Process for obtaining a permit or certificate

The need for a permit or certificate

There are a number of objectives underlying the obligation to obtain a permit or certificate: the safety of occupants and buildings, the protection of heritage, wetlands and shorelines as well as the harmony and architectural integration of the various living environments. Proof of your project’s compliance, before it is carried out, protects you from the civil and penal consequences that could result from failure to meet the requirements of the bylaws.

Assistance from the Direction de l’aménagement urbain et des services aux entreprises (DAUSE)

To check whether standards are applicable to your project and whether a permit or certificate is required, in order to ensure that the bylaws are properly understood. At every step of the process, the borough can assist you in obtaining a permit or certificate.

Preparation of the required documents

In some cases and depending on the applicable legislation, plans signed and sealed by a professional (e.g. architect or engineer) may be required.

How to submit the application

Submit your application online or at the permit counter and pay the (non-refundable) application fees to examine your file. Please note that additional fees may be required during processing, in addition to other permit or certificate applications (e.g. tree cutting). Two (2) copies of all required documents must be enclosed. Any missing documents will cause additional delays in processing your application.

Examination of your file

Your file will be examined according to the current legislation (zoning, construction, RMM, PIIAD, PPCMOI, demolition, subdivision, connection, etc.). A review in relation to the National Building Code may also be conducted if the project so requires, in compliance with construction and safety standards. If the application is subject to a discretionary tool (PIIAD, PPCMOI, demolition), an examination by professional urban planning consultants will be carried out. In such cases, a recommendation from the Comité consultatif d’urbanisme (CCU), the urban planning advisory committee, will be required and a resolution will have to be adopted at a meeting of LaSalle’s Borough Council to approve the project. These types of permits or certificates involve an additional delay of at least two (2) months.

Issuance of the permit or certificate

Once the examination of your application has been completed and all requirements have been met, the permit or certificate is issued.

Start of work

Your work, including demolition, can begin only once the permit is issued and must be completed within the specified time frame. Your permit must be posted at the work site. If you wish to extend your permit, please do so before the permit expires and please note that additional fees will apply.

Inspection of work

An inspector may inspect the work at any time to ensure compliance. If the work is not in compliance, a notice of infraction will be issued and a statement of offence (with a fine) may be issued if the necessary corrections are not made within the required time.
