A devastating late-night collision on Calgary’s Stoney Trail has claimed the lives of four people and left four others injured after a vehicle was reportedly travelling in the wrong direction.
According to Calgary police, the crash occurred at approximately 11 p.m. Sunday on the northbound lanes of Stoney Trail near 90th Avenue S.W. Investigators say a 30-year-old man driving a 2011 Mercedes-Benz C350 was travelling southbound in the northbound lanes when it collided head-on with a 2016 Subaru Impreza driven by a 43-year-old man.
The force of the collision caused both vehicles to catch fire. A 2016 Chevrolet Equinox, driven by a 52-year-old woman, subsequently struck the burning Mercedes.
Police confirmed that three people travelling in the Mercedes—the driver, an adult woman and a child—died at the scene. The 43-year-old Subaru driver, who was the vehicle’s only occupant, also died.
The Chevrolet driver and three young passengers were taken to hospital for treatment. One of the young passengers suffered serious but non-life-threatening injuries, while the other injured people were reported to have less severe injuries.
Calgary firefighters responded to the scene and found two of the vehicles heavily engulfed in flames. Crews worked to extinguish the fires while emergency personnel assisted those who survived the collision.
Investigation Continues
Police are investigating the circumstances that led to the Mercedes travelling in the wrong direction. Investigators are examining whether speed, impairment or other factors may have contributed to the crash.
The investigation remains ongoing, and authorities are expected to review available evidence, including vehicle information, witness accounts and other relevant evidence, as they work to establish the full sequence of events.
The fatal collision has resulted in a major loss of life and injuries to several others, leaving families and the wider Calgary community grieving. Authorities continue to urge motorists to exercise caution and remain attentive while travelling on major highways, particularly at night.
