It sounds like something straight out of a sitcom, but this one is real, and it's worrisome.
According to Toronto Police, a 27 year old man walked into at least 5 schools, pretending to be a teacher or an educational assistant.
Bayol Avah has been charged with 5 counts of personation to gain advantage.
Cops say he pretended to be a teacher at Inglewood Heights Junior Public School, H. A. Halbert Junior Public School, Ionview Public School, Birchmount Park Collegiate Institute, and Centennial Road Junior Public School.
He also allegedly pretended to be a special needs assistant.
He was never employed by the Toronto District School Board.
The alleged incidents happened between April 1st and June 1st of this year.
Toronto Police Constable David Hopkinson says there aren't any other charges "because the evidence didn't support them."
Hopkinson credits the schools for first alerting police about the alleged imposter.
"If you talk the talk and walk the walk, a lot of the times you'll get away with something like this. It was due to the schools coming forward and doing their due diligence with regards to this man."
But how could something like this happen?
The Toronto District School Board is trying to find out.
"This is not a case of a random person walking into a school. To do something like this you need very specific information to do this. So this really is an isolated incident." said TDSB spokesperson Ryan Bird.
But Bird says "It's never happened before so we're now reviewing how we do things to see if there are any lessons to be learned. And we'll adjust things as needed."
