List of proposed provinces and territories of Canada

Since Canadian Confederation in 1867, there have been several proposals for new Canadian provinces and territories. Since 1982, the current Constitution of Canada requires an amendment ratified by seven provincial legislatures representing at least half of the national population for the creation of a new province while the creation of a new territory requires only an act of Parliament. Because opening up the constitution to amendment could entice provinces to demand other changes too in exchange for such support, this is seen to be a politically unfeasible option. The newest province, Newfoundland and Labrador, joined Canada in 1949 by an act of the British Parliament before the 1982 patriation of the constitution.
Movements within Canada.
There have been movements to redistrict existing land in order to create new provinces and territories within Canada. In late 2004, Prime Minister Paul Martin surprised some observers by expressing his personal support for all three territories gaining provincial status "eventually". He cited their importance to the country as a whole and the ongoing need to assert sovereignty in the Arctic, particularly as global warming could make that region more open to exploitation leading to more complex international waters disputes.
Movements outside of Canada.
British overseas territories.
In 1905 British M.P. Ian Malcolm suggested in the British House of Commons that the U.K. might benefit from transferring one or some of the West Indies isles to Canada for national defence.
Robert Borden and his delegation to the Paris Peace Conference of 1919 discussed transferring parts of the West Indies as territories, sub-dominions or League of Nations mandates, including the possibility of exchanging certain ones to the United States for the Alaska panhandle.

Other.
Two small border exclaves of the United States have also been the subject of proposals to secede from the United States and join Canada. Neither would become its own standalone province or territory if it joined Canada, however, but rather both would simply be added to the existing provinces that they adjoin.
