'Nothing off the table' in Canada's response to US tariff threat

Canadian political leaders say "nothing is off the table" when it comes to responding to potential 25% tariffs from the US, days before they could come into force.

But strains are showing in "Team Canada" when it comes to whether energy supply should be a tool in a possible tariff war with the US.

Canadian officials argue (tariffs) would undermine the US economy, increase inflation for American consumers - including raising prices at the petrol pump - and hamper investment.

They also warn tariffs could undermine national security, given Canada, a US ally, is a key source of energy and critical minerals.
