Two Canadians were among the 66 passengers and crew on an EgyptAir jet that disappeared from radar early Thursday en route from Paris to Cairo, according to a statement from Foreign Affairs Minister Stéphane Dion.
Egypt has not ruled out the possibility it could have been a terrorist attack.
EgyptAir says a Canadian named Marwa Hamdy was on the flight.
Apparently, Hamdy was from Saskatoon and moved to Cairo about 10 years ago after marrying an Egyptian.
A friend of Hamdy told Postmedia on Thursday Hamdy was born and raised in Saskatoon but currently lived in Cairo, where she was working.
Hamdy was returning from a trip to see family in Paris, Haleh Banani said in an interview with Postmedia.
Banani said Hamdy was a mother of three boys aged 11 to 16.
