Madeleine Noiseux was waiting for a bus at the corner of Gaétan-Boucher Boulevard and Davis Boulevard when the accident happened, steps from where she was.
An unmarked car driven by a Sûreté du Québec officer slammed into a car transporting two young children as it made a left turn.
Noiseux said it was clear to her the car driven by the officer was driving too fast. She believes the car transporting the young boy would have safely made the turn and cleared the intersection had the investigator’s car not been travelling so fast.
"I don't think it's fair. You can't blame the dad because the other guy was going so fast," said Noiseux. "It's not normal to go so fast."
The investigator was driving at 122 km/h in a 50 km/h zone moments before the collision.
Police investigating the accident interviewed Noiseux the day after it happened.
Noiseux said when she heard the officer would not be facing charges she was shocked.
The crown prosecutor's office explained Friday why it chose not to charge the officer.
The Director of Criminal and Penal Prosecutions, RenéVerret, said all evidence in the case was taken into consideration to not charge the officer.
He said that included a statement from the father who told investigators he should not have turned left at the time and he did not have the right of way.
