Whistler RCMP responded to a call just before 7:30 a.m. Sunday about a two-vehicle accident on Highway 99.
Mounties say a car travelling northbound on the highway, just north of Nordic Drive, lost control and slid into the southbound lane.
A minivan travelling southbound collided with the car on the passenger side.
Sgt. Rob Knapton says the driver of the car was airlifted to hospital with critical injuries, while the two occupants of the minivan were shaken, but uninjured.
He says it was snowing at the time but investigators are still determining the cause of the crash.
RCMP were on scene Sunday morning and traffic was reduced to single-lane alternating.
