Fixing the Mistake: Limitation Periods in Professional Negligence Cases

Over a decade after Ontario’s Limitations Act, 2002 came into force, courts are still grappling with when a cause of action is discoverable and a limitation period starts to run. An increasingly litigated question relates to whether a limitation period runs while efforts are ongoing to fix the error that gave rise to the plaintiff’s claim. The Court of Appeal for Ontario recently addressed this issue in Presidential MSH Corp v Marr, Foster & Co LLP.

In contractual disputes, after-the-fact conduct is admissible after all

To most people, a contract is a written agreement, typically signed by all parties, that sets out what different parties promise to do. But what happens that the written agreement is ambiguous? Courts have long held that evidence of the “factual matrix” of the contract—that is, the surrounding circumstances that inform the context in which a contract is created—is admissible in the interpretation of a contract. In its recent decision in Shewchuk v Blackmont Capital Inc, the Ontario Court of Appeal confirmed that evidence of subsequent conduct may also be admissible to interpret the agreement itself.
