Canada is calling for its continental trade deal with the U.S. and Mexico to be renewed for another 16 years, even as talks with the U.S. remain frozen and President Donald Trump is renewing his annexation threats.

In a letter to his U.S. and Mexican counterparts on Tuesday, Intergovernmental Affairs Minister Dominic LeBlanc said “Canada recommends renewal” of the U.S.-Mexico-Canada Agreement ahead of a July 1 deadline by which the countries must decide whether to re-up the deal or renegotiate it.

Mr. LeBlanc is scheduled later on Tuesday to meet in Washington with U.S. Trade Representative Jamieson Greer, who has made clear that the U.S. intends to renegotiate key aspects of the agreement.

“The Agreement is highly beneficial to each of our countries and to the integrated North American economy,” Mr. LeBlanc wrote. He added, however, that Canada recognizes that the other countries can demand changes and said it will he “essential” to negotiate over Mr. Trump’s tariffs on Canadian autos, steel, aluminum and lumber.
