I think the point Chester is trying to make, is that all those vacant areas are spoken for, either for future residential use which achieves the maximal use of the land in a growing community, or industrial use, which is also desired close to the city, particularly for cement, power, etc.. I suppose Rogers could buy the land, but that assumes a lot regarding planning approvals, incl OPA, ZBLA. It also assumes a willing seller, and a price that makes sense for Rogers. It also assumes assemblage of lands is possible to create enough space.
I frankly don't see it, unless it's out by like Hearn or Unwin or something, and then you need transit for sure.
