it's a very easy process. call canada customs in advance (at least an hour up to 72 hours). after you land get progressives to the customs ramp. the inspection is a joke, just have your paperwork, they will give you a small piece of paper. You don't need to call or contact them before departure. call customs at least an hour before dep. then go for it, that's it. There are user fees for airspace and they will send it to the address where the airplane is registered, come to think of it i have a second notice bill on my nightstand, oops. refer to you aopa airport directory they have a good section on this with proper phone#'s. hope this helps.
