Parks Canada
Parks Canada was established on May 19, 1911, as the Dominion Parks Branch under the Department of the Interior, becoming the world's first national park service. Since its creation, its name has changed, known variously as the Dominion Parks Branch, National Parks Branch, Parks Canada, Environment Canada – Parks Branch, and the Canadian Parks Service, before a return to Parks Canada in 1998. The service's activities are regulated under legislation such as the "Canada National Parks Act", and the "Parks Canada Agency Act", which established the current legal incorporation of the agency in 1998.
