Moosomin is a town in southern Saskatchewan founded in 1882. It is 20 kilometres west of the provincial boundary between Saskatchewan and Manitoba. With the arrival of the Canadian Pacific Railway in 1882, Moosomin was established as the first Saskatchewan community on "steel". Originally known as "siding No. 4" and the "Moosomin Station", businesses began to establish and by 1884 the community had grown to include five general stores, five hotels, two livery stables, two blacksmiths, a doctor, a lawyer, butcher, and one printer, among other businesses. Moosomin was incorporated as a town in November 1887. R. D. McNaughton was the first merchant to arrive in Moosomin. He founded the R. D. McNaughton Company, a general store operation that played a vital role in early settlement.
