First find a bank that will take rolled coin, many do not. Some banks weigh rolls that you bring in. If so you will only get away with one or two Canadians per roll.
Myself, I started a Canadian coin collection because of all the pennies, nickel and dimes I was finding. Now I go to Canada once every couple a months to dump the Canadian coins I don't want and buy boxes of Canadian coins to search. It costs me $8 to cross using the detroit windsor tunnel round trip.
