Add Comment Question: In Ontario can I be fired for being sick if I exceeded my sick days. We are union and get 10 sick days a year. I have all my medical documentation from the hospital. Answer: Hello and thank you for your question. In Ontario, employers must accommodate employees who require leaves of absence for legitimate medical reasons. However, as you are unionized I would recommend you speak to your union steward if you feel you have been fired as a result of taking sick days for your medical condition, or feel you will be fired in the near future.
