Obtaining a Canadian atpl with your husbands eu-atpl and experience is quite easy just a few (not to difficult written exams) and an ifr flight check as well as a general flight check. Obtaining a Canadian atpl is the easy part, and not too expensive. Finding a well paid (secure) flying position in Canada is almost utopia . Living in Canada and working abroad might financially be more attractive.
Quite a few European pilots are married to Canadian wife's.
