What the borders would look like if the four corners do not meet at a quadripoint.

The four corners of Canadian political subdivisions hypothetically meet at a point near 60°N 102°W.[1][2] These are the provinces of Manitoba and Saskatchewan and the territories of the Northwest Territories (NWT) and Nunavut.[1]

Overview

The four corners area is located between Kasba Lake to the north and Hasbala Lake to the south. It is located by an area of marginal taiga forest, which happens to be the only place in Nunavut which is not Arctic tundra or ice cap.[2] It is hundreds of kilometres from any road or railway, but can be accessed from nearby Kasba Lake Airport/Water Aerodrome as well as from Points North Landing near Wollaston Lake.[3]

The intersection of the boundaries of Manitoba and Saskatchewan with NWT, surveyed before the creation of Nunavut in 1999, is marked by a metre-high aluminium obelisk at Lua error in package.lua at line 80: module 'strict' not found. (NAD83),[4] inscribed to say it was erected in 1962.[3] This location is about 400 metres (1,300 ft) away from the meridian of 102°W.[5] On the top of the obilisk there is a disc warning of five years imprisonment for removing or destroying the monument.[3]

The establishment of Nunavut in 1999 led to the creation of Canada's only quadripoint at this location.[2] In the legal definition of Nunavut, its border is specified as "Commencing at the intersection of 60°00'N latitude with 102°00'W longitude, being the intersection of the Manitoba, Northwest Territories and Saskatchewan borders".[6][7] Since the intersection does not lie exactly at those coordinates, the laws are not perfectly clear about whether or not the Nunavut–NWT boundary, which has not been completely surveyed,[8] is to meet the others in a quadripoint. Surveys began in 2011.[9][10]
