What on earth are you…

What on earth are you thinking? Ontario has an incredible amount of land, but a comparatively small amount of it is designated as protected land. While the residents of the GTA have my sympathy for the conditions they've crammed themselves into, there are other places to live! You've given barely any information on this. Have you done land studies? The property you've proposed to add to it, is that the same type of land that you've decided to remove? Will that keep the ecosystem around the same as it is currently?
That's not even getting STARTED on the fact that the Greenbelt is a time-honored sanctuary for our wildlife- some of which is endangered! If we start messing with the boundaries of the Greenbelt then where will you stop? What effect would this have on migration routes?
