Three more ministers from Justin Trudeau's cabinet will be in the United States this week, as the federal government continues to lobby American leaders and lawmakers about the importance of maintaining unfettered trade between the two countries.

With U.S. President Donald Trump hoping to renegotiate the North American Free Trade Agreement and others suggesting the imposition of a border adjustment tax on imports to the United States, the Trudeau government has been at pains to stress how the American economy benefits from access to Canadian companies and consumers.

That effort has expanded beyond the Trudeau cabinet's dealings with its American counterparts to include outreach at the state and municipal levels, with Canadian ministers targeting a list of 11 key states.
