Manitoba was created by the proclamation of the Manitoba Act on 15 July 1870. Near this site was the original western boundary of a province that measured 130 miles east to west and 110 miles south to north with an area of 13,924 square miles. Its size and shape gave it the nickname “The Postage Stamp Province”. The boundaries were extended in 1881 and 1912, in the latter case to the present ones. The Boundary Commission in 1873 and the North West Mounted Police in 1874 crossed the west boundary at this point as they moved into what was then known as the North West Territories.
This plaque, located just off Highway #3 on the west side of a local road in the Municipality of Louise, was erected by the Boundary Trail Heritage Region. The 99th line of longitude that marked the western boundary of Manitoba is actually located 0.73 kilometers east of the plaque.
