Antman, I've just finnished redoing my licence from SA to Canadian. Exams are fairly straightforward but do require a fair bit of work. Budget around $3000 all in with books exam fees etc to get it done and around two months in total (the longest wait is having your log book verified).
On the work front once you're over 5000 hours your pretty much set anything less than that be prepared to take BIG steps backwards.
On the salary front, not fantastic by eny means but none the less well worth the move.
