The Port of Vancouver is the largest port in Canada and the fourth largest in North America by tonnes of cargo, facilitating trade between Canada and more than 170 world economies. The port is managed by the Vancouver Fraser Port Authority, which was created in 2008 as an amalgamation of the former Port of Vancouver, the North Fraser Port Authority, and the Fraser River Port Authority. It is the principal authority for shipping and port-related land and sea use in the Metro Vancouver region.
