Canadians woke up to uncertainty as U.S. President Donald Trump moves ahead with his plan to impose 25% tariffs on Canadian goods today.

Prime Minister Justin Trudeau will address the country at 10:30 a.m. EST.

Canada’s retaliatory tariff plan includes two phases, announced by Trudeau last month, said to total $30 billion in U.S. goods in the immediate term. A further round of tariffs on a wider list of American products, valued at $125 billion, is expected to come into effect 21 days later, following a public comment period.

Tariffs will have a massive impact on Newfoundland and Labrador, potentially putting between 10,000 to 20,000 jobs at risk in industries like fishing, mining, and oil and gas, as well as people who work in the service industries.
