Names of pan-Canadian significance

For most geographical names there is only one official form. However, certain geographical names require presentation in both official languages of Canada on federal maps.

Pan-Canadian names: 81 large and well-known Canadian features and areas were designated in Treasury Board Circular 1983-58 (e.g., Lake Winnipeg / Lac Winnipeg).  In October 2008, the Geographical Names Board of Canada appoved a new list which incorporates changes due to legislation since that time;
