BC Thoughts,

A stronger case can be made that both Canada and the US, like most advanced nations with major agricultural components, have over the years constructed systems and implemented policies to protect those components.  The US subsidizes many agricultural producer groups directly through cash subsidies, through tariffs and imbargoes and indirectly through programs ostensibly intended to achieve other goals (examples of the latter being foreign aid tied to US  agricultural purchases and export and the support of corn production under the guise of substitution of ethanol for fossil fuels).

While both Canada and the US should be seeking compromises to judiciously discard excessive protective policies and programs that have grown up over the last 8 decades, it does not follow that Canada should unilaterally make cuts.
