Provincial zoning regulation for former Halton County lands to be converted into municipal by-laws

COUNTY OF HALTON (NOW PART OF THE REGIONAL MUNICIPALITIES OF HALTON AND PEEL), TOWN OF OAKVILLE (NOW PART OF THE TOWNS OF HALTON HILLS, MILTON, OAKVILLE AND THE CITY OF MISSISSAUGA) — under the Ontario Planning and Development Act, 1994

Plain-language summary · AI-assisted · not legal advice

A provincial regulation that has governed land use and zoning for parts of what are now the Towns of Oakville, Milton, and Halton Hills, and the City of Mississauga will be wound down. The bulk of the regulation's provisions and schedules are being revoked, but rather than simply disappearing, the relevant sections are being re-cast as deemed zoning by-laws of each respective municipality. This means the same zoning rules will continue to apply locally, but as municipal by-laws rather than provincial regulation. Landowners, developers, and planners working on properties in these municipalities covered by the old provincial regulation should confirm how their specific parcels are addressed in the new deemed by-law framework for their municipality. No substantive land use rules appear to be changing — only the legal form and authority under which they operate.

Who this affects: landowners in Oakville, Milton, Halton Hills, and Mississauga covered by the regulation · land developers and builders · municipal planners and planning departments · real estate lawyers and conveyancers
