Within three hours on Monday, Vancouver police and the Langley RCMP called the Independent Investigations Office to take over fatalities involving officers.
Ten members of the IIO are now investigating a fatal shooting involving a Vancouver officer confronted by a knife-wielding man in the northeast part of the city.
Police say the officer was investigating reports of windows being smashed at about 8:15 p.m. Monday when the shooting occurred.
The man was taken to hospital, but he didn't survive his injuries.
Few other details were released.
"IIO investigators will return to the scene (Tuesday) and will gather evidence and continue with interviewing any involved officers and witnesses," the office said in a news release.
Hours earlier Monday, IIO members were called when Mounties in Langley tried to stop a speeding vehicle in the suburb south of Vancouver.
The IIO said police were conducting an automated licence reader enforcement project when they attempted to stop a vehicle.
Police said the driver raced off and the vehicle collided with another car, killing the second driver.
"Approximately three minutes later, a collision occurred involving the subject vehicle and two other vehicles," said an IIO bulletin. "The male driver of one of those vehicles was deceased at the scene."
The driver is in custody.
Since the Independent Investigations Office opened in early September, civilian investigators have responded to eight cases around British Columbia related to RCMP or municipal police officers involved in death or serious injury incidents.
