In 1898, the post office name changed from Mossy River to Winnipegosis,[6] when it joined other buildings moved to the new townsite.

[7] That year, the community possessed 2 hotels, 2 boarding houses, 3 general stores, a butcher, a blacksmith, a 30-man sawmill, and 2 larger fish trading companies (North West Fish Co. and The Armstrong Trading Co, subsidiary of Booth Fisheries Co.).

[16][17] In early 1906, Joseph Grenon Jr. began a mink ranch across the river, from where he sold the animals and furs to Moncton, New Brunswick.

The community also has a Royal Canadian Mounted Police detachment, a volunteer fire department, and ambulance service.
