This government needs to…

This government needs to make the Greenbelt bigger, not develop it. In the current climate emergency, every acre of watershed, wetland, and forest is needed to limit environmental instability.

Housing development should focus on existing spaces, and building structurally dense apartments and public housing (build vertically, not horizontally).

I have attached the Ontario Government's own Housing Affordability Task Force report regarding housing development.

From Page 10 of the report:
While less analysis has been done in other Ontario communities, it’s estimated that about half of all residential land in Ottawa is zoned for single-detached housing, meaning nothing else may be built on a lot without public consultation and an amendment to the zoning by-law. In some suburbs around Toronto, single unit zoning dominates residential land use, even close to GO Transit stations and major highways. One result is that more growth is pushing past urban boundaries and turning farmland into housing. Undeveloped land inside and outside existing municipal boundaries must
be part of the solution, particularly in northern and rural communities, but isn’t nearly enough on its own. Most of the solution must come from densification. Greenbelts and other
environmentally sensitive areas must be protected, and farms provide food and food security. Relying too heavily on undeveloped land would whittle away too much of the
already small share of land devoted to agriculture.

Allowing more gentle density also makes better use of roads, water and wastewater systems, transit and other public services that are already in place and have capacity, instead of having to be built in new areas.

From a perspective of Public Good, both in a local and global perspective, developing the Greenbelt is both too expensive, and too damaging to the environment, for the dubious benefit of opening undeveloped land for housing that could be easily built in currently developed areas.
