Law R-20, what types of work are affected?

In Quebec, the construction industry is governed by specific regulations designed to protect workers, ensure the quality of work, and regulate labor relations. One of the most important laws in this area is Bill R-20, officially known as the Act Respecting Labour Relations, Vocational Training, and Workforce Management in the Construction Industry.
For any house, cottage, or garage project, understanding this law is essential. At Plan Maison Québec, we believe that a well-planned project always begins with a clear understanding of the legal framework.
A key law for all residential construction
Introduced in 1968, Act R-20 applies to virtually all work considered "construction" in the province. Its main objective is to ensure that workers in the sector benefit from fair and safe working conditions, while standardizing the required professional skills and qualifications. This law mandates the Commission de la construction du Québec (CCQ) to oversee its enforcement.
Whether you're planning to build a new lakeside cottage, expand your family home, or completely renovate an existing garage, you're likely affected by this legislation.

What types of work are covered?
According to Act R-20, "construction work" is not limited to large-scale projects. It includes any activity related to the foundation, erection, renovation, repair, modification, maintenance, or demolition of a building or structure. This covers everything from the installation of mechanical and electrical systems to finishing work such as the installation of partitions.
Thus, digging a foundation, installing load-bearing walls, replacing a plumbing system, or even redoing a roof are activities regulated by Act R-20. Even certain projects considered "lighter," such as basement development or attic insulation, may fall within this scope if they require structural or technical interventions.
Exceptions: Can you do certain jobs yourself?
There are, however, some important exceptions to be aware of, particularly for owner-occupants. Indeed, an owner can carry out certain construction work on their own residence without necessarily being subject to the rules of Act R-20. However, this work must be carried out:
on a dwelling occupied as their principal residence,
without the assistance of paid workers,
and not for profit.

In other words, if you are a homeowner who wants to renovate your kitchen or redo the bathroom in your own cottage, without hiring employees or a contractor, you may be exempt from certain obligations. However, significant restrictions apply. For example, work on electrical or gas systems requires specific qualifications and licenses, regardless of the homeowner's status.
You should also be careful not to confuse volunteer assistance with disguised paid work. Even if friends or family members help you for free, the CCQ can investigate if it suspects the work is being carried out improperly.
Community or voluntary work: a gray area
Another special case concerns volunteer work. This is permitted in certain contexts, for example, in community or humanitarian projects. However, there is a fine line between volunteering and illegal work. For work to be considered truly voluntary, it must be performed without any form of remuneration or exchange, without pressure or obligation, and must not be carried out in a professional or commercial context.
In the case of a personal project, such as building a garage on your land, the involvement of volunteers can quickly become problematic if one of them owns a construction company or if there is an implicit quid pro quo.

The crucial role of the CCQ
The Commission de la construction du Québec is the organization responsible for implementing Act R-20. It issues competency cards to workers, ensures construction site compliance, and can issue fines for non-compliance with regulations.
If a project is deemed non-compliant—for example, if an unauthorized contractor is carrying out work or if workers without competency cards are present on a construction site—the CCQ can suspend work, impose financial penalties, or even initiate legal action.
The penalties can be severe, both for contractors and clients. This is why it is essential to plan your project in advance, with the help of competent and informed professionals.

Nevertheless, it requires increased rigor and preparation, especially for individuals wishing to undertake major renovations.
