Your four questions are heavily weighted in favour of developers capitalizing on the perceived need for missing middle housing and "gentle density" housing. Although I am not at all opposed to sustainable development, we need to make better use of our existing housing stock rather than incurring the environmental costs of tearing existing structures down and replacing them with track housing or "gentle density" housing in heritage area. "Gentle density" works in Toronto or Mississauga, but it will destroy the small-town feel of heritage districts in Fergus and Elora (in Centre Wellington Township, where I live) and other small town in Ontario. Municipalities should have the right to meet the social contract that exists between them and their citizens, not have one-size-fits-all "solutions" imposed upon them by Queen's Park.
