In Canada, Currency Act of 1985 prohibits consumers from using unreasonable amounts of coins to pay for purchases. This means you can’t pay for an item in all coins (especially if it’s over $10). Even the use of dollar-coins is limited. The shop owner has the right to choose whether or not he wants to take your coins but doesn’t have to.

留住零钱
在加拿大，1985年实施的货币法禁止消费者用大数量的硬币购买商品。这意味着你不能用所有的硬币来支买一个商品（特别是超过10美元的）。即便对美元硬币的使用美元限制。店主有权力决定是否要你的硬币，但是不一定非要收。
