Class Action Questions

General information about how class actions work in Canada. For questions about a specific claim, open that matter above or call our team.

What qualifies as a class action lawsuit?

A class action is a single proceeding brought on behalf of a group of people who have the same legal complaint against the same defendant. Rather than each person bringing a separate claim, one representative plaintiff advances the claim for the whole group.

Before a class action can proceed, a court must certify it. Certification asks whether the group is identifiable, whether the claims raise common issues, and whether a class proceeding is a workable way to resolve them. Product liability, privacy breaches and institutional harm are common subjects of class actions in Canada.

How do I know if I am a class member?

When a court certifies a class action, it approves a class definition. That definition sets out who the claim covers, usually by reference to what happened, where, and over what period. If you fall within the definition, you are a class member.

Each matter listed on this page sets out who the claim covers. If you are not certain whether the definition applies to you, speak with a lawyer rather than assuming either way.

If I am a class member, how do I take part?

In most Canadian class actions you do not need to do anything to be included. If you fall within the class definition, you are part of the class automatically, and you would only need to act if you wanted to remove yourself from it.

Where a settlement is reached, class members are usually asked to submit a claim in order to receive their share.

How long does a class action take?

Class actions move more slowly than individual claims because of the steps involved. A claim is filed, the court decides whether to certify it, the parties exchange evidence, and the matter then resolves either by settlement or at trial.

Where a settlement is reached, it must be approved by the court at a hearing before any money is distributed. Timelines vary widely between matters.
