Termination with cause allows an employer to dismiss an employee immediately, without notice or severance in many circumstances, but Ontario law sets a high threshold before that can happen. Dismissal with cause is one of the hardest decisions a business owner must face. Ending someone's employment immediately carries a personal weight that no amount of legal preparation fully removes, even when the underlying conduct is serious and the decision is clearly justified.

Not every change to your employment is a problem, but sometimes a job change goes too far and crosses a legal line into constructive dismissal. In Ontario, this happens when an employer makes a significant change to your job without your agreement, such as cutting your pay, shifting your hours, or altering your role.
