Class Actions
Our lawyers have acted successfully in a variety of class action lawsuits—for both plaintiffs and defendants—demonstrating the strategic thinking, rigor, patience, and complex file management required to navigate such matters. We are deeply familiar with the intricacies of the statutory frameworks that govern class proceedings across Canada, and the unique challenges that this category of litigation can pose.
Our recent class action litigation areas include:
- Securities and shareholder fights
- Consumer protection
- Product liability
- Insurance matters
- Negligence claims
- Mass torts and institutional abuse
- Pension fund administration
We enjoy teaming with co-counsel at other prominent law firms in Toronto and across Canada to advance plaintiff-side cases with a strong public interest element, as we are presently doing against Meta/Facebook (on behalf of minor users of Instagram) and the Government of Canada (on behalf of Manitoban farmers).
