OTTAWA — With Donald Trump ramping up his anti-Canada trade rhetoric, Justin Trudeau says the United States — like other countries — subsidizes its dairy and agriculture industries by hundreds of millions, if not billions, of dollars. And the prime minister says he will continue to protect Canada's agriculture producers, including the supply management system, as he tries to engage in "fact-based" conversation with the U.S. administration on a variety of trade irritants. "Let's not pretend we're in a global free market when it comes to agriculture," Trudeau said Thursday in a question-and-answer session with Bloomberg television that preceded Trump's latest trade invective.

And we have a supply management system that works very well here in Canada.... The Americans and other countries chose to subsidize to the tunes of hundreds of millions of dollars, if not billions of dollars, their agriculture industries, including their dairy." He said the U.S. currently enjoys a $400-million dairy surplus with Canada. "So it's not Canada that is a challenge here." Minutes later came the now-familiar sight of Trump in the Oval Office, followed by a pointed attack on Canadian trade practices and the impact on U.S. interests. Farmers being 'put out of business': Trump "Canada, what they've done to our dairy farm workers, is a disgrace. It's a disgrace," Trump said. "Rules, regulations, different things have changed. And our farmers in Wisconsin and New York State are being put out of business." Trump was echoing and amplifying the complaints of Wisconsin and New York governors, who say Canada's decision to create a new lower-priced, classification of milk product has frozen U.S. producers out of the Canadian market. Trudeau acknowledged the concerns of those two states, but said he didn't want to "over-react." It was Trudeau's first comment since Trump first attacked the Canadian dairy industry on Tuesday at an event in Wisconsin.
