Being let go out of nowhere feels like it must be illegal, but in Ontario it usually is not, on one condition: you have to be paid what you are owed. The warning question depends entirely on whether the employer is claiming cause.
✅Quick answer. You can be fired without warning in Ontario, as long as it is a without-cause dismissal and you receive proper notice or severance. There is no rule requiring warnings first. The picture changes if the employer claims cause over performance, because proving just cause for poor performance normally requires clear warnings and a real opportunity to improve.
Being fired without warning, without cause
For an ordinary without-cause dismissal, an employer does not have to warn you, put you on a plan, or give you a chance to improve. It can simply end your employment, as long as it pays you the notice or severance you are entitled to. So no warning is not the same as no rights: you are still owed your full severance.
When warnings actually matter
Warnings become important when the employer claims cause, especially for performance. To establish just cause for poor performance, an employer generally has to show it told you the standard was not being met, warned you clearly, and gave you a genuine chance to improve, and that you still failed. A sudden for-cause firing for weak performance, with none of that, usually does not hold up.
Ontario courts throw out these claims regularly when the process was missing. In Asgari v. 975866 Ontario Ltd. (2015 ONSC 7508), an employer alleged tardiness and poor performance but had given no documented warnings before firing; the cause claim failed and the employee was awarded pay in lieu of notice. In Waddilove v. 1748960 Ontario Limited (2018 ONSC 448), the employer listed a string of performance complaints but had ignored its own progressive discipline policy and never gave adequate notice of the issues; the court rejected cause and awarded 6.5 months. The lesson is that the paper trail, or the lack of one, usually decides these cases.
If the cause claim fails, you are owed severance
This is the key point for employees. If your employer fired you for cause without the warnings and process the law expects, the cause claim often collapses. And when it does, your dismissal is treated as without cause, meaning you are owed your full severance after all. Do not accept a for-cause label at face value. Even a formal performance improvement plan does not create cause on its own: in Kerner v. Information Builders (Canada) Inc. (2020 ONSC 2975), an 18-year employee was put on a plan for missing sales quotas, yet the employer did not even try to argue just cause at trial, and the court awarded 8 months of notice. A PIP is a management tool, not proof that you can be fired for nothing.
