US President Donald Trump said that he was thinking of imposing the tariffs on Canada and Mexico by February 1.

The focus on American prosperity and national security is the latest pivot by Canadian officials as the country tries to find its footing with the new Trump administration, and - more urgently - avert the threat of blanket 25% import tariffs imposed by the US, its largest trade partner and closest ally.

As Donald Trump teases steeper tariffs on Canadian products, Canada readies its $37 billion in retaliatory measures and politicians begin debating the move. Targets will likely be critical minerals with national unity and economic ties to the center.
