We've been at this for about 16 months. Sixteen months before that, we weren't too informed about how the process works. We've learned a lot on how things go.
What we understand is that the Greater Toronto Airports Authority is responsible for operations on the ground, parking the planes and moving them around. Once they get to a runway, they become the responsibility of Nav Canada. Nav Canada controls the runways and the airspace.
They are two private companies. They used to have connections to the government, but now they operate completely independently. Then you have Transport Canada, which we called, the last time we talked to them, the police in this process. They enforce the rules. You also have the Transportation Safety Board of Canada, which does the investigations.
That's the way it's structured here in Canada. It has worked quite well for many years.
In terms of the challenge, this is industry experts coming to us. We don't go and ask for the questions; it's amazing how many people come to us. They say the funding challenges are there. Transport Canada has difficulties doing what they've done in the past, and we have incredible growth. The GTAA talked about a 2% growth of their passenger volume on an annual basis. They're somewhere between 7% and 9%. Business is really good.
