US-Canada trade dispute escalates after Carney announces retaliatory tariffs

Summary

Canada and the US were closing in on a trade deal earlier this week until the negotiations fell apart. Both sides blame each other for last-minute changes to the terms. Canada’s Prime Minister Mark Carney has announced retaliatory tariffs on the United States after Washington imposed a 50 percent levy on 20-billion-dollars worth of Canadian goods. On Saturday, he addressed the nation for the first time since the talks collapsed, as Charlotte Lam explains.
