Can my employer fire me because i was on sick leave?

Verified 31 July 2026 Law of Quebec and Canada General information, not legal advice

Short answer

In Quebec, an employer is prohibited from dismissing, suspending, transferring or penalizing an employee because they exercised a right provided for by the Act respecting labour standards, which includes absences for illness or family obligations. The remedy is a complaint for a prohibited practice with the CNESST (Quebec's labour standards, health and safety board), within 45 days of the measure (ss. 122 and 123).

In detail

The Act lists several prohibited grounds: exercising a right provided for by the Act, a pregnancy, having given information to the CNESST or testified in a proceeding, a seizure of wages, being a caregiver, and reaching the age of retirement, among others.

The presumption is the heart of this remedy. If the employee shows that they exercised a right and that a penalty followed, they are presumed to have been penalized on that ground. The employer must then establish another good and sufficient cause, one that is serious and genuine, and not a pretext.

If the complaint is allowed, the Tribunal administratif du travail (TAT, Quebec's labour tribunal) may order reinstatement, cancellation of the penalty, and payment of the equivalent of the wages and benefits that were lost. Nothing requires a minimum length of service.

What to document

The exact dates of your absences and of the notices you gave the employer, the medical certificates, the date of the penalty, the reasons given, and any change in tone, schedule or treatment that occurred after the absence. It is the dates placed end to end that reveal a connection.

What this page is not

This is general legal information about the law of Quebec and Canada, dated and sourced. It is not legal advice, not a strategy, and not a prediction about the outcome of a case. In Quebec, only lawyers and notaries may give legal advice (Act respecting the Barreau du Québec, ss. 128 and 133). Laws and amounts change: the official source always prevails over us.
