Only moderators and admins can start new threads in the Countries section. You can just post whatever you need in the regional forum you want. It's broken up into provinces so you can post in whatever province thread is relevant. If it's more of a general thing for Canadians, you could post it in the veggie patch, or other appropriate forum, with something about Canada or for Canadians in the title.
