the reason food is so expensive is because of fuel costs from the last few years, which were further not-helped by both an increase in federal taxes on fuel and the semi-official policy of weakening the CAD against the USD to support exports that weakens purchasing power. the effort appeals to economically illiterate constituents who support "price controls."
if you want to know where canada is on its de-kulakization spiral, the state is blaming "price gougers" for its policy failures, next are hoarders, speculators and probably "international bankers," on the list of clichés.
