Overview
A two-page brochure in the City of Markham's Heritage Matters series, first issued April 2008 and revised June 2025, reprinting the Ontario Ministry of Citizenship and Multiculturalism's eight guiding principles for conserving built heritage properties, which Markham applies in its heritage conservation work. Each principle carries a short rule and its reason: respect for documentary evidence, original location, historic material, original fabric and the building's history, reversibility, legibility and maintenance, with an example of numbering and storing stones when a new door opening is cut.
