A 26-year-old man was saved by friends after he crashed his personal watercraft into an anchored boat, throwing him into the Ottawa River in Woodlawn, Ont., west of Ottawa.

Ottawa paramedics say the crash happened about 75 metres from shore at about 11:45 p.m. Saturday. The closest intersection to the crash was Lane Street and Bayview Drive, paramedics said.

Paramedics and firefighters said the man was riding the watercraft when he struck a parked boat. The crash tossed the man into the water and he suffered a concussion, paramedics added.

The quick actions by the man's friends likely saved his life, as they swam out to pull him from under the water. Firefighters then arrived and pulled the man to shore.

Paramedics treated the victim for head injuries and firefighters helped place him on a spinal board before he was taken to hospital.

He arrived there in serious, but stable condition.

Ottawa police are investigating.

This crash comes on the Canada Day long weekend, as Ontario Provincial Police warn the public about boat safety.
