Suppose a store is considering an employee for hire when a social media review finds views that conflict with both prevailing governmental advice as well as the views of management. If the discovery of this information were to be the reason someone was declined an interview, according to Canadian law, would the declination be considered legal? If it is, would that status change if the person's religious views are what guided them to their opinion?
I am hoping to discover statutes and/or similar case law that relate to this. The closer to Alberta law, the more useful it is for me personally, but Canadian law in general would be more useful for the site at large.
