[3] One version is that a French Canadian National Railway engineer, after slashing through brush and swamp, came to this high and grassy place.

The railway station was built on a small, elevated area of sand and gravel, which had been called "Stony Prairie" by local Indigenous peoples.

Sustained by a nearby deposit of high quality sand, it was the first glass container factory in Western Canada.

Glassblowers from Poland and the United States, supported by local labour, used silica sands to produce bottles for breweries and soft drink companies in Winnipeg.

At its peak, the Manitoba Glass Works employed 350 workers, but because of its inability to compete with Eastern Canadian manufacturers, was purchased in 1913 by a Montreal company and relocated to Redcliff, Alberta.

From the south, Beausejour can be reached by traveling PTH 12 and Provincial Road 215 east into town or by taking PR 302.

Prior to the construction of the Trans-Canada Highway, PTH 44 was the main route from Winnipeg to the Ontario border.

[5] Its location as a main access point to the Whiteshell Provincial Park, a popular cottage region and tourist attraction, allows Beausejour to cater to visitor traffic through the area.

The 2004 Manitoba Scott Tournament of Hearts was won by Lois Fowler (Brandon, Wheat City Curling Club), while the 2016 Scotties Tournament of Hearts was won by Kerri Einarson (East St. Paul Curling Club), with Beausejour's Selena Kaatz playing third.

Beausejour has a humid continental climate influenced by its far inland position in the higher mid-latitudes, resulting in warm and occasionally hot summers and frequently severely cold winters, with January average highs being below −11 °C (12 °F).
