Class Action Lawyer Toronto

Holding corporations and governments accountable for their wrongdoing.

When corporations or governments harm many people in similar ways, individual lawsuits often aren’t practical. Class action lawsuits allow groups of people to join together and hold these powerful entities accountable. At Campisi LLP, we help people who have been wronged by corporate negligence or government failures seek the justice they deserve.

Contact us today for your free, no-obligation consultation. Let’s discuss your potential claim and how we can help you seek justice.

Trusted Class Action Lawyers in Ontario

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, providing the legal representation needed to take on powerful entities that would otherwise be beyond the reach of individual plaintiffs.

Our team understands 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.

What You Need to Know About Class Actions

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
  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.

Mass Torts: An Alternative Approach

Like a Class Action lawsuit, a Mass Tort allows multiple plaintiffs to advance claims for compensation against defendants for injuries and losses arising out of the same or similar circumstances. However, unlike Class Actions, there is no Representative Plaintiff standing for the interests of the group. This means a judge does not need to determine whether the common issues are significant enough to make a Mass Tort the preferred form of proceeding.

Although legal resources are shared as the lawsuits proceed through the courts, each plaintiff remains in control of their own claim, and each is required to prove the nature and extent of their own damages.

When Mass Torts Make Sense

In more complex cases of corporate, professional, or government negligence, where the type and severity of the harm suffered by victims can vary significantly, a Mass Tort is a flexible and powerful means of providing access to justice for individual plaintiffs.

Class Action Example: Overcharged Bread Products
A class action lawsuit might make sense against a major retail grocer alleged to have unfairly charged consumers for bread products over an established period.

  • The class of potential plaintiffs is huge
  • It’s relatively easy to assign a value to each claim
  • However, the modest value of each claim would not support an individual lawsuit

Mass Tort Example: Unnecessary Surgical Procedures
A mass tort might be suitable against a gynecologist alleged to have performed repeated unnecessary surgical procedures.

  • Liability allegations are similar in every case
  • The impact on each victim varies widely
  • A class action cannot provide appropriate individual compensation
  • Each case requires separate assessment and damages calculation

Advantages of Mass Tort

  1. Access to Justice  Suing large corporations, medical professionals, hospitals, or government agencies is complex and expensive. These well-funded defendants won’t back down unless facing clear defeat or a trial. Many plaintiffs with legitimate claims abandon their cases rather than face years of uphill battle. Joining a mass tort gives survivors the collective strength and determination to pursue justice together.
  2. Efficiency/Cost-Effectiveness  Mass torts allow multiple plaintiffs to share evidence and streamline proceedings:
    • One medical expert opinion can demonstrate negligence across all cases
    • Procedural steps like motions, examinations for discovery, mediation, and pre-trial conferences are held collectively
    • If necessary, claims can be heard before a single judge and jury

    This approach significantly reduces costs and speeds up the legal process.

  3. Strength in Numbers This is perhaps the greatest benefit of participating in a mass tort. While one incident might be dismissed as an honest error, twenty similar incidents become impossible to justify. A pattern of victims suffering the same harm draws attention to and reinforces each individual claim.

    Insurance companies respond to collective risk. The greater their potential exposure, the more seriously they take settlement negotiations. This pressure helps your lawyers advance cases more effectively and creates advantageous settlement opportunities.
