NIAGARA FALLS, ON - A teacher from a Catholic high school has been charged with impaired driving after being involved in an accident while she was driving students in a van.

Frances MacDonald, 46, of Niagara Falls, was charged by the Ontario Provincial Police Thursday in Haldimand County with impaired driving causing bodily harm and driving with more than the legal limit of alcohol.

The OPP said MacDonald was returning to Niagara from a school trip around 3:50 p.m. Thursday when the 2012 Dodge van she was driving collided with the back of a Yamaha motorcycle.

The driver of the motorcycle, a 57-year-old from Hamilton, was taken to a hospital in Hagersville to be treated for non-life-threatening injuries.

Neither MacDonald nor the students, who range in age from 15 to 18 years old, were injured in the accident.

John Crocco, the director of education for the Niagara Catholic District School Board, said he was aware of the accident.

He said MacDonald and the students were returning from a trip at a fishing tournament near St. Thomas.

"All of the students who took part in the trip are safe," he said. "We continue to investigate as a school board. As we conduct our investigation, we aren't at liberty to provide any additional information at this time."

Crocco wouldn't say whether or not MacDonald had been suspended or otherwise disciplined by the board.

"I have no comment," he said when asked about her employment status.

The OPP said MacDonald will appear in provincial court in Cayuga at a later date.
