Product Liability and Mass Torts


Product liability and mass tort claims are among the most serious challenges an organization can face.

When the survival of a brand or a business hangs in the balance, the world’s leading companies turn to McCarthy Tétrault. We help our clients navigate their most complex product liability and mass tort challenges from start to finish.

We act for companies in a wide range of matters and industries, including medical products and devices, consumer products and services, transportation and automotive products, toxic chemical and environmental matters, and catastrophic events.

Our deep bench strength and expertise across Canada allow us to handle both local litigation and matters with national and/or international scopes. We frequently act as national coordinating counsel in “bet-the-company” litigation involving class actions in multiple Canadian provinces, as well as inventory litigation involving many individual claims across the country.

We work closely with our clients and their legal counsel in other jurisdictions to define and implement a strategy for success from day one. Our litigators have unparalleled courtroom experience with an impressive track record in class actions. We have conducted trials of more tort claims than any comparable firm in the country. With the leverage of our expertise and courtroom success, we are also experienced in sitting down with all parties and brokering creative solutions to achieve victories for our clients outside the courtroom, including in collaboration with our restructuring partners as required.

We will work with your internal team and external advisers to protect your reputation throughout the litigation process. Our firm’s integrated, industry-focused approach allows us to anticipate issues and help prevent and contain product liability and mass tort lawsuits before they begin.
