Compared to the process in getting a Canadian Aviation Medical, the FAA medical is more straight forward.
All FAA Aviation Medical Examiners have the required forms on hand-- they have serial numbers on them and the actual aviation medical certificate. You fill out a portion, they fill out the rest, and you then leave the doctor's office with the aviation medical certificate in hand. Unlike the Canadian document, it is a "one-time" certificate, no boxes on the back side for revalidation stamps-- when you go for another medical, you do the same form, and you walk out again with a fresh paper.
And of course, no bill in the mail from the FAA months later shaking you down for money!
While there are FAA Aviation Medical Examiners in Canada (there is at least one in almost every country of the world), if you are going to travel to the United States anyways, you may want to check what the examiner's fees are in the USA. Normally, quite a bit cheaper-- I've found them charging as much as a 1/4 or a 1/5 of what the Canadian resident FAA AME wants-- if you live near the border, the savings themselves pay for gas, meals, some shopping.
