I do ship to Canada. Please be aware of the shipping cost, VAT taxes and customs fees however. This can add up. I ship USPS 6-10 day priority but it can take longer as customs can hold it for a longer time.
The punch will work with Canadian coins. Be aware though that many of your current coinage has a steel core with a nickel clad over it. This steel core, if exposed, can damage the reduction dies. The dies are designed for non-ferrous metals. Silver, brass, copper, gold, platinum, etc.
