Thank you very much for your question.
Again, I will respond in English, just because it's better for everyone.
The first thing to realize is that invoking article 5 is a decision that NATO states will make. If there were an attack on, let's say, a Canadian commercial satellite like RADARSAT-2, one of the first decisions that the Canadian government would have to make is whether it would treat this as an armed attack that would trigger the NATO obligation.
My guess is that in the situation involving a single satellite, we would not invoke article 5. It would be an attack on an important piece of Canadian infrastructure, but it would not be an attack within Canadian territory. We would be conscious that invoking article 5 would signal that we were into a direct conflict with a nuclear-armed state, which would be seem to be highly undesirable. It's a self-judging invocation. That's the first thing to say.
The consequences, however, could be very serious. RADARSAT-2 is the principal source of revenue for Canada's largest space company. I don't know whether its bottom line could handle losing such an important revenue-generating piece of equipment. Then there are all of the users who make use of RADARSAT-2—everything from oil companies using the imagery to monitor pipelines, looking for slumping of ground and looking for erosion problems around their equipment and their operations in remote areas, to the Canadian Coast Guard icebreakers navigating the Northwest Passage, trying to avoid multi-year ice. The list goes on and on.
Yes, it would be a very serious thing in terms of being just as important as a piece of critical infrastructure located on the ground here in Canada.
