All of our clients, immigrants and refugees, come as permanent residents of Canada. The only difference between a permanent resident of Canada and a Canadian citizen is the right to vote.
My clients who are immigrants or refugees have every right, good or bad, extended to permanent residents. Temporary workers are different. It's not as though they've done something wrong. But an employer could take advantage of them. He could remind them that they're only here on a temporary basis and could be sent back.
I have to agree with your comment. I haven't heard of any temporary workers not being treated the same as other workers. I know of no examples, really, in Saskatchewan.
All I can say is that maybe more efforts could be made to bring people in on a permanent basis, rather than bringing them in temporarily.
