A catastrophic collision in Calgary's northeast Saddle Ridge neighbourhood claimed three lives Thursday afternoon when a series of chain-reaction crashes culminated in a violent explosion aboard a transit bus, authorities confirmed Friday.
The incident unfolded just after 1 p.m. in the 800 block of Saddletowne Circle N.E., near the district's fire and police stations. What began as a collision between a Calgary transit bus and a pickup truck spiralled into a multi-vehicle disaster that left emergency responders battling intense flames and 16 people injured.
How the Crash Unfolded
Calgary police laid out a detailed sequence of events leading to the explosion. The northbound transit bus struck a truck travelling in the same direction, forcing the truck into an adjacent lane where it sideswiped an SUV and struck the rear of a box truck.
Simultaneously, the bus continued north and struck the back of a sedan, pushing the vehicle through the intersection into another truck. The bus then collided with a second transit bus—a collision that proved catastrophic.
During impact, the natural gas tanks on the second bus ignited. "A significant fire intensified within seconds," police stated, culminating in an explosion inside the vehicle.
Casualties and Hospital Response
All three fatalities were passengers aboard the second bus. Police have identified the deceased and notified next of kin.
The driver of the first bus sustained life-altering injuries and was transported to hospital. The second bus driver was able to exit the vehicle. Ten people were taken to hospital via ambulance; one remained in life-threatening condition as of Friday. A Calgary police officer sustained minor injuries and is recovering at home.
Other drivers involved in the collision experienced either no injuries or minor trauma.
Investigation Ongoing
Calgary police emphasize that determining the cause remains premature. Speed, impairment, and driver distraction remain under active investigation.
"It's too early to determine whether any of these factors contributed," police said, noting all angles are being examined.
The Calgary Transit Workers Union has called for swift answers, emphasizing that both drivers and the riding public deserve clarity about what happened to restore confidence in the city's transit fleet.
