Canada is closer to the JAA licence I believe but still not as tough, better you ask someone from canada... far fewer opportunities up there and most of them cold. If you do the JAA licence and then add on the FAA the FAA will cost next to nothing as you'll already have the hours... sitting the FAA exam is maybe a couple of hundred dollars and you won't fail it... sitting the JAA exams costs well over $2000 and you may have to sit them more than once if you fail to get a partial pass, which happens often enough.. even re-sitting a couple of partials will set you back maybe $400 plus travelling... If money is a major concern and you can work in the US I suggest you go that route and once estblished in the industry with a couple of thousand hours behind you, then think about whether you want to come back to Europe...
Anyway... whatever you choose... very best of luck
