Displaying your licence

Contractors and owner-builders, according to the Building Act, you are required to display your licence number issued by the Régie du bâtiment du Québec (RBQ) on several mediums. However, it is strictly prohibited to display the flag of the Government of Québec as well as the RBQ logo. The RBQ’s inspectors and investigators enforce this rule as part of their surveillance duties.

The RBQ logo

It is strictly prohibited to use, on any material or item whatsoever, either the flag emblem identifying the Government of Québec or the RBQ logo.

Where and how to display your licence number?

An RBQ licence number has 10 digits. It must be indicated as follows: "RBQ licence: XXXX-XXXX-XX".

You must indicate your RBQ licence number on all of the following.

Signs on construction sites

You must indicate your licence number on the signs you put up on construction sites if your company name is indicated there.

Websites and Social networks

If you advertise your services on your website, professional or personal social networks, you must indicate your licence number.


Vehicles that display the company’s business name, that travel on public streets or on construction sites must display the RBQ licence number. This applies to light-duty trucks, heavy trucks and heavy machinery. For tractor semi-trailers, the licence number must be displayed on either the tractor or the trailer, or both, depending on whether advertising appears on one or both vehicle components. A single indication of the RBQ licence number is sufficient for each vehicle or vehicle part.


You must indicate your licence number on any type of advertising, including your business cards. In the phonebook, whenever a listing mentions your services (e.g. renovation or construction) or your activity sector (e.g. residential or commercial), your RBQ licence number must be indicated. However, simple listings (e.g. ABC Construction Inc., address, telephone number: 418-555-0000) do not need to include your licence number.  

Estimates, bids, contracts, account statements and invoices

You must indicate your RBQ licence number on your estimates, bids, contracts, account statements and invoices.

Promotional items: no licence number required

Promotional items (pens, cups, key rings, etc.) that display the company's name are not subject to this rule.

Exemptions for some contractors from displaying their licence

Contractors who are members of the Corporation des maîtres électriciens du Québec or the Corporation des maîtres mécaniciens en tuyauterie du Québec are not required to display their RBQ licence number because they are identified by the logos of their respective professional corporations. Contractors domiciled outside Québec are also exempt from this rule.
