The Parks Canada Agency was established as a separate service entity in 1998, and falls under the responsibility of Environment Canada . Before 2003, Parks Canada (under various names) fell under the jurisdiction of the Department of Canadian Heritage , where it had been since 1994. From 1979 to 1994, Parks Canada was part of the Department of Environment, and before it was part of the Department of Indian and Northern Affairs (1966 to 1978), and the Department of the Interior.  With the organizational shifts and political leadership in Canada, the priorities of Parks Canada have shifted over the years more towards conservation and away from development.  Starting in the 1960s, Parks Canada has also moved to decentralize its operations.
