Land Use and Zoning Ontario 4 Minutes Read · published February 12, 2026 Flag of Ontario

In London, Ontario mixed-use zoning allows a combination of residential, commercial and institutional uses on the same property or within the same building, subject to the City of London zoning by-law and Official Plan policies. This article explains how mixed-use designations are applied in London, how to confirm permitted uses in a specific zone, what planning approvals or amendments may be required, and how enforcement and appeals work when uses conflict with the by-law.

What mixed-use zoning means in London

Mixed-use designations generally permit ground-floor commercial or service uses with residential units above, and may include offices, personal services and limited institutional uses where the zone text allows it. Check the City of London consolidated Zoning By-law Z.-1 for the precise list of permitted uses that apply to a parcel or zone type; permitted uses vary by zone and site-specific zoning exceptions City of London Zoning By-law Z.-1[1].

Not all mixed-use labels allow the same activities; always check the specific zone text.

How to confirm permitted uses on a property

  • Search the property by municipal address or roll number through the City mapping and zoning search or contact Planning staff.
  • Consult the zone provisions and definitions in Zoning By-law Z.-1 for use classifications and any site-specific exceptions Zoning By-law Z.-1[1].
  • Determine whether the proposed use is listed as permitted, accessory, or requires a zoning by-law amendment or special permission such as a site plan control application.

Development approvals and common steps

  • Submit planning applications and fees using the City of London forms and fee schedules Planning forms & fees[2].
