The school board announced that both Jean-de-Brebeuf and Cardinal Roy high schools shut their classrooms, and support services are being offered. Four of the victims, all from Quebec, were members of one family, and the other two were acquaintances.
Up to 32 people were killed when al-Qaida linked terrorists stormed a hotel and cafe in the West African country's capital of Ouagadougou late Friday.
Friends and the school board identified the Canadian victims as Yves Carrier, his wife Gladys Chamberland, their adult son Charlelie Carrier and Yves' adult daughter Maude Carrier.
The school board said Maude Carrier and Chabot were both secondary school teachers. Yves Carrier was an assistant principal before his retirement, and Bernier had been an administrator at two elementary schools before she retired.
Gladys Chamberland worked for Quebec's natural resources ministry.
