RCMP say speed was likely a factor of a crash in Gatineau Park that left two people with serious injuries.
They say it happened when a female driver lost control of her vehicle near the MacKenzie King Estate last night.
The vehicle hit a tree head-on and ended up in a ditch.
The driver and one passenger were taken to hospital with serious but non-life threatening injuries.
RCMP say the road was wet at the time and there was thick fog at the time.
An investigation is ongoing.
