Washington for years has unsuccessfully challenged the way that Ottawa has allocated the USMCA dairy quotas. While some said dropping the digital services tax made Canada look weak, it has not been politically explosive and the tax was a little-known measure for many Canadians. A spokesperson for the US ambassador in Ottawa declined to comment on trade talks. "Our supply management system will never be on the table," the statement said. Dairy Farmers of Canada, a lobby group, said that Trump's Friday statement was "not supported by the facts," noting the US dairy industry ships more American dairy products to Canada than go the other way.
