It's a very good question. Thank you for it.
The history of RADARSAT-2 is linked to the exceptional character of the technology, the fact that it was so cutting edge. Having this three-metre resolution and its ability to see at night through clouds was something that concerned the United States in terms of having this imagery available on the commercial market, available for anyone to buy. So a prolonged struggle occurred that involved, initially, NASA refusing to actually launch the satellite for MDA, and also ITAR issues that were thrown in the way.
Monsieur Garneau would know more about this history than I do, but the point here is that in order to actually get the satellite up and to satisfy our American allies, we did make concessions, and some of them are perhaps more significant than is publicly known, because there's actually a confidential annex to the treaty that Mr. Axworthy and Madame Albright signed.
The point here is that we still have priority access to this satellite. If we have reason to think there's a Liberian-flagged single-hulled oil tanker coming towards the Northwest Passage, we can get imagery of it right away and we can continue to track that vessel.
