As U.S. President Donald Trump renews his tariff threat on Canadian products, Alberta Premier Danielle Smith says diplomacy, not retaliation, is the best way for the country to stifle the risk of punishing new trade sanctions.

Alberta Premier Danielle Smith says Prime Minister Justin Trudeau has complicated ongoing negotiations with the U.S. after newly inaugurated President Donald Trump set a date to impose tariffs against Canada. Smith told reporters at a Tuesday morning news conference the focus should be on diplomacy and ending talks about retaliatory tariffs.

Canada’s top export to the United States is energy products, mostly oil and gas. Almost all of the crude oil that Canada exports goes to the U.S., and most of it comes from Alberta. Alberta exports about 80 per cent of the crude oil it produces.
