If my spouse is studying in Ontario and I have an Open Work Permit, then am I eligible to work in "any" profession? Asking as I heard that one cannot change their profession while on Open Work Permit - so I am a bit confused here. So if I have been working as a Recruitment Officer for the last 10 years outside Canada, and then after obtaining an Open Work Permit in Canada will I be allowed to work as a Supervisor in a Courier company for example?
