The Canadian American Business Council says it is deeply concerned by the escalation of the tariff war.

The non-partisan council says tariffs disrupt long-standing business relations on both sides of the border and increase costs and uncertainty.

The council says it’s encouraging both governments to return to constructive negotiations and reach a deal on trade.

Prime Minister Mark Carney is warning Canadians the country’s pivot away from the United States will come at a cost — but insists the alternative would be far worse.

In a national video address released hours after Canada’s retaliatory tariffs kicked in, Carney discussed Canada’s plan to respond to the U.S. trade war by striking new trade deals with other countries.

The video is the latest in a series Carney launched last spring to update Canadians on the government’s polices and its response to U.S. trade actions.

Carney said the goal of those policies is to make Canada stronger and more resilient so that “no country can ever hold us hostage, and that we can live how we want to live.”
