I haven't seen it at chains or Whole Foods; have you tried calling Oliver's or Tony's or Marczyk Fine Foods? My experience w/ Oliver's is that if it's meat, and they don't have it, they will order it for you. So I'd call them first. All have good phone personnel, so definitely let your fingers do the walking.
Oliver's is 303-733-4629
I'm actually in Toronto. But I bet somebody from Denver on the Canada-US Olympic Hockey final, that if Canada won he would have to send me a picture of himself in Canada olympic gear eating Canadian bacon (or back bacon as it is known here), do-nuts, and drinking Molsons.
Apparently, Molsons and donuts are not too difficult to find in Denver but he was having difficulty finding back bacon
