Canada's dairy industry is being put on notice by U-S President Donald Trump.
Trump levelled the threat while unveiling his ``Buy American-Hire American'' executive order at an event in Kenosha, Wisconsin.
Trump told a cheering crowd that he will seek fair trade with all of America's trading partners -- including Canada.
He added that unfair things have happened in Canada to U-S dairy farmers, but didn't mention anything specific.
Finance Minister Bill Morneau will tell this week's meeting of G-20 finance ministers in Washington that Trump's executive order runs contrary to Canada's trading interests.
