I'm just struggling to see what the big hubbub is for the expansion. We know Billy Bishop cannot/will not be expanded to handle large single-aisles or widebodies. I can't think of another city the size of Toronto (or bigger) building or expanding an airport so close to downtown, just to hopefully get 10 million passenger traffic per year. All on small, single-aisle jets.
Is this critically needed? Compared to say, more local rail transit, Alto, Pearson expansion, 400 series highway expansion.
I am worried about how traffic will be at Lakeshore and Bathurst. Setting aside the more frequent noise and West Portland height restrictions, which I am told are outweighed by the benefits. How will car traffic be mitigated? Are the 509 & 511 up to the task?
I can't help but think that Billy Bishop is being expanded because it already exists, therefore it's easy, with less attention to things like road traffic. If it did not exist, then more resources and attention would be going to Pearson.
