Canada says it will be tough challenge to get trade deal ratified by U.S.

Canadian Deputy Prime Minister Chrystia Freeland on Thursday said it would be a "tough challenge" to get a new three-nation continental trade agreement ratified by the United States.

The United States-Mexico-Canada Agreement was signed in November 2018 but formal U.S. approval has been held up by Democratic lawmakers pressing for changes, including steps on drug protections.
