Five people were killed when two small aircraft collided in mid-air and crashed in Saskatchewan on Saturday.

The RCMP confirmed the death toll as investigators surveyed the crash site, which is near St. Brieux, Sask.

Officials were alerted Saturday morning after plane wreckage was discovered near the small community, located about 180 kilometres northeast of Saskatoon, said Capt. Robert Landriault at the Joint Rescue Co-ordination Centre in Trenton, Ont.

One of the planes was a Piper PA-28, which was flying from Calgary to St. Brieux. Two men and a young male were onboard.

The other aircraft was a Lake Buccaneer amphibious plane, which was headed from Regina to La Ronge. A man and a woman were on that plane.

The wreckage was found submerged in a small body of water, investigators said.

Chris Krepski, a spokesman for the Transportation Safety Board of Canada, said the agency has dispatched investigators to the scene.
