Can they throw me out of Canada for no reason?

Question

I am a US citizen with a valid study permit have lived in Canada most of my life I have a PR application on the way can they throw me out for no reason like if I am just going about my business studying can they just like throw me out?!

Answer 1

I hope they don't throw you back to the states! I don't think they can throw you out for no reason!

Answer 2

Not while you are still in process for PR.

But if as a PR you break a major law, then yes they can.  

Answer 3

They won't while an application is pending. If they want to be jerks, they can haul you in before immigration, but just tell them the truth, you'll be fine.
