CALGARY — As the threat of 25 per cent tariffs looms over Canada, Alberta’s premier says Ottawa should appoint a “border czar” to work collaboratively with the United States.

Alberta Premier Danielle Smith said Wednesday that Canada should name a “border czar” to work closely with the U.S. on border security, amid the looming threat of a sweeping 25 per cent tariff. Smith suggested a retired military general would be the right person for the post.
