What protects you from these fucking bullies

Refusing service because of a disability is bad. Yes, most of the bylaws and health orders do not require proof of a disability at the point of service because it's none of the bus driver's business what a person's medical condition is. Too many Karen's and Gerry's out there think that it is their business and the mask rules give them free reign to be assholes. This guy can take them to a Human Rights Commission, sure. The problem will come when he has to prove his disability there.

All that said, reading that guy's FB feed tells me he is a conspiratard and he has no actual disability. Good luck to him with that...

My son has an actual disability that can make wearing a mask very difficult, not because it prevents him from breathing but because it agitates him and aggravates his anxiety. His school understands that and makes provisions for him. He has no need nor responsibility to inform anyone of his medical issues, though, and that's the point this cop and the bus driver have failed to realize. Know the law before you try to enforce it, especially if you risk your company coming up on the wrong side of it.
