Irrespective of what this proposal might called, I'd like to see that it is NOT built.
Its yet another sprawl inducing, pollution promoting monstrosity blighting the landscape.
I don't think highways are evil, but I think it is self evident that they do promote sprawl and their construction, primarily through greenfield areas, should be done selectively, carefully, sparingly as a last resort, where intensification is clearly insufficient to meet growth/demand and where other solutions that are less polluting or sprawl promoting are not feasible and/or have already been implemented.
If it is a MUST to serve this corridor with new infrastructure, I want a freight rail line first, then passenger/commuter service if demand warrants, second.
Only once that is exhausted should a new highway even be considered.
An ROW big enough for a highway could be protected for, but used for the rail corridor FIRST, then have a highway added later if absolutely necessary.
The building of new highways has never resulted in less traffic or better planning, I don't see this changing now. I would like to see what little countryside we have left in the GTA preserved.
