Actually, "Canadian" bacon (referred to as "back bacon" in Canada) is just cured pork loin. Around here, I can often find pork loin for less than $2 per pound, but "Canadian" bacon is usually quite a bit more expensive. I usually just use some sort of cured ham in my omelets and saute it with the mushrooms and jalapenos before putting it in the omelet with the cheese and folding it over.
