What’s here. Toronto sites with a City file submitted since 2021 and still open (rezonings, subdivisions, site plans and condominiums, read from the City’s open data), plus a few files checked by hand. A site plan with no rezoning behind it is here only when it’s for homes. Other cities aren’t in yet.
