Well, one reason is that Canada had a ~15 year bread price-fixing scandal come to light somewhat recently.
And the same people that colluded on bread just so happen to sell other grocery goods. Some people think: "hey, maybe we should check out the other stuff they sell". Which seems reasonable to me.
From an anecdotal standpoint, when many of the groceries I buy seem to have gone up in price at a rate well outpacing inflation, I can't help but wonder what the hell is going on.
