Settled in the 1880s and named after the storekeeper Edmund Boucher, Boucherville was a hamlet that housed a post office. This is where Du Vernet picked up his first letter from home, on July 21. The post office in Boucherville was the post office for all of the Rainy River.
Boucherville is also where Du Vernet and Jeremiah Johnston met Charlie, their Ojibwe canoe guide, on July 14. The town seems to have been a popular hub on the river. For example, Du Vernet mentions that Jeremiah Johnston had to travel to Boucherville to marry a couple on July 19th. In 1901, once the Canadian Northern Railway connected its eastern and western tracks about two miles north of Boucherville, its inhabitants moved to establish the new town of Stratton. While Boucherville no longer exists, a road in Stratton is named after the small town.
