If you do that, then chances are that you will only be able to find a very low paying job in Canada. Any role that pays good money won't want to hire someone who is leaving all of the time. With a low salary, once you are finished paying for your accommodations, food, transporation, taxes, etc. while you are working in Canada - you most likely won't have that much money left.
I don't think your plan is very realistic. Have you spent much time in Canada yet?
