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 last new province, Newfoundland, was brought into the country in 1949 by an act of the British Parliament before the 1982 patriation of the constitution.
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.
In 1966, a committee of mayors from the region, comprising Max Silverman of Sudbury, G. W. Maybury of Kapuskasing, Ernest Reid of Fort William, Leo Del Villano of Timmins, Merle Dickerson of North Bay and Leo Foucault of Espanola, formed to study the feasibility of Northern Ontario forming a new province.
