The Rural Municipality of Turtle Mountain area is rich in history and tradition. In the late 1800s, the Boundary Commission Trail ran through the southern part of the municipality. Northwest Mounted Police used the trail, as they traveled west to the Rockies in an effort to tame the prairies. Prior to this time, the area was home to many Native People, as well as, hunters and trappers taking part in the fur trade. The RM of Turtle Mountain was incorporated in 1882.

 

The Town of Killarney was officially incorporated in 1906. An Irish land surveyor named John Sidney O'Brien, named Killarney Lake (before that, it was called Oak lake by the aboriginal people) after the Lakes of Killarney, in Ireland. Legend has it that as he sat on the shore of the lake, homesick for his native home, he took a bottle of "Good Irish" from his pack and pouring it into the lake christened it Killarney
