Yogurt is among Ottawa-proposed list of US imports on which tariffs will be issued. It include chocolate, ketchup, beef, caffeinated roasted coffee, orange juice, maple syrup, salad dressing and soups. Yogurt inclusion seems odd as the total of US-Canada trade on yogurt is only $3 million per year. It seems insignificant if not one fact: all of this $3m sales comes from Wisconsin.
There is a speculation that Canada is about to introduce this measure as a specific message for US Republican Paul Ryan, a House Speaker. As for soup and salad dressings there are rumors that the tariff plan originated after the decision of Campbell Soup to close factory in Canada thus firing 380 of their workers.
