President Donald Trump late Thursday threatened a 35% tariff on goods imported from Canada, a dramatic escalation in an on-again, off-again trade war with America’s northern neighbor and one of its most important trading partners.

The pause on the biggest of Trump's tariffs won't end this week, but the president continues to pledge steep new duties against major countries.

The president said the blanket 35% would be on top of tariffs on certain sectors. That’s higher than the previous 25% rate.
