The Borough of Saint-Laurent provides several tools and databanks to orientate its residential and corporate citizens intent on making changes to their properties and to provide answers to questions regarding bylaws, construction or cleanliness.


Assistant-permis (or Permit wizard) is a research and information tool that provides personalized information for specific addresses. Residents will find answers to their questions by consulting fact sheets and fillable forms for all permits and authorization certificates relating to the following topics: accessory building, accessory equipment, antenna, basement dwellings, interior or exterior modifications, new construction or addition, parking spaces, plumbing connection, pool and spa, signage, tree and landscaping.

Info-zonage (or Info-zoning) is a research and dissemination tool for Saint-Laurent’s grids of uses and standards.

Info-zonage data can be helpful for individuals and professionals: urban developers, architects, land surveyors, notaries, etc. Simply enter a street address or lot number to obtain the corresponding grid of uses and standards.
