Constructive Dismissal in Ontario: Signs and Next Steps

Common signs of constructive dismissal
Examples include a large pay cut, demotion, relocation you did not agree to, removal of key duties, or sustained harassment that management ignores. One minor change is usually not enough. Courts look at the full pattern and whether a reasonable person would feel the employer repudiated the contract.
Quit, stay, or negotiate first
Do not resign quickly without advice. Leaving too early can hurt your claim; staying too long in intolerable conditions can also be risky. Many employees first document changes, raise concerns in writing, and speak with an employment lawyer in Milton before deciding next steps.
What compensation may be available
If constructive dismissal is proven, you may be entitled to notice or severance under common law, which is often more than ESA minimums. Use our severance estimator as a starting point, then review your package with counsel. See also wrongful dismissal in Ontario.

Do I have to quit to claim constructive dismissal?
In many cases you must show you treated the contract as ended, but timing and documentation matter. Get advice before resigning.
