Dominion Land Survey
The Dominion Land Survey is the method used to divide most of western Canada into one-square-mile sections for agricultural and other purposes. It is based on the Public Land Survey System used in the United States, but has several differences. The DLS is the dominant survey method in the Prairie Provinces, but it is also used in British Columbia along the Railway Belt (near the main line of the Canadian Pacific Railway), and in the Peace River Block in the northeast of the province. The survey was begun July 10, 1871, shortly after Manitoba and the North-West Territories became part of the Dominion. Covering about 800 000 square kilometres, the survey system and its terminology is deeply ingrained in the rural culture of the Prairies.The most important north–south lines of the survey are the meridians:
- The First (or Principal) Meridian at 97°27′28.41″ west.
- The Second Meridian at 102° west, which forms the northern part of the Manitoba–Saskatchewan boundary.
- The Third Meridian at 106° west, near Moose Jaw and Prince Albert, Saskatchewan.
- The Fourth Meridian at 110° west, which forms the Saskatchewan–Alberta boundary and bisects Lloydminster.
- The Fifth Meridian at 114° west, which runs through Calgary, Alberta (Barlow Trail is built mostly on the meridian) and near Stony Plain, Alberta.
- The Sixth Meridian at 118° west, near Grande Prairie, Alberta and Revelstoke, British Columbia.
- The Seventh Meridian at 122° west, between Hope and Vancouver, British Columbia.
Starting at each intersection of a meridian and a base line and working west (also working east of the First Meridian), rectangular townships are surveyed, which are about six miles in both north–south and east–west extent. There are two tiers of townships to north and two tiers the south of each base line.
Because the east and west edges of townships (range lines) are meridians of longitude, they converge towards the north pole. Therefore, the north edge of every township is slightly shorter than the south. Halfway between two base lines, the short north boundaries of townships surveyed from the base line to the south abut the long south boundaries of townships surveyed from the base line to the north. The east and west boundaries of these townships therefore do not align, and north–south roads that follow the survey system have to jog to the east or west. These east–west lines halfway between base lines are called correction lines.
Townships are designated by their township number and range number. Township 1 is the first north of the First Base Line, and the numbers increase to the north. Range numbers recommence with Range 1 at each meridian and increase to the west (and also to the east of First Meridian). On maps, township numbers are marked in Arabic numerals, but range numbers are often marked in Roman numerals; however, in other contexts Arabic numerals are used for both. Individual townships are designated such as "Township 52 Range 25 west of the Fourth Meridian," abbreviated "52-25-W4." In Manitoba, the First Meridian is the only one used, so the abbreviations are even more terse, e.g., "3-1-W" and "24-2-E."
Every township is divided into thirty-six sections, each about one-mile square. Sections are numbered within townships as follows (north at top):
31 32 33 34 35 36 30 29 28 27 26 25 19 20 21 22 23 24 18 17 16 15 14 13 7 8 9 10 11 12 6 5 4 3 2 1In turn, each section is divided into four quarter sections: southeast, southwest, northwest and northeast. The full legal description of a particular quarter section is "the Northeast Quarter of Section 20, Township 52, Range 25 west of the Fourth Meridian", abbreviated "NE-20-52-25-W4."
Between certain sections of a township run road allowances, on which a road may or may not have been built. The road allowances add to the size of the township (they do not cut down the size of the sections): this is the reason base lines are not exactly 24 miles apart. In townships surveyed from 1871 to 1880 (most of southern Manitoba, part of southeastern Saskatchewan and a small region near Prince Albert, Saskatchewan), there are 99-foot-wide road allowances surrounding every section. In townships surveyed from 1881 to the present, road allowances are reduced both in width and in number. They are 66 feet wide (one chain) and run north–south between all sections; however, there are only three east–west road allowances in each township, on the north side of sections 7 to 12, 19 to 24 and 31 to 36.
Certain sections of townships were reserved for special purposes:
- Section 8 and three-quarters of Section 26 originally belonged to the Hudson's Bay Company, as part of the deal that transferred Rupert's Land and the North-Western Territory from the Bay to the Dominion. According the deal, the Bay retained 5% of the land. The Bay sold all these sections long ago, but they are often locally called "the Bay section" today.
- The odd-numbered sections (except 11 and 29) were reserved for railway land-grants. The Prairies could not be settled without railways, so the Dominion government habitually granted large tracts of land to railway companies as an incentive to build lines. Notably, the Canadian Pacific Railway was granted 101 000 square kilometres. These are colloquially called CPR sections regardless of the railway they were originally granted to.
- Sections 11 and 29 were school sections. When school boards were formed, they gained title to these sections, which were then sold to fund the initial construction of schools. The rural school buildings were often as not located on school sections.
- The remaining sections were available as homesteads — the Dominion government's plan for settling the West. A homesteader paid a $10 deposit and was assigned a quarter section of his choice. If after three years he had 120 000 square metres of crop and had built a house (often just a sod house), he regained his deposit and title to the quarter. Homesteads were available as late as the 1950s, but the bulk of the settlement of the Prairies was 1885 to 1914.
