Sir, I think that's a point where we have suburbs, for instance, in which there's a house per acre. I live in one like that, Chelsea, and we have a train that goes by. Frankly, no one is very bothered by it. It's two locomotives a night with passenger cars. It could really tick people off, but it goes by at a moderate speed and it brings economic benefits to the region. People appreciate that.
The same appreciation might not be found in, say, Etobicoke or Mississauga, where it's very densely populated and people might react very differently to this assemblage.
That's one aspect. The other is to go towards these things progressively, rather than setting a draconian goal for now.
