There are billions more pennies lying in jars in people's houses than are in regular circulation. Even if we were to stop minting new pennies today we could coax the population to turn their pennies in and we wouldn't run out for centuries to come. There is no shortage of pennies. I don't care what Canada does, you're not going to take my pennies away.
A good way - a single day where each turned in penny gives you 3 "cents" in exchange. Of course you would be giving out only dollar or higher bills in such a program.
