The City of Richmond Hill Policy Planning Division's terms of reference for a Cultural Heritage Impact Assessment, last updated January 2026. It explains what a CHIA is, who prepares one (members of the Canadian Association of Heritage Professionals or a similar body) and why, citing section 4.6 of the Provincial Policy Statement 2024. It then sets out two outlines, one for heritage designated properties, with evaluation under Ontario Regulation 9/06, and one for properties adjacent to them, followed by submission instructions and resources.
