An employer is not entitled to:

Medical requests must be reasonable, necessary, and compliant with Ontario privacy laws, including PHIPA.
Can My Employer Ask Why I Am Sick?

As Christopher Achkar, employment lawyer and founder of Achkar Law, explains:
“Understanding what medical information your employer is legally entitled to can be confusing, but disclosing too much or too little can put your rights at risk. Before sharing any details, speak to a lawyer to ensure your privacy and workplace protections are respected.”
