Justin Trudeau, Canada’s prime minister, announces tit-for-tat 25% tariffs and warns of impeded access to ‘vital goods critical to US security’

The leaders of Canada and Mexico have hit back after Donald Trump signed an order authorizing dramatic tariffs on their goods, along with imports from China.

Canada’s prime minister, Justin Trudeau, on Saturday night made a televised address announcing concrete measures including a tit-for-tat 25% tariff phased in across $155bn worth of American products. Trudeau said Trump had put US consumers’ and industries’ access to much-needed Canadian critical minerals and resources including oil, energy and timber under threat, and promised to work with Canada’s provinces to review dealings with the United States.
