You know, on the one hand, I like the idea of the fixed link to YTZ. Here's why:
1) The economic potential of a quick hop over to NYC on a Dash-8, completely avoiding Pearson, is big. Same goes for ORD, BOS, YOW, YUL, and others.
2) This could in effect save taxpayers money. If business expands, then prices will go down. Because the only people who fly YOW-YTZ are politicians, we, the taxpayer, will save money from fewer "travel costs".
3) If, as somebody pointed out, the airport accounts for 3% of the noise around there, what's a few more Dash-8s? I'd bet that the real noise makers are some of the private airplanes anyways...
4) It'll be nice to see SOME development down in that area beyond condos. The lack of other development will eventually hurt the condo market down there, and this'll get things to pick up.
Now here are my concerns:
1) What about that rail link from Union to Pearson? Regardless of YTZ's expansion, I'm still going to want a better way to get out there when I fly somewhere further than Ottawa or New York. I'd hate to see this plan go by the wayside in favour of the Island airport - in truth, I think it's more important.
2) Although I do like the idea of economic development in the area, I am scared that it'll be the wrong kind of development. I know Robert Fung's waterfront development plan is a tad unrealistic, I still want that area to be aesthetically pleasing - as a Torontonian, not a hippie. I'm less concerned with the Island itself than the state of the waterfront. That area at eh foot of the DVP is gross, and while any improvement is nice, I'd prefer a park, or some other kind of use, instead of MORE condos. (As an aside, did you know that Toronto is the condo capital of the world? We build more condos than any other city - 14,000 in 2001, twice as many as Chicago..)
3) As much as people joke about 732s @ YTZ, I'd hate to see it happen. Ever wandered around downtown Boston, and heard the jets roaring by? As an airliner fan, I love the novelty, but I'd hate to have to live through it...
Just my two cents...
