U.S. Trade Representative Katherine Tai discussed the proposal with International Trade Minister Mary Ng during a call Monday ahead of the USMCA Free Trade Commission meeting, according to the U.S. readout. Ng brought up the administration’s plans to expand Buy America procurement restrictions, according to Global Affairs Canada’s summary. (The Logic)

Talking point: Tai’s comments are the first U.S. response to the Liberal government’s DST plan, which it finally outlined in the federal budget last month. U.S. tech trade groups have lobbied the USTR to intervene against the proposal and others like it, calling them discriminatory trade barriers that would primarily impact large American firms. The agency has conducted investigations of other countries’ DSTs and proposed retaliatory tariffs in some cases. It has yet to launch similar action over Ottawa’s proposal.
