A First Nation youth group outing to play laser tag ended in tragedy when two vehicles collided on a rural Ontario road, killing two young girls and one driver.

Four others were rushed to hospitals in critical condition.

The crash occurred around 9 p.m. Wednesday on Highway 6 near Caledonia, Ont., located about 94 kilometres southwest of Toronto.

A car driven by a 21-year-old man from Six Nations of the Grand River First Nation was travelling north on Highway 6 when it crossed the centre line and collided with a southbound passenger van carrying a group of people from the Mississaugas of the New Credit First Nation.

As a result of the impact, the van rolled and landed in a ditch.

The driver of the car, Wyatt Martin, along with van passengers Grace King, 12, and Waagosh Secord, 14, were pronounced dead at the scene.

The 27-year-old driver of the van and his remaining young passengers survived the crash but some of them sustained serious injuries.

Ontario Provincial Police Const. Rob McClair said police are looking into whether alcohol was a contributing factor.

Mississaugas of the New Credit First Nation Chief Stacey Laforme told reporters Thursday that a youth group was returning home from a laser tag outing in Hamilton, Ont., when the crash occurred.

The youth were travelling in two separate vans, he said. The second van was not involved in the collision.

The elementary school on the First Nation was closed Thursday. Counsellors are attending the local community centre, which is open to anyone who needs to talk.

“We are trying to support each other,” Laforme said, adding that Mississaugas of the New Credit is a very close-knit community. “They are all our children,” he said.

Some members of the community gathered at a local church to pray for those who passed.

A woman who lives near the site of the crash, identified only as Karen, told CP24 that she heard “what sounded like a bomb” Wednesday night.

She ran outside and saw the smashed vehicles, then called 911. She heard children screaming from the van, “and then unfortunately that stopped,” she said.
