The accident happened at the Westboro station in a neighborhood west of downtown Ottawa.
The local police reported that at least three people died after a bus crashed into a bus shelter at Westboro Station in Ottawa.
"Something led us to having to arrest the individual and take them to the station", Bordeleau said. It plowed along a station platform and into the overhanging roof of the transit shelter, which carved deep into the vehicle's upper level and crushed a number of seats.
One woman who could walk was helped off a bus by two first responders, one supporting each of her arms.
She told Global News that what chilled her the most is that she'd been sitting in an identical double-decker bus as she passed, in the same upper-right section that saw the most damage from the impact. He said police were still investigating the cause of the crash.
23 people were injured, 14 had been placed in a life-threatening condition to the hospital, said a spokesman for the rescue workers.
The bus was nearly at its 90-passenger capacity when the crash occurred, police say.
The Ottawa Paramedic Service said Friday there are multiple critical injuries, though no immediate reports of fatalities.
Graham said police will be flying drones today to take aerial shots and they hope to clear the scene, and the accompanying roadblocks, by the end of the day.
This is the second deadly collision involving a double-decker bus in Ottawa in the last six years. "The front of the bus was essentially cut off and or demolished and firefighters were working to cut away the windows of the top floor of the bus". I felt like vomiting a couple of times.
"My first thoughts are with those who have been injured and their families". In that case, an investigation found that the cause was a combination of excessive speed, a hard curve before the tracks and driver distraction from video monitors showing the upper deck.
