Canadian Stacking

Wondering what my fellow Canadians prefer to stack in terms of coins! I’ve got a maple and eagle, with a kangaroo and brittania on the way so I can hopefully determine which mint I want to stack mainly. Thinking it will be either brits or kangaroos since I’m not a huge fan of the maple leaf and don’t want to pay tax for eagles. So far I’m only in as far as fractionals but would love a buffalo one day. Any issues selling kangaroos or brits in Canada?
