Emigrating to Canada?

I am Canadian, so I can't help you with most of your question. Having said that, please reconsider moving to Calgary. It is a fabulous city and yes, there is a lot of work there, but, you will have a difficult time finding ANY kind of housing. Unless you already know someone living in or near Calgary that can help you (or let you stay with them until something opens up) even apartments (flats) are difficult to come by and there is no cap on the price of rentals. I would hate to see you put in all this effort to come to this country, only to be disappointed that you cannot even find a place to live because the housing market is so tight. Hope you research, research, research first!
