When Montréal Projects Need an Environmental Impact Review
When an Environmental Impact Review Is Required
In Montréal, Quebec, some development and infrastructure projects trigger an environmental impact review before permits or approvals are granted. Typical triggers include large-scale land-use changes, projects affecting protected natural areas, waterfront or shoreline works, major tree removal, or construction on known contaminated or flood-prone sites. Municipal planning authorities may also require studies as part of zoning or site plan approvals. For municipal guidance on environmental priorities and project triggers, consult the City of Montréal environment pages and permit guidance Montreal Environment[1] and the City permit and urban planning portal Permits & Planning[2]. Large projects may also fall under Quebec's provincial environmental assessment procedures Quebec environmental assessment[3].

Specific monetary fines for missing or incomplete environmental reviews are not specified on the cited municipal pages; see the linked official sources for details about enforcement practices and orders.[1][2][3]

A specific municipal "environmental impact" form is not published on the cited City pages; developers are generally asked to submit technical reports, environmental studies or permit applications through the City planning portal or as part of a permit package.[2] Provincial project assessments follow Quebec procedures and related forms, where applicable.[3]

How decisions are made
Decisions on whether a review is required are usually made by municipal planners or an environmental review committee during the permit or planning application intake. Factors include project size, location, potential impacts, and existing municipal policies. For projects that may trigger provincial review, the Ministère de l'Environnement's criteria apply; consult the provincial guidance for thresholds and submission requirements.[3]
