Find local abbatoirs (the politically correct term for a slaughterhouse) in your area.
My goodness - you're in "beef country" in Alberta - they should be on every street corner !
(just jealous

)
I found one only 25 minutes from where I live in Ottawa that has beef, pork and sheep!
You can ask for "scrap" - that's exactly what we Raw feeders use - bones, organs, scrap meat.
I found the ones in my region by going on Google. Search "Alberta government licensed abbatoirs" and there shouls be about a million in your area - good luck !
oh - and you'll find out just how much CHEAPER it will be to get meat for your self as well ! I'm ordering 1/4 side of beef at $1.99 packaged the way I want , and all ! Steak at $1.99 lb !!!!!
