The Victoria Police Department said shortly before 12:30 a.m. PT, witnesses saw a newer-model white sedan speeding at up to 130 km/h on Blanshard Street before it hit a light pole at the Bay Street intersection.
"As officers arrived they could see that the vehicle, a newer model white sedan, had struck a light standard at, what appeared to be, a significant speed," a written statement from the department said.
The front seat passenger, a 20-year-old woman from Saanich, was already dead when police and paramedics arrived.
"Officers noted that the driver appeared intoxicated and, along with witness reports, are investigating alcohol and significant speed as contributing factors in this collision," the Victoria Police Department said.
The driver, who had non-life threatening injuries, was taken to hospital.
Neither the name of the woman nor the name of the driver, a 24-year-old man from Saanich, have been released.
The intersection was closed traffic for several hours.
