Overview

A two-page brochure in the City of Markham's Heritage Matters…in Markham series, June 2025, introducing the City's four heritage conservation districts under Part V of the Ontario Heritage Act: Thornhill, Markham Village, Buttonville and Unionville. It explains what a district is and its purpose, the kind of new construction considered appropriate, where to find each district's Heritage District Plan, the approvals that apply to exterior alterations, new construction and demolition, financial assistance, property values and district signage and streetscape features.

What it covers

  • What is the purpose of the district?
  • What type of new construction is appropriate?
  • Where can I learn more about district requirements and how to alter my property?
  • How do I get a copy of a Heritage District Plan?
  • What types of approvals are required?
  • What financial assistance is available?
  • Does designation affect property values?
  • What special features are found in heritage conservation districts?
Check this against the municipality before you rely on it.
