They are pretty much the same. No big diferences at all. But If you look for instance at the euro spec vs us there are some. Like optionnal lighting, Rims and colored dash trim. If I remember correctly even different Steroes aswell
Canadian cars in general have DRL by law. A lot of times CND cars will have a frost plug installed (its like a block heater you plug in overnight), not sure if they do that on US cars. Even my Z came with one.
