Legal 500 had this to say about our expert litigators:

Boutique firm Lenczner Slaght has a strong commercial disputes offering and routinely represent clients before all levels of court. The group is regularly instructed by multinational companies, individuals, small businesses and professional regulators. Practice co-head Monique Jilesen specializes in class action, contract and shareholder disputes, civil fraud cases, securities litigation and professional liability matters. Leading alongside her, Eli Lederman, frequently acts for company directors in litigation and advises on corporate governance matters. Complex cross-border litigation specialist Peter Griffin KC is another standout name, while Tom Curry handles class action, arbitration and business disputes. Matthew Lerner and Brian Kolenda also major on commercial litigation.

As a specialist litigation boutique, Lenczner Slaght packs a punch in contentious insurance work, where it handles a significant volume of policy, coverage and defence disputes. Frequently involved in challenging, high-profile cases, where it can bring its unique dispute resolution platform to bear, the group’s experience covers class action defence, D&O, product liability, and environmental and property damage claims, among other areas. Group head Nina Bombier is particularly sought after for insurance coverage disputes.

Intellectual Property

Leading Lawyer

Toronto litigation powerhouse Lenczner Slaght leverages its contentious firepower to focus on IP litigation. A popular choice to handle challenging cases, particularly — but not exclusively — patent disputes, the team routinely represents sophisticated global clients such as Gilead Sciences and L’Oréal Canada. Impressive litigator Sana Halwani anchors the practice and shines in patent disputes; she also handles copyright, trademark and trade secret matters. The group includes Jordana Sanft, who specializes in life sciences cases, and counsel Martin Brandsma, who joined in March 2023 from Bereskin & Parr LLP.

Insolvency and Restructuring

Recommended Lawyers

The team at Lenczner Slaght acts for creditors, debtors, monitors and receivers in insolvency and restructuring litigation. The group’s expertise also spans creditors’ rights, enforcement in secured transactions and receiverships. The practice is jointly led by a Toronto-based duo. Monique Jilesen routinely acts for creditors and receivers in multi-party restructuring and insolvency proceedings; Matthew Lerner leads alongside her and often acts for court-appointed officers and secured creditors.
