Do we even have these in Canada? I don't think I've ever seen one. I've seen them in upstate New York.
Pennies are no longer being made or handed out in change here in Canada, but you can still use them. I could still technically give a cashier pennies, but they wouldn't hand them out in change to anyone else. (I can also pay with half dollar coins, or any other coin that is not in regular circulation) And the prices of items still come to odd numbers that would require pennies, however Canada has implemented a system that if you are using cash it will either round down or round up to the closest 5 cents. If you're using interac or debit, there is no rounding done.
So Kimblebee does have a good question... I just don't know if we have these machines. I've never seen one. I usually roll my coins and bring them to the bank to exchange for bills.
