Montreal police say the incident took place just before noon today.
Const. Yannick Ouimet said the truck was backing up and smashed a window at the Ponceau daycare, located in a strip mall on Alexis-Carrel Avenue.
"One little boy and a teacher were treated [for shock] as they were really scared," Ouimet said.
He said the only damage to the daycare was the broken window.
Daycare owner Rodney Ruben said it’s a miracle no one was seriously hurt.
