You can ask your employer to give you a work certificate when your job ends.
A work certificate states:
The work certificate does not state if you were a good worker or not. It just gives details about your work.
A work certificate is not a Record of Employment, which your employer must give you when you stop work. You need the Record of Employment if you are going to apply for employment insurance benefits.
Your employer has dismissed you for good cause without notice. You do not agree and do not think you should have been dismissed. You think this is wrongful dismissal. You can file a complaint with the Commission des normes du travail (Labour Standards Commission).
In order to file a complaint, you must:
You have forty-five (45) days after you are dismissed to mail or deliver your written complaint to the Commission des normes du travail (Labour Standards Commission). If you mail the complaint, it is best to send it by registered mail.
The Commission will first make sure it can look into your complaint. It will inform you in writing once it decides it can handle your complaint.
