I took the Canadian ATPL exams just to get them done.As I recall there was no credit even if I opted just to start with a commercial.Saying that though there a peice of cake compared to the UK exams.2 exams and your instrument.spent a solid 14 days to prep for them and 85+ on every one.
I sponsored myself as a Landed Immigrant.Pilot scores near the top of the tree(its based on a points system)Only you have to have been working as a pilot for more than 12 months to claim it as your job/vocation in life.
Its great over here!!!
