The RM was incorporated on January 1, 2015 via the amalgamation of the
RM of Winchester and the
Town of Deloraine. It was formed as a requirement of
The Municipal Amalgamations Act, which required that municipalities with a population less than 1,000 amalgamate with one or more neighbouring municipalities by 2015. The Government of Manitoba initiated these amalgamations in order for municipalities to meet the 1997 minimum population requirement of 1,000 to incorporate a municipality. == Communities ==
