Incorporating in Construction in Quebec (2026): The Guide by Trade
In construction, the order of the steps is dictated by regulation: the corporation must exist before the licence application, because RBQ, CMEQ and CMMTQ licences are not transferable from an individual to a corporation. Incorp-Québec prepares your corporation for $497 all-in, including the $397 government fee.
This guide covers the sector's common core. For the rules specific to your licence, go directly to the Choose your trade section: general contractor and renovation, electrician (CMEQ), plumber and heating (CMMTQ). On the road instead? See our guide to the incorporated truck driver.
Why incorporation comes first in construction
Starting a construction business in Quebec is not "get your licence, then set up your company." It's the other way around, and this isn't an opinion: in the official process of the Régie du bâtiment du Québec (Quebec Building Authority), choosing your legal structure and registering with the Registraire des entreprises come before filing the licence application.
The reason is simple: the licence is issued to a business identified by its NEQ, and it is not transferable. If you qualify first as a sole proprietor and then incorporate, the RBQ treats the change of NEQ as a change of legal status and requires a new, complete application — "even if you already hold one." The result: application fees paid twice, a surety bond to redo in the corporation's name, and the full processing time to go through again. The only consolation: competencies already demonstrated by the qualified officer remain recognized — no new exams if the same officer is qualifying for the same subcategories.
Incorporating first avoids this detour. To understand the structure itself (shares, directors, limited liability), see our comparison of legal structures in Quebec and our guide When should you incorporate in Quebec?.
The sector's common regulatory core
Whatever your trade, an incorporated construction business in Quebec faces the same major obligations. Each trade guide details them for its specific licence; here is the overview.
The licence: RBQ or delegated corporation, depending on the trade
Carrying out regulated construction work without a licence is an offence under the Building Act, punishable by significant fines. The licence is issued by the RBQ for most trades (general contractor, renovation, excavation, roofing…), but by a delegated corporation for two of them: the CMEQ for electricians and the CMMTQ for plumbers and heating contractors. In every case, the same logic applies: the licence belongs to the business that holds it, and a new entity must file its own application.
The qualified officer
To obtain its licence, the corporation must have at least one officer who qualifies as a qualified officer (répondant). The RBQ evaluates their competencies in four areas: administration, site safety management, project and site management, execution of work. Three routes: exams ($105.27 each in 2026), recognized training, or a professional record demonstrating experience.
The licence surety bond
The corporation must provide a surety bond of $20,000 (specialized subcategories) or $40,000 (as soon as a general subcategory is involved), issued in its name by a surety company, certain insurance companies, or contractor associations. Worth watching: a draft regulation published in February 2026 proposes raising these amounts to $30,000 and $60,000 — this is not in force, and no date has been announced.
Registration with the CCQ
As soon as the business carries out work subject to the R-20 Act, it must register with the Commission de la construction du Québec (Quebec Construction Commission) (a $350 fee) — and registration requires the licence number, which again fixes the order of the steps. A point often overlooked: a corporation's director can be an employee of their own company (impossible for a sole proprietorship), with a competency certificate for regulated work; self-employed contractor status, meanwhile, remains reserved for specialized licences and minor work.
The CNESST
Registration is mandatory within 60 days of the first worker's first day of work (possible 30 days beforehand) with the CNESST. The average 2026 premium rate is $1.54 per $100 of payroll, but the actual rate depends on the classification unit — construction sits well above the average. The corporation's officer is not automatically covered: personal protection coverage is optional.
The Revenu Québec compliance certificate (ARQ)
Required for public contracts of $25,000 or more and, for private construction subcontracting, as soon as contracts with the same contractor reach $25,000 before taxes cumulatively within the calendar year — once that threshold is crossed, every subsequent contract between the two parties is covered. The contractor hiring you must verify the authenticity of your certificate.
The legal hypothec of construction
Contractors and subcontractors benefit from a legal hypothec on the added value brought to the building — a right that is identical whether you are incorporated or not. What changes once incorporated: contracts must be in the corporation's name, which becomes the creditor. The deadlines are strict: a notice registered within 30 days of the end of the work, and legal action within 6 months.
The start-up sequence, in order
| Step | Organization | Key point (2026) |
|---|---|---|
| 1. Incorporate the corporation | Registraire des entreprises | $397 in government fees — $497 all-in with Incorp-Québec; NEQ obtained, then $106 in annual rights |
| 2. Apply for the licence in the corporation's name | RBQ (or CMEQ/CMMTQ) | Qualified officer + surety bond + $1,291.69 (general) or $849.41 (specialized); official processing time of 60 days, excluding queues |
| 3. Register with the CCQ | CCQ | $350; requires the licence number; work subject to R-20 |
| 4. Register with the CNESST | CNESST | Within 60 days of the first worker (possible 30 days beforehand) |
| 5. GST/QST and source deductions | Revenu Québec | GST/QST mandatory beyond $30,000 in taxable supplies; deductions as of the first salary, including your own |
| 6. ARQ as needed | Revenu Québec | Public contracts ≥ $25,000; subcontracting ≥ $25,000/calendar year with the same client |
The golden rule: the corporation cannot sign any regulated construction contract before holding its own licence. Plan the processing time into your schedule. Between steps 1 and 2, take the opportunity to open the business bank account; the details of the incorporation process itself are in our steps to set up a corporation, and the full costs are in our incorporation costs guide. To estimate the taxes on your future invoices, use our GST/QST calculator.
Step 1, handled for $497 all-in
Your Quebec corporation — articles of incorporation, initial declaration, $397 government fees included — ready for the licence application. A form of about 20 minutes, filed directly with the Registraire des entreprises.
Choose your trade
The common core above applies to everyone; the finer rules — licence subcategories, the competent corporation, exams, tax particulars — vary by trade. Each guide walks through the full process for its licence.
| Trade | Licence | Dedicated guide |
|---|---|---|
| General contractor and renovation | RBQ (general subcategories, including 1.2 small buildings and 1.3 all-purpose) | Incorporating as a construction contractor |
| Electrician | CMEQ, an RBQ delegated corporation | Incorporating as an electrician in Quebec |
| Plumber and heating | CMMTQ, an RBQ delegated corporation | Incorporating as a plumber in Quebec |
More trade guides will be added (excavation, roofing, masonry…). In the meantime, this page's common core and the general contractor guide cover the essential steps for specialized RBQ licences.
CAE codes for the construction sector (40xx, 42xx, 44xx)
When incorporating the corporation, the Registrar asks for an economic activity code (CAE). The construction sector occupies three main groups: builders and developers (40xx), specialized contractors (42xx) and construction-related services (44xx). Our CAE code search tool covers all sectors; here are the ones for construction.

FAQ — Incorporating in construction in Quebec
Should I incorporate before or after applying for my licence?
Before. In the RBQ's official process, choosing your legal structure and registering with the Registraire des entreprises come before the licence application: the licence is issued to a business identified by its NEQ. Qualifying first as a sole proprietor and then incorporating requires filing an entirely new application, with new fees and a new processing time.
Is my current licence transferable to my new corporation?
No. For the RBQ, moving from a sole proprietorship to a corporation is a change of legal status — a change of NEQ — which requires a new licence application, "even if you already hold one": new fees, a new surety bond in the corporation's name, and the full processing time again.
Does my qualified officer have to retake their exams after incorporating?
No. The RBQ recognizes competencies already demonstrated: if the same qualified officer is qualifying for the same subcategories, they do not have to retake the exams. The new licence application in the corporation's name is still mandatory, however.
Can a single qualified officer cover several subcategories?
The RBQ evaluates the qualified officer in four qualification areas (administration, safety, project and site management, execution of work). A single officer can qualify for all the subcategories requested if they demonstrate the required competencies, and the business can also designate several qualified officers ($105.27 per additional officer added in 2026).
Is CCQ registration mandatory if I work alone?
As soon as your work is subject to the R-20 Act, yes — registration (a $350 fee) actually requires your licence number. Self-employed contractor status is reserved for specialized subcategory licences and limited to maintenance, repair and minor renovation; a general contractor operates as an employer.
What licence surety bond do I need to provide?
$20,000 for one or more specialized subcategories, $40,000 as soon as a general subcategory is involved. The bond is issued in the corporation's name by a surety company, certain insurance companies, or contractor associations. A draft regulation published in February 2026 proposes raising these amounts to $30,000 and $60,000, but it is not in force.
When must I register my corporation with the CNESST?
Within 60 days of your first worker's first day of work; registration is possible up to 30 days beforehand. Note: a corporation's officer is not automatically covered — they can apply for personal protection coverage, which is optional.
What is the Revenu Québec compliance certificate and when is it required?
A document issued by Revenu Québec confirming that the business is in good standing. It is required for public contracts of $25,000 or more and, for private construction subcontracting, as soon as contracts with the same contractor reach $25,000 before taxes cumulatively within the calendar year — with every subsequent contract between the two parties then being covered.
