Trump's long-threatened 25% tariffs against Canada and Mexico began at midnight in Washington DC, as did a new 10% levy against China.
The US is planning worldwide tariffs of 25% for aluminium and steel imports on 12 March. Trump said last month these tariffs were "a big deal" and the "beginning of making America rich again"
Ontario Premier, Doug Ford, has threatened electricity restrictions if the US moves ahead with its tariffs and David Eby, Premier of British Columbia calls for the "worlds to stand together."
"As the President [of the USA] threatens the entire world, it will require the entire world to stand together and draw a line in the sand." - David Eby
Mr Eby recognised that the tariffs are "incredibly challenging" for Canadian companies and for the government but he also said they are "confusing" because they will hurt Americans too.
He gave the example of key exports, like aluminium, which are widely used in construction and will become more expensive in the US. "If you are rebuilding in North Carolina from floods or in [Los Angeles] from fires you are just adding 25% to the cost of your homebuilding," Mr Eby noted.
Trump insists tariffs are needed to "protect" Americans and the US economy, aligning with his commitment towards protectionism.
Doug Ford has threatened electricity restrictions if the US moves ahead with its tariffs. Canada exports enough electricity to power some six million American homes.
While the US also exports electricity to Canada, it imports far more: In 2023 for example, Canada sold $3.2bn worth of power to the US while importing $1.2bn - holding up a $2bn surplus.
