Mr. Chair, as with other measures—different sorts of sanctions we've put in place—the impact of this will be both in its symbolism and its substance.
In its symbolism, I think there is no more clear expression to Russia of its isolation on the world stage than the fact that its aircraft are physically unable to travel over a wide range of countries. This is, in particular, a shocking development for those close to Putin, those enriched under his regime. For those who have used these flights to maintain an international lifestyle, this will bite.
The other aspect that will be important is that it has an economic bite on Russia. As Russia is unable to fly its aircraft, as it imposes—as it has with the U.K., for example—reciprocal measures which don't permit overflights of Russia, this will be a loss of significant revenue to Russia from those overflights.
The fact that Canada and other countries have put in place this ban certainly is a clear message to Russia that its actions are unacceptable and that it is becoming a pariah. On the other hand, it will bite directly into the economy in terms of their ability to generate revenue from their aircraft.
