I can’t speak for Canada, but in the US some banks require rolls while others require loose. The bank I worked for we required loose because we put them through a machine coin sorter. Smaller banks the tellers sometimes have to hand roll coins themselves so if you’re bringing in an excessive amount they have bank policies that it must be rolls. On the other hand we would have to break open any rolls you brought in because it’s very easy to fake rolled coins.
