Employers can be private companies.
Medical tests
In the past, employers often screened out applicants with disabilities based on medical information on application forms, or from pre-employment medical exams. The Commission takes the position that requiring such information as part of the application screening process violates subsection 23(2) of the Code.
So if private companies can't screen employees without violating the law......how can a hokey venue?
Labour laws are made by legislation.
Legislation must follow the charter rights.
Please tell me that you've put more thought into your Covid denial than this argument.
