Getting a degree or diploma or certificate, cheap or not cheap, does not guarantee employment or residency in Canada.
Canadian graduates do volunteer work, part-time work and perhaps a couple of weird jobs before finding an entry-level job closer to their field. Then if they are lucky and make good connections, they can work their way up.
If you really want to see the cost of tuition fees, check college websites: http://en.wikipedia.org/wiki/List_of_colleges_in_Canada
or university websites: http://www.aucc.ca/canadian-universities/our-universities/
You have to research by yourself. Don't expect strangers to tell you what to study. I know it sounds harsh but it's YOUR LIFE.
