OTTAWA, Ont.—Canada’s prime minister Justin Trudeau imposed a retaliatory ten percent tariff on maple sugar and maple syrup this week, one of hundreds of items targeted in a mounting trade war.

“These countermeasures will take effect on July 1, 2018 and will remain in place until the U.S. eliminates trade-restrictive measures against Canadian steel and aluminum products,” Trudeau’s government said in a statement Sunday.  

The U.S. exports approximately $12 million in maple products to the country, according to government statistics.  Most of that syrup originates in Maine.

“I don’t see it will have a huge impact in Maine,” said Lyle Merrifield, president of the Maine Maple Producers Association, during the Maine Maple Mania tour last month.

“There might be only four or five camps that send syrup that way,” he said.

Indeed, most of the syrup made along the Golden Road and other timberland tapping facilities in Maine ship their syrup to U.S. packinghouses.

With the Canadian exchange rate still favorable to Canada, it is unlikely that much more U.S. syrup would head north this year, despite a very short crop in the country.

The exchange rate as of July 2, was $1.32 for every U.S. dollar.
