Markham Environmental Impact Review Requirements
Markham, Ontario requires environmental impact reviews for many major development proposals to protect natural heritage, wetlands, watercourses and other sensitive features. This guide explains when a review is likely required, who enforces the rules, what applications or studies are typically requested, typical compliance steps, and how to start a submission to the City of Markham planning process. It is written for developers, consultants, landowners and community groups preparing or responding to applications in Markham.
Overview of the Review Process
Environmental impact reviews (often called Environmental Impact Studies or EIS) assess potential effects of a proposed development on natural features and functions. The City integrates these reviews into the development application and permits workflow to determine appropriate mitigation, conditions of approval, or refusals. Major projects commonly require pre-application consultation, a scoped EIS prepared by a qualified professional, and coordination with conservation authorities and City planning staff.
