Porter wants to fly more planes
no they don't. they are not proposing to increase the daily limit for ALL airlines (including Air Canada) of 202 daily movements. (take offs and landings)
Porter wants to fly bigger planes
Well, ya. this isn't an inherently bad thing though. as others have stated, it can create efficiencies. Instead of 16 daily flights to Montreal or whatever it is now, it may be 10.
which use more fuel more often
as Keithz mentioned, its the same amount of fuel per passenger.
What? no. Porter hasn't determined the flightpaths yet, but they will likely be an improvement over the current ones. The jets can have steeper landing and take off angles, meaning the planes get out of the way much faster.
Its no different than it is now, and is done in an attempt to reduce noise. The height the planes are at when above the park are higher than any birds would be anyway.
densest residential and commercial districts
.. and? the lakeshore area closest to the airport despite the highrises isn't really that dense, there is too much park space and other things that restrict buildable space. the core of the city is a couple km away, much further away than the major airport employment zone south of Pearson. I guess we should be screaming bloody murder about pearson too, considering a couple hundred thousand people work within 2km of it as well.
and expect most passengers - more passengers - to get there by car.
nope, only 20% drive, and the proposal includes increased frequency of the Union station shuttle as well as an underground streetcar loop.
The increase in cancer risk alone makes this proposal completely inappropriate. The status quo is a reasonable compromise, says anyone who has studied the impacts of the expansion in detail.
half the negatives you listed aren't even changing in the proposal.. (increased flights, flightpath, etc.)
