Several people, including two children, are recovering in hospital from serious injuries sustained in a collision on the Sea to Sky Highway on Saturday.
It happened around noon on a stretch of Highway 99 near Daisy Lake, about seven kilometres south of Whistler.
BC Emergency Health Services said six people were taken to hospital, two of them in serious condition.
The exact health condition of the children involved is not yet known.
The agency said six ground ambulances and two air ambulances were deployed to the scene, with one patient airlifted to hospital.
Whistler RCMP tell Global News that a Lamborghini was involved in the crash, as well as a Range Rover and a Toyota Corrolla.
Police say at least one vehicle crossed the centre lane, hitting another vehicle, and then involving a third.
Police have not identified which vehicle is at fault at this point in the investigation, nor have they indicated what caused the first vehicle to cross the centre lane.
The crash prompted the closure of Highway 99 in both directions at Daisy Lake for hours following the collision.
BC Emergency Health Services says one person who was stuck in traffic from the highway closure also required medical attention, and was taken to hospital.
The highway was fully re-opened by about 10 p.m.
