This actually aligns with my view. I think a new GA airport (perhaps with freight capabilities) makes a lot of sense. I'm just concerned that all the talk from the GTAA and the federal government is talk of a second major airport.
It's PR fluff in my opinion. There just isn't the business case for it. What airlines would want to move there? In reality it'll be an oversized GA airport at start.
We might end up with a small terminal catering to charter flights and short-hops to Ottawa and Montreal. But the latter requires no more infrastructure than what's there at YTZ and even that's a big if. The catchment area of the Pickering airport is 40% farmland. As long as YTZ is around, I would argue that between YYZ running A321s with 180 pax and YTZ running 110 seat CS100s, there is still plenty of capacity in the region to grow short-haul capacity. So I think it'll be a very long time before we see scheduled commercial flights at Pickering. It'll happen at YHM (Hamilton) before it happens at Pickering. Actually, I'm honestly surprised that Hamilton doesn't have more commercial passenger traffic (though they have lots of cargo).
The amount of money that has been spent in
London and New York on trying to plan for a single, centralized airport (and that Berlin has spent on building one) should be a lesson to us that a second airport should only be considered once expansion at Pearson is completely maxed out.
It's very interesting to watch the debate in London. You won't find too many people arguing that air traffic should be capped (like you see over here). There is a broad consensus, that London's status as a global city is very much reliant on London being a strong aviation hub for the world. The consensus is broad enough that you have crazy plans like Boris Island which was rumoured to cost 23 billion pounds when fully built out.
Here in Toronto, Air Canada has some ambitions of becoming the next KLM, which a strong focus on connecting Europe to the US, Central and South America. Their fleet buys are positioning them in that direction and once the 787s come in, they'll be launching a whole bunch of new services from Toronto to Africa, India, China, Korea, Japan, and South America:

It's an amibtion that is supported by the feds largely because of the economic implications of such a strategy for Toronto. Add to this to the fact that so many foreign carriers now have Toronto on their radar. It could just be that, the feds are hoping to make some room in anticipation of all this international traffic growth at YYZ.
