There are no gift taxes in Canada [there are also no death taxes in Canada, without them gift taxes are not so much needed.]I'm pretty sure you can't just give someone millions of dollars without raising a few eyebrows... and then getting taxed. big time.
As long as everything is above board [via check or bank transfer as opposed to via bricks of coke or cash] there is no problem. Sure if you go into a bank branch to do it the person you are dealing with will raise an eyebrow but fuck him/her. It isn't illegal.
