RCMP say they received several calls about shots being fired at about 2:30 a.m. on Thursday.
Officers say they arrived to find three men at a home in the same area, all suffering from gunshot wounds.
Mounties say one of the men has life-threatening injuries while the other two were not as seriously hurt.
RCMP say the two men with lesser injuries have not been co-operative, and all three are known to police.
Investigators say they don't know yet if it was a drive-by shooting and that none of the victims lives at the home where they were found.
