Fort de la Corne, Trading post and national historic site in Kinistino, Canada.

Fort de la Corne is a former trading post on the Saskatchewan River in the Canadian province of Saskatchewan, now marked by a commemorative plaque in Memorial Park in Kinistino. The plaque stands at the corner of Main Street and Dixon Road, close to the riverbank where trading once took place.

Louis de la Corne established the post in 1753 under the name Fort Saint-Louis, making it the westernmost French outpost in the region at the time. Around 1760, the British took control as the balance of power between European forces in North America shifted.

The trading post served as a meeting place where French settlers and Indigenous peoples exchanged goods and knowledge. These interactions shaped the early relationships between European newcomers and local communities in the region.

The site is in a public park and can be visited at any time without any prior arrangement. After reading the plaque, it is worth walking toward the nearby riverbank to get a sense of where the original post was located.

In the 2000s De Beers and ShoreGold explored the Fort à la Corne kimberlite field for diamonds. A Rio Tinto and Star Diamond Corporation partnership carried on through the 2010s and in early 2021 reported finds of commercial-grade diamonds; whether mining would proceed was still undecided.
