I always thought there was some political hate towards Toronto, as they seemingly control the provincial election - get their party in (Liberals), who in turn focus solely on the GTA, while the rest of the province gets the shaft.
I suspect there's a lot of communities nearby who resent that they get invaded on the weekend by Torontonians who treat their town like a 8 year old does a birthday party room at the local movie theatre.
I suspect a lot of the population hate french people in general. They push english/french signs on everyone else, yet don't do the bilingual thing themselves. They complain, bitch about damn near everything and get significant political perks simply by being belligerent. They want and have their own set of rules for some unknown godly reason. Bitching about separating. I also think people generally hate listening to them speak. That accent is insufferable and they are typically thought to rude in general.
