Failure to comply with a court order like this would be civil contempt in Canada. Civil contempt can come with the punishment of jail time and/or fines. Punishment in civil contempt is meant as a remedial action to get the person who is failing to comply to follow the court order and in this case compensate the victims financially.IIRC, if there's a refusal or inability to pay the fines, it can be ruled as criminal contempt, which carries a potential of jail time or community service. I remember when Jordan Peterson was warning that the unaccountable tribunals were going to get abused by gold-diggers, and he was told he was wrong.
I'm not a lawyer but I do know that you can deny service as long as it isn't a discriminatory act against a protected group. If the people you don't like can't be shown to be chosen because they are in a legally protected group it would be fair game. If however it is found the people you don't like all follow a certain pattern and are part of a protected group(s) then there well could be a possible human rights violation.Are there any lawyers in this group from Canada? Does anyone know if you have a right to deny service to someone if you just don't like them? Yaniv is a proven racist, an alleged pedophile and, clearly, a predator. Do people that own businesses (any business) have a right to just say no, I won't serve you?
If all the people you dislike are black, and you deny them service you better be able to prove that you aren't making that choice of disliking them because of the color of their skin.
