U.S.-Canada Environmental Cooperation

city of Cornwall

The United States and Canada have one of the world's oldest and most effective environmental partnerships. The U.S.-Canada border includes four of the five Great Lakes, as well as many rivers and lakes, major airsheds, and migratory routes for wildlife species. In addition, there are many U.S. Native American Tribes and Canadian First Nations residents whose culture spans the border.

The extensive border and the considerable and diverse geography of the ecosystems shared by the two countries requires close cooperation among many U.S. states, Canadian provinces, U.S. Tribes, First Nations, and local and federal governments. The two federal governments have implemented over 40 international agreements for the management and protection of environmental quality and ecosystems in the border area and there are over 100 additional such agreements between U.S. states and Canadian provinces. The two countries also share policies, programs, and goals to prevent and control pollution and to ensure sound policies and practices to protect and restore the many shared ecosystems.
