Complaint about the contracting process

A company or group of companies may file a complaint with the CNESST about the contracting process under the Act respecting contracting by public bodies (ACPB) and the Act respecting the Autorité des marchés publics (AMP)

We make a complaints procedure available to our clients in order to collect comments, examine and respond to complaints and make the necessary recommendations.  


A complaint about the contracting process is filed in order to denounce a decision or a condition that does not comply with the normative framework in the event of a public call for tenders or a contract by mutual agreement (ACPB, s. 13, par. 1(4)). 

The provisions concerning complaints also apply to the process for the certification of goods or the qualification of suppliers, service providers or entrepreneurs.

Who may file a complaint?

An company or group of companies interested in participating in the awarding process or their representative may file a complaint under section 21.0.4 of the ACPB.

Definition of a company

“For the purposes of this Act, ‘enterprise’ means a legal person established for a private interest, a general, limited or undeclared partnership or a natural person who operates a sole proprietorship.” (s. 13.1, par. 2 of the ACPB). Before filing a complaint, it is suggested that you contact the public body to obtain all the information about the call for tenders (s. 13.1, par. 1(2) of the ACPB).

Why file a complaint?

Complaints are filed in order to denounce a situation of non-compliance.

Deadline for filing a complaint

During the period for filing complaints indicated in the call for tenders document or in the notice of intention and in the online call for tenders system (SEAO – Système électronique d’appel d’offres).
