A driver has been charged following a fatal crash into a Richmond Hill daycare on Wednesday, police say.

In a statement issued Thursday, York Regional Police said a man has been charged with one count of dangerous operation causing death and two counts of dangerous operation causing bodily harm.

A one and a half-year-old boy was killed and six other children injured after a vehicle drove into First Roots Early Education Academy around 3 p.m. Wednesday. 

One child remains in critical condition and the other victims have non-life-threatening injuries as of Thursday morning, said York police. 

There were 96 children in the building at the time of the crash, said police. 

Three adult staff members were also hurt.

A man in his 70s was arrested at the scene. Investigators said Wednesday they do not believe the crash was intentional, but did not indicate what triggered the incident during the afternoon pickup time.

A full-size Hyundai electric vehicle was pulled from the building and loaded onto a tow truck on Wednesday evening, and showed little visible damage aside from a dangling licence plate.

Richmond Hill, Ont., daycare crash not believed to be deliberate, police say

A child is dead, several others are injured and a man in his 70s is in custody after a vehicle drove into a daycare in Richmond Hill, Ont., on Wednesday, police said at a news conference. Police say the investigation is ongoing, but they don’t believe it was a deliberate act.

Parents were very shaken up in the chaos after the crash, Richmond Hill Mayor David West said on CBC Radio’s Metro Morning Thursday. 

West said the city is in mourning after the incident, and he will speak to victims’ families and other parents in the days ahead. 

“To imagine the situation that these people are in is just unthinkable, even today after this has had some time to sink in,” he said. 

“We are a strong community. We will stand together and do what we need to help everyone get through this.”

The car crashed into the daycare from the parking lot at the back of the building, West said.

Police say the investigation is still ongoing.Â
