B-C is launching a Canadian trade challenge against Alberta for banning B-C wines in retaliation for the British Columbia government’s plan to limit bitumen shipments until spill cleanup concerns are met. B-C’s trade minister says Alberta’s actions threaten the wine industry and are inconsistent with interprovincial trade obligations. Alberta’s trade minister argues the boycott is a reasonable response to B-C’s actions, which he says threaten the economic security of hundreds of thousands of Canadians.
