Airport operations are very complex, and making changes to our operations takes time. Our friends at TANG, as well as Councillor Knoll, mentioned that changes are slowly happening. I think that is a reflection of the complexity of the issue.
You asked a question about a series of different studies. There was one study, a Nav Canada independent airspace review, that was undertaken by Helios. That was released in September 2017. Nav Canada responded with an action plan about how they would enact the recommendations of that report. They are doing that on an ongoing basis and do updates about that at each of our CENAC public meetings. That does happen regularly.
As part of our own practice, we also commissioned Helios to do a noise management best practices benchmarking study for us, which we undertook, and which forms the cornerstone of the noise management action plan we are currently pursuing. We are very much taking the recommendations that came out of that study and exploring how to implement them. It's also important to know that we also conducted consultations around what it would look like and what our guiding principles need to be for consideration. We did that through a randomly selected residents' reference panel, which TANG also mentioned, but we also did that through a series of workshops throughout the summer of 2017 to gather that feedback and guidance.
Finally, you asked about the report from David Inch. His recommendations, as part of the report that went to Nav Canada, fundamentally form the six ideas that Hillary referenced in her remarks. Those six ideas are currently being implemented. It is frustrating that things are happening at a slow pace, but good projects are going forward.
