Canola meal is what is left after the Canola oil is extracted. Usually this extraction involves a solvent(hexane) then a desolventizing of the meal. The meal is typically used as a protein supplement for cattle but is alsoused to feed shrimp. Some Canola meal is produced using a double press method and does not use solvents. Can't comment on what effect it has on the beef.
If you are looking for grass fed beef there is a shop in Cochrane called the Cochrane butchery. They have all organic meat - and they also have grass fed. They will also sell you offal.
Also there are a number of elk farms in the outlying areas that will sell you elk - also High Country Bison will sell an entire bison if you can get enough people together to share.
