Prime Minister Justin Trudeau may be taking a 鈥渃ooler heads鈥 approach to the barrage of insults from U.S. President Donald Trump and his top aides as Canada-U.S. trade tensions thicken, but consumers north of the border are proving less stoic.

The extent to which Canadians are willing to do without American products has yet to be seen. But if the online fervor for punishing Trump at the checkout line persists, it may serve as a reminder of Canada鈥檚 economic heft.
