I'm not 100% sure, but I believe Canadian bacon is just fried ham.
What do you think bacon is? Ham ;p Basically a piece of pork that was soaked in a brine and/or smoked.
QUOTEIn the United States, ordinary bacon is made only from the pork belly, yielding what is known in Britain as "streaky bacon", or "streaky rashers". In Britain, bacon made from the meat on the back of the pig is referred to as back bacon or back rashers. It usually includes a streaky bit and a lean ovoid bit, and is part of traditional full breakfast commonly eaten in Britain and Ireland. In the United States, back bacon is called Canadian-style bacon or Canadian bacon, but this term refers usually to the lean ovoid portion. What the U.S. terms "Canadian bacon" is actually back bacon rolled in cornmeal. In Canada, it is called peameal bacon, whereas bacon is used generally to refer to strip bacon, which is more common to the Canadian diet. Bacon is also a popular breakfast food.
