In terms of looking at the airspace change, we're guided by the airspace change communications and consultation protocol. It has some robust requirements and accountabilities for Nav Canada when it's conducting airspace change.
That includes how and when consultations are conducted and how we communicate the impacts of those changes. It also provides some timeline guidance in terms of how soon you have to give notification of a public consultation event. There are also follow-up reporting requirements. A public engagement report has to be produced following a consultation and before a recommendation to implement the changes is made. That's a key facet.
There's another piece to it where we need to follow up. It's called the 180-day review, where we come back approximately six months after implementation and look at operational performance, as well as any community feedback we received as a result of the change.
