A father and his two sons, along with another young boy, were killed in a plane crash near their home community of Waskada on Sunday evening.
It's believed all three boys were younger than 12 years old, said two residents of the community in southwestern Manitoba.
RCMP have confirmed there were fatalities but would not say how many were on board the Cessna plane until next of kin were notified.
The plane was found about 7 p.m. with the help of Canadian Forces search and rescue technicians, according to RCMP from the Killarney detachment.
Police were at the scene Sunday night investigating with the help of the Transportation Safety Board and the RCMP forensics unit.
The crash scene is about 10 kilometres north of Waskada.
Late Sunday night, Waskada Mayor Gary Williams said news of the horrific crash was just beginning to spread.
"It's going to be tough," he said. "It's Sunday night, but once Monday comes and people start their normal day, their normal routines, it's going to be a real shock.
"(The boys) went to a small school, and every kid sees the other kids every day," he said, adding the family is well known in the community.
Waskada is located 300 kilometres southwest of Winnipeg near the Saskatchewan border.
