OTTAWA — With only days before the first round of tariffs take effect, Canada’s allies in Washington, D.C. are pushing for U.S. President Donald Trump to permanently rescind the measures, arguing a trade war would cause economic harm on both sides of the border.

In an interview with the National Post, U.S. Congressman Tim Kennedy, a Democrat in the Buffalo-Niagara region, said he and dozens of other representatives are fighting to get Trump to reverse his decision to impose tariffs on their northern neighbour.
