"All subsidies should end from all countries."
And everyone should love their neighbour, and violence  should end, and we shouldn't be cruel to puppies, blah, blah, blah.
Sorry, but your comment, and Bernier's fatuous warblings belong in the realm of fantasy.
According to the U.S. WTO notification, in 2012 direct payments to farmers under income support programs amounted to US$3.837 billion.
Price supports for the U.S. dairy industry under the Dairy Products Price Support Program and the national dairy market loss payments program, were $403 million in 2012.
The whole world subsidizes its agriculture industries. And to compete, Canada does the same. 
Bernier's no-regulations philosophy is analogous to a team that says its wants to play in the NFL but doesn't believe in wearing any protective gear. Purists.
They would end up in hospital pretty quickly, just like Canada's economy would in a world of protected economies.
