Filing a monthly report and paying amounts due

Employers must submit their monthly report electronically through the CCQ’s online services, or via an accounting software or an authorized payroll service provider.

Several guidance tools are available to support employers with completion, uploading, and amendment of the monthly report. 

Through the online services 

Employers may fill out their monthly report directly and completely securely in their file, 24 hours a day, 7 days a week, free of charge. This service is offered under protected and secure conditions.

By using a service provider

Payroll services are service providers that can directly transmit the employer’s monthly report. The payroll service simply has to be in the list of suppliers authorized by the CCQ. 

View the list of authorized service providers (accounting software and payroll services).

By uploading a file in JSON format

Various accounting software packages allow for automated creation of an electronic file containing all the data needed to file monthly reports. The person responsible can file a monthly report by uploading a file in JSON format by clicking on Rapport mensuel in the Mon organisation dropdown menu in their online file.  

The monthly report must be filed and the total due must be paid by the 15th day of the month following the period covered. Payment methods available are:

• Payment by preauthorized debit: to use this payment method, simply fill out the registration form.
• Electronic payment: the employer may pay through it's financial institution by using the payee CCQ - Rapport mensuel (the name may differ in different financial institutions) .

Demande de retrait ou de réduction des heures déclarées au rapport mensuel

If an error in the monthly report is noticed after it has been filed, the employer must submit an amended monthly report via the online services. View the video Modifying a monthly report.

Withdrawal or reduction of hours

When the revision concerns a withdrawal or reduction of hours declared, the employer must attach the form Demande de retrait ou de réduction des heures déclarées au rapport mensuel to its amended monthly report by clicking on the paperclip icon on the relevant line in the “Employee details” section. The form must be signed by the employee concerned in the request in order to authorize the CCQ to withdraw or reduce the hours in his or her file.

It is important to provide the amounts corresponding to the correction of hours requested so that the salary, the vacations and the paid statutory holidays, and union dues are also corrected.

Addition of hours 

If the request for revision involves an addition to the hours declared in the monthly report, the employer must calculate the remittances and contributions corresponding to the modification requested. The amount must then be paid by electronic payment, separate from any payment for the monthly report in the current period, through the employer’s financial institution only, by choosing the payee CCQ - Rapport mensuel. 

Please note that payments related to a revision of the monthly report cannot be made by preauthorized debit.

When an employer submits a monthly report containing erroneous information, this information becomes noncompliant data. 
The employer will receive a notification by email in order to correct or delete the erroneous information.

The calculations of contributions may differ by from a few cents to a few dollars between those performed by employers and those performed by the Commission de la construction du Québec (CCQ). Some amounts entered by the employer are based on weekly payroll calculations, whereas the CCQ’s calculations are done on a monthly basis. The differences may be higher or lower.

The amount calculated by the CCQ takes precedence, and the employer must pay the amount invoiced by the CCQ. In this case, no amendments are necessary.

Discrepancies in previous monthly reports

Discrepancies may be found in previously submitted monthly reports because the CCQ has converted these monthly reports from the old computer systems to the new ones. This is explained by the fact that previously, the contributions were calculated on the total amount of the monthly report whereas in the new systems the contribution is calculated only for each employee.

The note Conversion may be found at the top of the monthly report, if this is the case. No action is required by the employer and there is no impact on the contributions paid. 

The amount invoiced by the CCQ is the amount that includes all validations and discrepancies. You must pay the amount invoiced. On the other hand, it is not useful to amend a monthly report to adjust for rounding discrepancies. A process for reimbursing credit balances is in place based on certain thresholds.

If you have no applicable hours for the period for a regular employee, you must not include that worker in the monthly report.

The M, F, and L statuses no longer exist. Reassess the role and indicate status A, C, or regular depending on the case.
In practical terms:

• Hours declared under statuses M (production machinery) and L (preparation hours) may become status A (voluntary contribution with social benefits).

• Status F (paid administrator) becomes regular status (regular employee).

If you would like more details concerning all statuses, see the complete table here.

These hours must be recorded by employers and their employees.

Status F (Paid administrator – with social benefits) was removed from the monthly reports with the pay period beginning December 28, 2025 (monthly report of January 2026) and replaced by regular status. The Commission de la construction du Québec (CCQ) will not collect union dues from company officers who are registered as such with the CCQ.

Company officers must maintain a union allegiance in their file. For the submission of monthly reports as of January 2026, if you have not yet joined a union, here is the form to fill out. An official signature is required; copies are not accepted. 

Who is a company officer?
It is person filling one of the following roles in your organization and registered as such with the CCQ: president, administrator, secretary, vice-president, shareholder, partner, or treasurer.

Before the hours for a designated representative are declared, it is essential that the person be officially registered as designated representative in the company’s file. 

This verification may be made in the online services, from the “Mon organisation” menu, by clicking on “Autorisations et relations” and then on “Contacts de l’organisation.”

If the person is not registered or if a change must be made, fill out the registration form and send the document via “Contactez nous,” under the category “Nous joindre” in the Catalogue de services in your online file.

Certain specific situations may require a different status but in general the appropriate status is status E.

Examples:

• DESR who works alone, without an employee = status E with social benefits
• DESR who works with an employee = status E, with or without social benefits
• DESR who does maintenance, repairs, or renovations, operates heavy machinery, or does excavation/landscaping for an organization or for another person without an employee = status C as self-employed contractor

The DESR may choose to contribute to social benefits or not.

The new version of the monthly report platform now performs many calculations automatically.

However, when you use status E:

The amounts in the boxes for taxable wages and vacations/holidays must be entered manually.

These amounts can be based on the pay stub.

 

Changes

If it is necessary to make an adjustment, the amounts can be changed up to the 15th day of the following submission period, like all amendments, without interest or penalty.
