Canadian bacon is a type of bacon that is made from lean pork. It is usually cut into thin round slices and is different from regular bacon which usually comes from pork bellies. Canadian bacon is usually treated with something called a curing solution so it can last longer, and then later on is smoked or cooked until it is crispy and crunchy. It is often used on pizza or in other dishes and is usually lower in fat and calories than regular bacon.
