About Conspiracy
When workplace relationships break down, an individual may feel that multiple people worked together to intentionally harm them. In everyday language, this might be called a 'conspiracy.' However, in Ontario civil law, 'conspiracy' is a specific and difficult-to-prove tort. Pleading civil conspiracy in an employment dispute requires proving that two or more entities formed an agreement to commit an unlawful act, or to commit a lawful act using unlawful means, with the intention of causing financial harm.
In Ontario employment law, conspiracy claims arise in two main ways. First, an employee might try to sue their former employer, alleging that management and human resources conspired to manufacture a false reason to fire them. Second, an employer might sue former workers, alleging they conspired with a competitor to steal trade secrets or orchestrate a mass resignation.
For employees, bringing a conspiracy claim against a former employer is notoriously difficult. Under Ontario law, it is generally recognized that a corporation cannot conspire with itself or its own employees when those employees are acting within the scope of their typical duties. Furthermore, terminating an employee is not inherently an unlawful act; if an employer fails to provide appropriate notice or severance, it is simply a breach of the employment contract (wrongful dismissal). Because of these legal barriers, Ontario courts frequently strike out (dismiss) employee conspiracy claims early in the litigation process for lacking the necessary "material facts."
Unionized employees face an additional barrier. If a worker alleges that their union and employer conspired against them to deny their rights or drop a grievance, Ontario courts will almost universally refuse to hear the case. Due to the framework established under the Labour Relations Act and key Supreme Court precedents, disputes rooted in collective agreements must be resolved through grievance arbitration, not civil lawsuits.
Because pleading a complex tort requires a high burden of proof and strict legal formatting, these situations demand specialized assessment. The facts of every workplace dispute are unique, and you should seek professional legal advice to understand whether you have a viable conspiracy claim or if another legal remedy, such as claiming damages for bad faith in the manner of dismissal, is more appropriate.
Frequently Asked Questions
Can I sue my boss and HR for conspiring to fire me?
Generally, no. A corporation cannot conspire with its own employees when they are carrying out their official management duties, a concept known as the corporate identity doctrine. If you were unfairly fired without notice, your legal remedy is typically a wrongful dismissal claim against the company, not a conspiracy claim against individual managers.
What do I need to prove to win a civil conspiracy claim in Ontario?
You must prove that two or more distinct parties reached an agreement to act unlawfully (or use unlawful means), that they directed their conduct at you knowing it would cause injury, and that you actually suffered financial damages as a result. You must have concrete evidence of this agreement, not just a suspicion.
I am in a union. Can I sue my union and employer for colluding against me?
Civil courts in Ontario generally do not have the jurisdiction to hear these claims. Under the Labour Relations Act and established legal frameworks, disputes between a unionized worker, their union, and their employer must be resolved through the grievance and arbitration process or by the Ontario Labour Relations Board.
Can my employer sue me for conspiracy if I quit to join a competitor?
Yes. If an employer has evidence that you colluded with colleagues or a competitor to unlawfully steal confidential information, solicit clients, or breach your fiduciary duties before resigning, they may file a civil conspiracy claim against you.
Why do judges often throw out conspiracy claims in employment lawsuits?
Ontario's Rules of Civil Procedure require plaintiffs to plead specific 'material facts' (the who, what, when, where, and how) when alleging complex torts. Simply claiming that the employer acted maliciously or coordinated your termination is not enough to maintain a conspiracy claim, leading courts to strike them out.
When should I consult an employment lawyer about a conspiracy?
You should speak to a lawyer before relying on conspiracy in a legal claim. Alleging a serious tort without sufficient evidence can result in your claim being struck and you being ordered to pay the other side's legal costs. A professional can help identify more reliable claims, like wrongful dismissal.
Is there a time limit to file a conspiracy claim in Ontario?
Yes. Under Ontario's Limitations Act, 2002, you generally have exactly two years from the date you discovered, or reasonably ought to have discovered, the conspiracy to file a civil claim.
Common Scenarios
- An employee suspects their direct supervisor and human resources manufactured false performance warnings over several months to create a paper trail for a "just cause" termination, prompting the employee to incorrectly attempt a conspiracy lawsuit instead of a wrongful dismissal claim.
- A unionized worker believes their union representative and the company's HR director made a back-room deal to drop their grievance for unjust discipline, but finds the civil court refuses to hear the case due to the Labour Relations Act.
- A senior executive coordinates with two colleagues and a competitor to resign on the same day, immediately launching a rival company utilizing the former employer's confidential client lists, leading the employer to sue all involved for civil conspiracy.
- Delivery drivers launch a class action lawsuit alleging that a parent franchisor and multiple individual franchise owners unlawfully coordinated to misclassify them as independent contractors to avoid paying minimum wage and termination pay.
What You Should Know
- Focus on the strongest claim. For most terminated employees in Ontario, pursuing proper notice or severance pay through a wrongful dismissal claim is much faster and more successful than trying to prove a complex conspiracy.
- Gather concrete documentation. If alleging conspiracy, mere suspicion that people were 'out to get you' is not legally sufficient; you need emails, texts, or witness testimony demonstrating a clear agreement to commit an unlawful act.
- Do not add conspiracy claims just to make an employer look bad. Including baseless allegations of conspiracy in a statement of claim can lead to those sections being struck by a judge, potentially resulting in early cost awards against you.
- Consult an employment lawyer to properly frame your lawsuit. A lawyer can determine if an employer's harsh conduct actually meets the legal test for civil conspiracy, or if it instead warrants aggravated or punitive damages for bad faith.

This is an appeal to the Court of Appeal from a motion judge's decision striking the appellant's statements of claim and denying leave to amend them. The appellant, a union member, originally sued the respondents, who were fellow union members, and later sought to amend his pleadings to add the union as a party and allege civil conspiracy. The motion judge dismissed the motion to amend, finding that the new claims for civil conspiracy and declaratory relief against the union were statute-barred. The Court of Appeal dismissed the appeal because the initial pleadings did not support a claim for civil conspiracy and the events were known to the appellant out of time. The motion judge's order striking the claims stands, and the respondents were awarded $10,000 in costs.
