Overview

The City of Markham's Natural Heritage Constraints Map Terms of Reference, June 2025, listed on the Guidelines and Terms of Reference page. A constraints map identifies the limits of development in relation to the natural environment, usually within an Environmental Impact Study or alone where the EIS is waived. The terms explain when one may accompany an application within or next to the Greenway System, who prepares it, and what the map shows: base map, development and natural heritage information such as areas of natural and scientific interest.
