The Safer Skies initiative was born out of the unspeakable tragedy that happened to flight PS752, which was shot down by the Iranian military. Canada is now a world leader in enhancing civil aviation security. We've been working, along with our partners at the International Civil Aviation Organization, ICAO, and others.
We have put in place measures to report potential risks and threats to civil aviation. To directly answer the question, at the beginning of and prior to the start of the invasion, given the intelligence and the information we had, we actually imposed a NOTAM over the territory of Ukraine to ensure that civil aviation operators were aware of the risk of flying over there.
