How to file a complaint?

We deal with complaints regarding administrative entities of the City of Montréal only.

We are a service of last resort, which means that:

• you must first file a complaint with the City of Montréal; and
• the management team of the administrative entity in question must have had the opportunity to address your complaint.

You have one year from the date of the events at the source of the complaint to request our intervention, unless you can demonstrate exceptional circumstances.
 
Visit the “Can we investigate your complaint?” page to learn more.

To review your complaint, we will need certain information, including:

• your contact information or the contact information of the person on whose behalf you are filing the complaint.
• the name of the City of Montréal’s administrative unit that is the subject of your complaint.
• the date you contacted the City of Montréal’s to file your initial complaint (if you noted it).
• a description of the situation that led to your complaint.
• a description of the resolution you are seeking.
• copies of supporting documents (photos, e-mails, etc.) and documents exchanged with the City of Montréal.
