Trapping minnows in Ontario

[Shellback]

Are there laws regarding trapping minnows for bait in Ontario? I seem to remember reading that it's illegal for non residents. I may be mistaken and am thinking about from state to state in the US. What I'm considering is setting a minnow trap at the dock of a Canadian resident who allows me to use his dock for my boat while visiting. I guess I could have him set the trap, but would it be legal for me to have the minnows aboard my boat with no sales receipt? I enjoy fishing Canada too much to jeopardize my visits.
