US tariffs threaten Canada trade

Archived — this story has rotated out of today’s deck. It is kept here in full.

The gist

U.S. threatens 50% tariffs on Canadian goods starting Aug. 19. Canada warns it will stop negotiating and retaliate if tariffs hit.

Background

The U.S. and Canada are in intense trade negotiations as a deadline approaches for new 50% tariffs on a wide range of Canadian products, including motor vehicles, dairy, alcohol, hockey sticks, and cement. The tariffs, announced by President Trump, are a response to what Washington calls Canada's discriminatory trade practices, such as provincial bans on U.S. liquor and dairy quotas. Canada has threatened to retaliate if the tariffs take effect, potentially reviving earlier retaliatory tariffs.
