Add Comment Question: Must an employer in Ontario give two written warnings before firing an employee? Answer: It depends on the severity of the offence. Employers have to use progressive discipline, which will include written warnings and suspensions, but in situations of very serious misconduct (theft, for example), no warnings will be required. If you've been terminated for misconduct or poor performance, it is extremely important that you discuss your matter with one of our employment lawyers. You may still be owed a significant severance package.
