Canadian licences are no more than a small piece of paper about 3" x4.5", the medical is similar, however I got a letter from Transport Canada this week telling me that they are introducing a new licence.
So it can carry the pages for upgrades and medicals it will be in passport form and will be provided free of charge in exchange for current scrap. Unfortunately, in order to comply with international agreements and because it will have a picture in it, it will have to be replaced every five years. I wonder how much they can charge us for that? A passport is currently in the order of $85 to renew.
In order not to lose or mangle them I have been carrying around my licence etc in my original ( 1962) British licence cover. (Yes, it was Pooh coloured then too.) Guess that finally will have to go.
