A police operation was being conducted at the Magdeleine school, in La Prairie, because of the bomb threat. All students were evacuated and police established a large security perimeter.
Earlier, Louis-Philippe-Paré high school in Châteauguay, Montérégie, was closed for the day. Students and staff received death threats Thursday night.
The Grandes-Seigneuries School Service Center contacted the Chateauguay Police Department.
The latter recommended closing the Louis-Philippe-Paré school for that day.
The school principal, Stéphane Brault, contacted the parents of about 2,200 students at the establishment.
Friday noon, there were no reports of any arrests.
Last Monday, threats were sent to the same school, but in the evening, police arrested a 22-year-old man, Alexandre Charbonneau, who was detained while pending his release investigation.
Châteauguay police have not established a link between this suspect and the events on Friday.
