewable conduct.
December 8, 2023Pleadings continue to be a popular battleground in the product liability context. Over the years, a body of law has developed respecting motions to strike for negligent design, negligent manufacture and failure to warn claims. Nevertheless, there continues to be debate as to the specificity needed for pleading these types of claims. That debate is fuelled in part by jurisprudence demonstrating a high tolerance for claims that are arguably vague and lacking in material facts. Even where a claim is struck, plaintiffs are routinely permitted to amend their pleading.
November 17, 2023On November 10, 2023, when the Supreme Court of Canada (“SCC”) released their decision in R v Greater Sudbury (City), the internet responded with widespread panic because, for the first time, the Court has confirmed that a project owner is an employer under Ontario’s Occupational Health and Safety Act (“OHSA” or the “Act”).
November 15, 2023A recent decision of the Ontario Court of Appeal illustrates how the doctrine of repudiation of contracts applies to buy-sell agreements. The Court found that a contract created under a buy-sell mechanism can be repudiated where one party's conduct undermines the integrity of the valuation machinery of the buy-sell.
November 14, 2023-
The complexity of regulating environmental impacts in Canada has proven to be a thorny issue on both constitutional and practical fronts. On the heels of 2021’s carbon pricing decision, the Supreme Court of Canada has again weighed in on how the division of powers can impact environmental regulation. This time, the Court considered the federal environmental assessment regime, ultimately finding that the federal legislation waded too far into provincial waters.
November 2, 2023Commercial disputes between professionals and their clients are routine. However, what is comparatively rare are disputes between the consultants (or other professionals) who advise a client and the client’s customers who may be harmed in some way by that client’s conduct. In those circumstances, there is generally no contractual relationship between the consultant and the client’s customer, and most cases have held that there is no duty of care between a professional and a person injured by the professionals’ client’s conduct. Lawyers, for example, have been held to potentially owe duties of care to non-clients in only the most exceptional circumstances. However, the recent decision of the British Columbia Supreme Court in British Columbia v McKinsey has the potential to substantially expand the scope of claims brought against professionals by persons allegedly harmed by those professionals’ clients’ conduct.
October 20, 2023On August 25, 2023, Canadians were advised that KLEENEX was blowing out of town and would no longer be available in Canada (see Globe & Mail article).
August 30, 2023The “Creativity Machine”, owned by Stephen Thaler, generated a work of art of its own accord. Thaler applied to register copyright in the artistic work titled ‘A Recent Entrance to Paradise’ with the United States Copyright Office. The application stated the Creativity Machine created the work and it was listed as the author. Thaler sought to transfer the copyright to himself as owner. The registration was denied.
August 22, 2023This blog post deals with two areas of law that are near and dear to my heart: class actions and appeals to the Supreme Court of Canada. The question I tackle in this post is whether class actions are more likely than other types of cases to be granted leave to appeal to the Supreme Court of Canada.
July 20, 2023Andrew Moeser will be sharing his expertise on patent enforcement at the joint Intellectual Property Institute of Canada and McGill University Summer IP Course. Andrew will lead a discussion on Patent Enforement: Infringement, as well as participate on a Mock Trial focused on Expert Reports and Cross-Examination of a Witness.
July 18, 2023In the recently released decision Boehringer Ingelheim Ltd v Jamp Pharma Corporation, Jamp brought a motion seeking an order that would require Boehringer to make their employee inventors attend to be examined for discovery, failing which the order could be enforced against Boehringer themselves. Boehringer argued that the Rules do not contemplate such an order. Associate Judge Duchesne agreed.

In the recently released decision dTechs EPM Ltd v British Columbia Hydro and Power Authority and Awesense Wireless Inc, the Federal Court of Appeal (“FCA”) weighed in on the role and independence of experts in patent cases. In particular, the FCA provided guidance on (1) the role counsel may play in preparing expert reports; (2) an expert’s role in claim construction; and (3) the difference in the role of an expert where anticipation is alleged based on prior use versus prior publication.
May 31, 2023The philosopher Heraclitus observed that “the only constant in life is change”, a maxim as true for the business world as the natural world. Publicly traded companies operate in a dynamic environment, where commodity prices swing, new laws are passed, and scientific breakthroughs are made. So long as those companies wish to maintain their access to public markets, they must carefully consider how day-to-day happenings (and their own reactions to those events) affect their continuous disclosure obligations. These disclosure judgements are fact-specific and often fast-paced, yet they carry potentially significant consequences.
May 29, 2023Jonathan Chen & Caroline H. HumphreyA few years after the Supreme Court of Canada released Hollick v Toronto (City), which provided a detailed articulation of the common issues requirement under s. 5(1)(c) of the Class Proceedings Act, 1992, Ciara released her chart-topping single, “1, 2 Step”. While we would not go so far as to say that her single was one of the most succinct summaries of the common issues test from the early 2000s, she may have been on to something.
May 5, 2023Patent infringement cases are complex and technical, and historically Canadian courts were reluctant to endorse summary disposition in the patent context. However, in recent years there has been an increased trend towards the application of summary proceedings in this area. In particular, we have previously commented on decisions of the Federal Court (“FC”) (Canmar, Kobold, and Janssen) and Federal Court of Appeal (“FCA”) (Canmar and ViiV) that demonstrate the Court’s willingness to approve summary proceedings in patent cases under the appropriate circumstances. Last fall, the FCA decision in Gemak was interpreted by some commentators as a return to the historical position, but in our view, Gemak can be viewed as tapping the brakes on summary judgment rather than signalling a more sweeping reversal of the trend towards summary adjudication.
May 4, 2023Indirect infringement or “inducement” often arises in pharmaceutical patent infringement cases where a defendant generic manufacturer may not ultimately “use” the drug in question (i.e., directly infringe). Since 2011, the Federal Court of Appeal’s (“FCA”) Corlac Inc v Weatherford Canada Inc decision has frequently been cited as the leading authority for the tripartate test for inducement. In 2020, the Federal Court suggested that Corlac had changed the law of inducement—particularly at the second step determining influence—thereby requiring “a higher threshold for establishing inducement than was applied in the earlier cases”. In the recent decision of Teva Canada Limited v Janssen Inc (“Paliperidone”), the FCA has rejected that interpretation of Corlac. The FCA held that Corlac incorporates the same principles of inducing infringement as had been established in cases dating back to 1906. In doing so, it overturned the lower Court’s inducement determination based on a supposed higher standard and found that the defendant was liable for inducement when the Corlac test was properly applied.
April 13, 2023The use of generative artificial intelligence (AI) is on the rise and is receiving significant attention across disciplines and industries. The impact of generative AI spans various fields such as healthcare, gaming, education, marketing, visual arts, literature, music, banking and fashion, to name few. In the context of intellectual property law, where the focus is on innovation and creativity, generative AI raises countless complex questions. This blog post focuses on ChatGPT and copyright.
March 1, 2023Andrew Porter & Sean LewisShareholder agreements commonly contain buy/sell provisions establishing a process by which a shareholder can initiate a sale of their interest or can acquire the interest of another shareholder. The particulars of this process vary. Based on the parties’ bargain at the time the agreement is made, there are frequently unique and particular requirements to these provisions. The Ontario Superior Court of Justice emphasizes the importance of abiding by those requirements, as seen in a recent decision invalidating a purported closing of a share purchase transaction for the purchasers’ failure to comply with the specific process set out in the Shareholders’ Agreement. Justice Vella’s reasons in Leeder Automotive Inc v Warwick therefore offer an excellent reminder to shareholders that they disregard the requirements of a buy/sell provision at their peril.
February 10, 2023In a recent decision, Takeda Canada Inc v Apotex Inc, the Federal Court dismissed the Plaintiff, Takeda’s, motion for consolidation of two actions against Apotex relating to Takeda’s dexlansoprazole (DEXILANT) under section 6 of the Patented Medicines (Notice of Compliance) Regulations (the “PM(NOC) Regulations”).
January 30, 2023As many readers of our blogs know, we maintain a database that contains a wealth of information about every Supreme Court of Canada leave application decided from January 1, 2018 onward. That dataset allows us to provide a range of analysis and predictions relating to Supreme Court leave applications. But there is one fact that is apparent to all Supreme Court watchers that you don’t need a rich dataset to know: far fewer cases than usual got leave to appeal to the Supreme Court in 2022. The question this blog post tries to answer is: why?
January 20, 2023Last Friday, the Ontario Court of Appeal released decisions in Owsianik v Equifax Canada Co, Obodo v Trans Union of Canada, Inc, and Winder v Marriott International, Inc—a trilogy of decisions clarifying whether the tort of intrusion upon seclusion applies to the owners of databases when there are data breaches caused by third party hackers. Thankfully for database owners, the Court of Appeal concluded that intrusion upon seclusion cannot apply in those circumstances.

In a recent decision, Hummel Properties Inc v Niagara-on-the-Lake (Town), the Ontario Court of Appeal affirmed that the Town of Niagara-on-the-Lake’s enactment of an interim control by-law (“ICBL”) was illegal. The decision, summarized below, has important implications for municipalities, developers, and builders across Ontario.
November 8, 2022Some things just go better together and probably always will, as Luke Combs sings in ‘Better Together’. Like a cup of coffee and a sunrise; Sunday drives and time to kill. Multiple section 8 actions however have not made the cut. According to the recent decision of Justice Southcott in Apotex Inc v Janssen Inc, multiple actions for section 8 damages should not have common issues heard together.
November 3, 2022Class actions are strange creatures, even to other lawyers.
October 28, 2022Jonathan Chen & Angela HouHistory has shown that recalls for product defects are often followed by a proposed class action lawsuit. While many products cases in that context have been certified, we have now seen certification of proposed class actions being denied on the basis that there is already an effective recall campaign in place. We have seen this in Maginnis and Magnaye v FCA Canada et al and Richardson v Samsung.
October 12, 2022It is often said that the Class Proceedings Act, 1992 is a procedural statute, not a substantive statute. What that means in practice is unclear, given that different procedural rules can have an impact on substantive outcomes. However, even a narrow version of that claim—that the Class Proceedings Act does not grant the Court jurisdiction to create or extinguish substantive rights beyond what the Court could do in an individual claim—is very much up for debate. There are increasing examples of creative judges using provisions under the Class Proceedings Act to take steps that impact substantive rights in a manner that would be impossible in an individual claim. The Court’s recent decision in Cavanaugh v Grenville Christian College presents such an example.
October 6, 2022Over the last several years there has been a trend towards increased adoption of summary proceedings for resolving patent cases in Canada. In particular, we have previously commented on decisions of the Federal Court (e.g., Kobold partial SJ motion) and Federal Court of Appeal (e.g., Canmar Appeal) that signalled a willingness to move away from the historic reluctance of those courts to approve summary judgment for patent infringement actions. We had also noted that summary proceedings were a trend to watch this year.
September 8, 2022It has been just under a year since the new dismissal for delay provision in s. 29.1 of the Class Proceedings Act started resulting in dismissals for delay. In essentially all of the decisions rendered to date, judges have strictly construed those provisions to require the dismissal of matters where the statutory criteria for avoiding a dismissal are not present. The recent decision of the Ontario Superior Court in Lubus v Wayland Group Corp is now an outlier that takes a different approach.
August 24, 2022The Patented Medicines (Notice of Compliance) Regulations (PMNOC Regulations ) is a complete code. In Apotex Inc v Eli Lilly Canada Inc, the Ontario Court of Appeal weighs in on the drawn-out battle between patent owners and generics on whether monetary relief is available outside the parameters of the PMNOC regime. It is not.
August 19, 2022Jordana Sanft & Kaitlin SoyeIn FibroGen, Inc v Akebia Therapeutics, Inc, the Federal Court of Appeal set aside an order requiring a party to make certain fact witness statements from a discontinued action public, restoring the proper balance and safeguarding the confidentiality of documents that had been designated as confidential or highly confidential information.
August 10, 2022The Court of Appeal for Ontario has once again reaffirmed the deference afforded to first instance judges in cases of contractual interpretation that rely heavily on the factual matrix—even where the underlying facts and history are unique.

Employment law misclassification class actions are becoming increasingly common. In those cases, the plaintiff says that employees have been misclassified by their employer in such a way as to render them ineligible for certain benefits under applicable provincial employment standards legislation which the employee claims that they should have been eligible for. The two most common categories of alleged misclassification are employees being allegedly misclassified as independent contractors, and ordinary employees being misclassified as managers. While some misclassification cases have been certified, courts have refused to certify many others due to a lack of sufficient commonality. The recent decision of the Ontario Superior Court of Justice in Le Feuvre v Enterprise Rent-A-Car Canada Company is an example of a case that falls into the latter category and was not certified.
July 26, 2022Last week, the Supreme Court of Canada released its decision in SOCAN and Music Publishers of Canada v ESA, the latest instalment in a decade long battle about whether and how copyright owners should be compensated for making works available online (even if those works are not subsequently downloaded or streamed by a user).
July 21, 2022Madison Robins & Caroline H. HumphreyThe Supreme Court of Canada’s decision today in Law Society of Saskatchewan v Abrametz is a significant one for all lawyers practicing before administrative tribunals. In brief, the decision confirms that the three-part Blencoe test for delay and abuse of process in administrative proceedings continues in force. To establish that a delay rises to the level of abuse of process, a party must establish...
July 8, 2022Associate Chief Justice Gagné’s decision in Benjamin Moore & Co v Attorney General of Canada, 2022 FC 923 (“Benjamin Moore”) marks the second time that the Federal Court has had to weigh in to tell the Commissioner that it was not applying the correct test for patentability of computer-implemented inventions. Unlike past decisions (discussed below), the Court in Benjamin Moore, provided instruction on how the Commissioner ought to assess patentability of such inventions. As a top line, these instructions appear to level the playing field – reducing the artificially high standard that computer-implemented inventions face during patent examination.

June 28, 2022Summary adjudication can be enticing. In the right circumstances, it saves the parties time and money. Unsurprisingly, there is a growing trend in Canadian intellectual property litigation to use summary adjudication that we have been actively monitoring (see, e.g., our comments here, here, here, here, here and here).
