Zoning by-laws are a set of regulations under the Planning Act. Zoning by-laws address matters like how land and buildings are used, building heights and size, density, paring, lot sizes, driveways, landscaping, and more.
For questions about how to find out what the zoning is for a property, try the "What's My Zoning?" guide.
Council has adopted an Interim Control By-law
that limits the ability to expand, rebuild, or add to many residential properties while a study on changes to the zoning by-law is undertaken. For more details, see this page
