On June 24, 1909, a committee submitted a petition to organize 7 full and 3 partial townships. This petition was granted on July 26, 1909. The Municipal Committee named John J. Heinrich of Aberdeen as their representative. The petition was signed by 58 persons. The petition was granted and a vote taken on July 26, 1909; 120 in favor and 6 opposed. The Rural Municipality was established by the Order of Honourable A.P. McNab, Municipal Commissioner, December 13,1909. Since then one township was annexed by the R.M. of Corman Park. During the period of 1915 -1919, considerable road improvements and construction have taken place because of the new popularity of automobiles. Roads remained the major concerns for the municipality for many years to come. Today, the R.M. of Aberdeen maintains over 340 miles of road in the summer and over 200 miles of road in the winter. Highways # 41 and # 27 run through the R.M.
The South Eastern border of the R.M. of Aberdeen No. 373 is just five miles east of Saskatoon, the largest city in Saskatchewan, where we have the country residential areas of Strawberry Hills, Strawberry Ridge, Valley View Heights, Cherry Hills Estates, Bergheim Estates, The Meadows, Prairie Rose Estates, and Mission Ridge Estates. The Hamlet of Edenburg lies three miles north east of the Town of Aberdeen which is twenty minutes north east of Saskatoon.
The R.M. of Aberdeen is the home of the Fish Creek Historical Site where a monument sits at General Middleton’s Camp. The battlefield where Middleton fought the Riel troops during the Riel Rebellion is located one mile south east of the camp where two additional monuments to the historical battle have been placed. The Clarkboro Ferry is located close to the Historical Clarke’s Crossing where Middleton’s troops crossed the South Saskatchewan on their way to the Fish Creek Battle from North Battleford. A monument to Clarke’s Crossing has been placed on Edenburg road, south west of the Town of Aberdeen.
Within the boundaries of the R.M. of Aberdeen reside three major business. Louis Dreyfus High Throughput Grain Terminal lies along the CNR line. Horizon Seed Processors which processes pulse crops and are shipped throughout the world is also located along the CNR line. Hold On Industries is a manufacturer of plastic water tanks and floating docks among other things. Agriculture is the leading industry in the region.
The municipal office is located within the Town of Aberdeen which is located along Highway 41 in the center of the municipality. The municipality provides a library, transfer station, fire fighting, first responders, and recreation facilities through agreements with the Town of Aberdeen.
