The original homesteader on the land, Frank Foster, had planted a grove of trees at the site in 1908.

In 1942, Foster's Grove was purchased by the RM. A bandstand was constructed in 1946 and a cenotaph was erected in 1947. In 1963, the park became Oungre Memorial Regional Park and further developments followed, such as the golf course in 1967, a swimming pool in 1969, the Souris Valley Communiplex in 1984, and an 18-hole mini golf course in 1985.
