The Trump administration is demanding upfront concessions as a precondition of negotiations on the United States-Mexico-Canada Agreement, sources say, as Prime Minister Mark Carney pushed back at the suggestion Washington is dictating the terms.

Two sources familiar with the talks say U.S. President Donald Trump’s administration has asked Canada to unilaterally change or scrap domestic policies, from dairy to provincial bans on American liquor, or the Online Streaming Act and the Online News Act, before it will sit down to negotiate.

The Globe is not identifying the sources as they were not authorized to discuss the matter publicly.
