GeoCarta notes the news that a boundary dispute between the Canadian provinces of Quebec and Newfoundland and Labrador has flared up over Quebec wildlife maps that show part of Labrador as belonging to Quebec.
This is not new. The Quebec-Labrador boundary has been in dispute since 1902, and a formal Privy Council decision in 1927, setting the present boundary, has not been accepted by everyone. Indeed, Quebec’s official maps frequently show two boundaries to southern Labrador, their unilateral boundary and the real boundary, labelled “Tracé de 1927 du Conseil privé (non définitif),” despite the fact that no one other than the province disputes it, and past provincial commissions have agreed that nothing could be done about it. (Then again, Quebec separatists’ maps include all of Labrador.) I live in Quebec, so I know.
