President Donald Trump said a 25% tariff on Canada and Mexico could come on February 1 and that a universal tariff isn't off the table.

While much about the threatened tariffs is still unclear, experts predict they would be bad news for all three economies, with few winners.

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.
