In addition to being a member in good standing of a professional corporation, designers must comply with the
Building Act 
with respect to the conception of drawings and specifications.
The Act makes provision for the adoption of a
Construction Code
and a
Safety Code
governing buildings and facilities intended for public use, and electrical installations, pressure installations, petroleum equipment installations, plumbing installations, and installations intended to use, store or distribute gas.
Obligations to master the requirements
Section 18 of the Building Act confirms the obligation of designers to comply with the Construction Code on penalty of fines or penal proceedings.
The two codes are adopted chapter by chapter and are gradually replacing other statutes and the 30-odd regulations that applied previously. The purpose of this approach is obviously to simplify regulation but also to better define the responsibilities of construction professionals and owners.
In your capacity as a designer, you must obtain the tools necessary to properly interpret the Construction Code, in particular through training.
Drawings and specifications
Designers, architects, engineers, technologists and other professionals involved in construction or the installation of equipment must comply with the standards in the Construction Code governing the conception of drawings and specifications.
Such drawings and specifications must be available on the worksite at the request of RBQ inspectors.
