2026 Property Taxes
The Township’s 2026 budget shows how tax-rate changes affect residential properties and distinguishes waterfront, non-waterfront, farm and condominium assessments. Final property taxes include Township, County of Lambton and education components.
Zoning & Development
Confirm zoning before relying on residential, agricultural, commercial or industrial development potential. Riverfront and rural sites can also involve setbacks, conservation review, servicing and environmental considerations.
Building Permits & Additional Units
Building, plumbing and septic permits may be required for new construction, additions, renovations, accessory structures and additional dwelling units. Provincial housing permissions do not remove local zoning, Building Code, servicing or hazard requirements.
