It’s a Thursday night out in Windsor and like most bars along the border, shelves at Lefty’s on the O are stocked with both Canadian and American alcohol. The bar's owner Jim Arbour learned Thursday about a potential ban on the sale of American-made alcohol in Ontario.

A senior official in Canada’s most populous province says that Ontario could bar American-made alcohol and restrict electricity to three U.S. states if President-elect Donald Trump imposes sweeping tariffs on all Canadian products.
