Emergency services are at the scene of a train derailment Thursday morning on Montreal's south shore, where they are urging citizens to stay away from the area.

Eight cars of a Canadian National train derailed today (Thursday, Nov. 14) in suburban Montreal, releasing a cloud of a potentially hazardous material and leading to a shelter-in-place order for nearby residents as well as area schools.

People in a part of Longueuil, Que., were being asked to stay indoors with their doors and windows closed on Thursday morning after a train derailed, spilling an unknown quantity of hydrogen peroxide.

Longueuil police say it doesn’t initially appear anyone was hurt, but fire officials are dealing with a hydrogen peroxide spill
