How to send your letter

  1. 1

    Check it’s a municipal matter

    Montréal council can act on local files: property tax, zoning and permits, garbage/recycling/water service, snow removal, local bylaws, and parks. If your issue is health care, a tenancy dispute, or ODSP/OSAP, that's provincial — write to your MPP/MLA instead; immigration, EI, or passports go to your federal MP.

  2. 2

    Write to Demers-Dubé at Conseil municipal de Montréal

    Demers-Dubé represents Vieux-Rosemont (Rosemont–La Petite-Patrie) and can raise a ward-specific issue directly with staff or at a council meeting. Mail goes to Conseil municipal de Montréal's office at 5650, rue D'Iberville, Montréal, QC H2G 2B3.

  3. 3

    Say who you are and where you live

    Open with your full name, address, and which ward you're in (if the seat is ward-based) so Demers-Dubé's office can confirm you're a resident. One page, one issue, and a specific ask — support or oppose an item on an upcoming agenda, or raise a problem with a department.

  4. 4

Common questions

What is Olivier Demers-Dubé's mailing address?

Olivier Demers-Dubé, Councillor, 5650, rue D'Iberville, Montréal QC H2G 2B3.

Should I write to my councillor, my MPP, or my MP?

Depends on the issue. City council is municipal: property tax, zoning, garbage/water, snow removal, local bylaws, parks. Your MPP/MLA is provincial: health care, education, housing and tenant disputes, ODSP/OSAP. Your MP is federal: immigration, taxes, EI, passports. Name the program — the wrong office will redirect you, but starting in the right place is faster.

Do I need a stamp to write to Demers-Dubé?

Yes — mail to municipal councillors takes regular postage; there's no postage-free rule at the municipal level. If you'd rather skip the stamp and printer entirely, PostPal prints and mails your letter for $6 flat.

Do I have to live in Vieux-Rosemont (Rosemont–La Petite-Patrie) to write to Demers-Dubé?

No, but ward-specific casework is normally only taken up for residents of Vieux-Rosemont (Rosemont–La Petite-Patrie). If you live elsewhere in Montréal, your own ward councillor is the better first contact — or write to Demers-Dubé specifically about a citywide issue.

Will Olivier Demers-Dubé actually read my letter?

Constituent mail is logged by council office staff, and issues tied to an upcoming agenda item get flagged directly. Include your return address — PostPal prints yours automatically — so a reply has somewhere to go.
