Politicians and industry leaders have long pushed to remove barriers to interprovincial trade. Trump’s tariffs are giving the effort new momentum.

US President Donald Trump said trade talks with Canada are not a focus for his administration right now, and instead of negotiating a deal he may decide to just leave existing import taxes in place.

Trump said the U.S. has not 'had a lot of luck' with Canada during negotiations on a new trade and security deal, suggesting the two countries may end up with no new agreement.
