No, it wouldn't. And Mark's argument here is based on the idea that aviation can run more efficiently with a less congested airport. However, a 10% savings in fuel burn, for example, doesn't
Nav Canada does control and manage airspace. But the number of slots and the approaches at all the airports in the GTA determine the traffic flows around the GTA. This is what I was referring to by my comment on separating commercial and GA traffic.
For example, Buttonville being relatively close to Pearson (by air), really put a damper on both airports' operations.
There is a deep relationship between the all powerful GTAA bean counters and NavCanada, a true love hate relationship. The GTAA wants to stuff as many aircraft as possible into the airport, which Nav Canada loves due to the revenue they get for each one , but at the same time actually doing it safely without breaking the laws of physics or man rests on ATC ( Nav Canada) and the pilots they must heard.. Both are increasingly nervous about the “ insane” new masterplan numbers from the GTAA which are setting new goals of 48 movements an hour on runway 23 and 60 combined on runway the 24 L&R set. More over these numbers are for 18 hours a day in all weather conditions. This is not for an hour or two, but 18 hours a day, this has never been achieved in North America at any other airport, even ones without Canadas weather problems.
While setting lofty goals is fine, they need to be achievable, all of the time for the slot system to work. Otherwise they simply overflow into Pearson “after hours” time slots and Pearson will become the fragile link in North America’s airport system.
Surprisingly Buttonville, which is 20 nm away, but is right under Pearson runway 23 approach, has no impact on Pearsons traffic flow now that they have dropped it’s airspace to 2000ft. This was done to allow simultaneous operations with both horizontal and vertical separation on 24L and 23 . Buttonville will be open for another 5 years, possibly much longer now that displaced exec jet traffic from Pearson has rediscovered it.
The boys at transport Canada are not happy campers right now. This is what they are worrying about:

As always The pilots will be the adults in the room, will try thier best to make it work by waviering wake separation on departure as they are able.
We all need to be worried by the profit motive driving both the GTAA and NavCanada at this point. The GTAA is turning into an accidental realestate empire, and NavCanada is bleeding cash looking for ways to cut costs and boost revenue.
