One person is dead and two were taken to hospital after a two-car crash near Steveston Highway and No. 3 Road.
The crash happened just after 12:30 p.m. Sunday, about one block east of the major intersection at Roseland Gate.
Richmond RCMP called in the road safety unit and ICARS to assist in the investigation, but it's believed that one of the vehicles may have crossed the centre line, possibly as the result of a medical incident.
The investigation is continuing and it's not yet clear whether the surviving driver will face charges or not.
The area around the intersection was closed for several hours Sunday afternoon to allow police to comb the scene.
Anyone who witnessed the crash is asked to contact Richmond RCMP at 604-278-1212.
