Visually, how Canadian was Orphan Black?

Orphan Black was filmed entirely in or near Toronto, but Graham and John chose to make it generically North American. So, asking as a Brit, was what we saw generally Canadian, or was stuff done specially to make it look more like the USA? As examples: the yellow school buses; the police cars and uniforms; the Promethians with cowboy hats; a farmer with a Confederate flag in his barn, etc. Does Canada have yellow buses, cowboy hats, etc?
