London Heritage Alteration Review - City Bylaw Process

In London, Ontario, owners in a designated heritage district must follow an alteration review process before changing features that affect heritage character. This guide explains how the municipal review works, who enforces the rules, typical steps to apply for a heritage alteration review, and common outcomes for approvals or refusals. It summarizes official City and provincial authority sources and provides practical action steps to prepare an application, make a complaint, or appeal a decision. For the controlling municipal procedures and application requirements see the City of London Heritage Alteration Permit information page^[1].

Overview of the Alteration Review Process

The alteration review applies where a property lies within a municipal Heritage Conservation District or is individually designated under the Ontario Heritage Act. The municipal heritage planner and Heritage Conservation Advisory Committee (where applicable) will typically review proposed changes, and Council may have final approval depending on the designation and the nature of the work. Consult the City of London Heritage Conservation Districts guidance for district-specific policies and design guidelines here^[2].

Typical Steps in Review

• Prepare a complete application with drawings, photos and a description of proposed changes.
• Submit materials to the City heritage planner or Planning Services as directed on the municipal application page.
• Heritage staff and any advisory committee review for consistency with the district plan or designation bylaw.
• Decision by delegated authority or City Council; conditions may be imposed or applicant may be asked to revise plans.
• Where required, a Heritage Alteration Permit or other municipal permit is issued before work may start.
