Fairly easy perhaps as common sense lets you know a pound of beef should not cost the same as a pound of peppers? 

Canada is the same or worse: 
"Of the roughly $200 billion spent to subsidize U.S. commodity crops from 1995 to 2010, roughly two-thirds went to animal-feed crops.   Farmers who grow fruits, vegetables and tree nuts, on the other hand, receive no regular direct subsidies, though there are some small programs that aid apple farmers and other growers."  Washington Post

I would say that is a massive subsidy wouldn't you (about $150 billion)?  Our government is too afraid to even tell you low effort types that the number one cause of climate change is not the oil business, but livestock and the consumption of meat.   Though they are neck and neck. That also does not take into account the subsidies they receive for millions of acres of farm land to grow food for livestock.   Many studies out there I just chose the quickest reputable google find.
