Excuse me, do you personally know such people? Where do you get this info from? I would appreciate if you could answer.canvis2006 said:absolutely wrong. As long as he mentions he was deported, and satisfies other criteria and passes the background checks, he will be ok.
There are hundreds of thousands who were illegal in USA, and obtained Canadian PR. As long as he does not have a criminal record in USA, he will be fine. But he must declare it as CIC has access to US systems to verify.
