Canada does have a "bill of rights". It's called the charter of rights and freedoms.
What Canada doesn't have is court that MUST hear this persons case and the violation of his rights by this Saskatchewan human rights commision.
This person's only recourse now is to go to the UN human rights commission or whatever it's called and have Canada condemned, perhaps sent a strongly worded letter.
Boy, it’s tough being an enthusiastic Canadian with $hit like this happening. Bad news. It’s a slow slide into totalitarianism. “Four legs bad, two legs better!”
