class action lawyer

Although everyone has heard of class action lawsuits, there is a lot of confusion about them in Ontario. Basically, they are big lawsuits where a designated person called the representative plaintiff argues the claim against large entities like corporations and the government on behalf of all the potential members of the same class. The costs to run the lawsuit are carried by the law firm and are paid when the action is settled or won in court. Without class actions, it would be almost impossible for the public to hold big business and governments responsible for their actions. There is a broad range of potential class actions and new causes of action are discovered all the time.  

At Campisi LLP, we represent victims of corporate and government wrongdoing and negligence in the following types of Class Actions:

What you need to know


If the following apply to you and could also apply to others, you might have a Class Action claim:


  1. There is a cause of action – there must be a legal wrong committed, not just a moral wrong;
  2. There is an identifiable class – it must be possible to determine who has been affected by the wrong actions;
  3. There are common issues – the issues experienced must be common and must be a significant component of the claim;
  4. A class action is the preferable means of resolving the issue – for example, if only a few people are involved, there may be more convenient means to get the necessary results; and
  5. There is someone to represent the class as representative plaintiff – there must be someone willing to guide the action whose experience is typical for the class.


If these criteria apply to you, we are pleased to offer a free, no-obligation consultation to explain the class action process in detail, and to advise you concerning your potential claim. We understand how corporations and government institutions work. We know that their decisions, errors and omissions can cause damages that might appear too small to pursue individually. In these cases, the overall damages might be large enough when grouped together to pursue on a class action basis. Therefore, we investigate potential claims thoroughly and as efficiently as the circumstances of the claim allow in order to provide you with an opinion you can trust.
