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.

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.

The president said he planned to put tariffs on America’s neighbors on Feb. 1, as he signed an executive order mandating a sweeping review of U.S. trade policy.
