Add Comment Question: Are you aloud to be fired for substance abuse Answer: Thank you for your question. My name is Jon Pinkus and I am an employment lawyer at Samfiru Tumarkin LLP. An employer can terminate your employment for any reason, but unless they have just cause for dismissal, they will have to pay you severance. Whether they have just cause on the basis of substance abuse will depend on a variety of factors, including the policy in place at the time of your dismissal, the kind of position that you held, and when and where the substance abuse occurred. I would recommend that you contact me at jon.pinkus@stlawyers.ca so that we can discuss these issues in greater detail.
