“What a terrible tragedy this morning in Laval,” Quebec Premier Francois Legault tweeted.
“There is nothing worse than being afraid for your child. I am thinking of the children, the parents and the employees,” he added.
“As a father, I am shaken,” he said later at a press conference.
“I can understand the anguish that the parents are going through,” he said.
“I am shocked by this news. The investigation continues to understand this tragic series of events,” tweeted Stephane Boyer, the mayor of Laval.
“All of my support to the parents at these difficult moments,” he added, saying he was going to the scene to meet with the families.
“Laval is wholeheartedly with you and will be there for you.”
