I remember a guy on the forum who wanted to do that and he found a way of going back to college. He found a college geared towards older students in BC and he and his wife moved. As a student, your spouse gets an open work permit although they may not choose to work. Doesn't matter. After a study permit, there are other ways of applying to immigrate. Say the spouse got a skilled full time job while you study, after 2 years, you as a couple can apply for permanent residency under Canadian Experience class. No age limit, no requirement to work after that. Or if you complete at least a 2 year course and get a post-grad work permit and get a skilled job yourself, you would be able to apply for your PR under Canadian experience class after a year of working.
