There are several mouse breeders in Canada. I use
Coast to Coast Mice. I can't comment on shipping prices since they are less than 20 minutes from my house and I pick up, though I do know they ship exactly where they name says they ship!
I can comment on their facility and quality. Both very clean and in excellent condition. The mice are packed very well even for the short trip home my order has!
Drop them an email, I am sure they can help you out.
