The Surete du Quebec is investigating the driving behaviour of one or both drivers following a school bus collision with a truck on Hwy. 640 Thursday morning.

Thirty-three children plus staff were headed to the YCC (Harry Bronfman Y Country Camp) summer camp aboard the bus, with ages ranging from 7 to 14 years old.

The children aboard the bus were more shaken up than injured.

Victim Ariel Nathan said the scene was a little scary.

“(The driver) hit the truck and flew into the grass,” she said.

Witness Jon Gould stopped his car to help.

"There was a bus full of screaming kids, panicking and they needed to get out of the bus," he said. "I wasn't sure from a distance if the bus was sitting in water, if there was a fire risk, so I went to one of the windows, the emergency exit, and we started pulling kids out of the bus."

Up to 10 people suffered minor injuries.

The collision occurred in the eastbound lanes, near the ramp to Highway 15 north, at 9 a.m. 

The ramp was closed while police investigate the cause of the crash. 

Other than the bus driver, Gould said he didn't see any adults but did see several camp counsellors and staff members. 

"I saw from first glance six or seven kids who sustained injuries, probably from hitting the seats in front of them. A lot of bleeding noses and fat lips," he said.

Gould said another school bus was dispatched to pick up the kids. All the injured were taken to St-Eustache Hospital for evaluation as a precaution. Hospital officials said several of the injured have already been released. 

“We're very fortunate that everybody is doing well and we look forward to getting them up to camp,” said YCC executive director Marla Gold.

Parent Dina Nathan said she was relieved the injuries weren’t more serious.

“Thank God the kids are okay. That's all that matters. It was just shocking,” she said.

The children will now head up to camp where additional support is being offered if needed.

“We have our own people asking them questions to make sure they feel good and they are not in shock,” said YCC president Alvin Fagen.
