Ottawa is citing demonstrations across Egypt and what it calls an "unpredictable security situation."
Egyptian President Mohamed Morsi has declared a 30-day state of emergency and night curfew in three provinces hit hardest by the wave of violence that has left more than 50 dead since Friday.
Riots are being attributed mainly to politicized Egyptian soccer fans, known as Ultras, who have been battling with police.
Those same soccer fans helped fuel protests against the military leadership that ruled Egypt between the fall of former strongman president Hosni Mubarak and the election last June of Morsi — the country's first freely elected leader.
