Mediation is a course of action that allows both you and your contractor, by mutual agreement, to submit your dispute to a mediator with the goal of reaching an agreement.

Submit a mediation request

A mediation request must be submitted within 30 days following receipt of the plan manager’s decision, and must indicate the name of the mediator chosen by the two parties. Consult the list of authorized mediators [Fr]This link leaves Guarantee Plan for New Residential Buildings Website. per region.

The mediation request must be addressed to:

  • by email, at
  • by mail, to:

    Direction des plans de garantie
    Régie du bâtiment du Québec
    255, boulevard Crémazie Est, 2e étage
    Montréal (Québec) H2M 1L5

Upon receipt of this request, the ministre des Affaires municipales et de l’Habitation will designate a mediator and share this information with the guarantor.

All mediation sessions are confidential; nothing that is said during them can be used as evidence in other files unless you agree otherwise.


The cost of mediation is shared equally between you, the contractor, and the plan manager, if they participate. You can also agree amongst yourselves on another way of splitting the cost.

If it doesn't work: arbitration

If mediation fails, and it is not possible to reach an agreement with the plan manager, you can take recourse by going to arbitration. You will have 30 days, following receipt by registered mail of the mediator's notice of the total or partial failure of the mediation process, to consult an arbitration body authorized.


Yes, you can go directly to arbitration without turning to mediation beforehand.
