Key facts

  • Maude Théroux-Séguin is the Borough Mayor of Ahuntsic-Cartierville, one of Montréal's boroughs — chairing the borough council and sitting on Conseil municipal de Montréal. Théroux-Séguin is not Montréal's city-wide Mayor; for issues affecting the whole city, write to the Mayor instead.
  • Municipal councils handle local matters: property tax, zoning and building permits, garbage/recycling/water, snow removal, local bylaws (noise, parking, pets), and parks and recreation. For health care, tenant disputes, or ODSP/OSAP, write to your provincial representative instead; for immigration, federal taxes, or passports, write to your MP.
  • Identify yourself as a resident: full name, home address, and which ward or the general city if the seat is city-wide, so staff can confirm you're within Montréal. Constituent mail is prioritized.
  • Letters to municipal councillors need regular postage — there's no postage-free rule at the municipal level (unlike mail to federal MPs).
  • PostPal prints your letter and deposits it with Canada Post the next business day for $6 — no printer, envelope, or stamps needed.

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 Théroux-Séguin at Conseil municipal de Montréal

    Théroux-Séguin chairs the Ahuntsic-Cartierville borough council and can raise a borough-specific issue directly with staff or at a council meeting. Mail goes to Conseil municipal de Montréal's office at 555, rue Chabanel Ouest, 6e étage, bureau 600, Montréal, QC H2N 2H8.

  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 Théroux-Séguin'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

    Send it without printing anything

    Write your letter in PostPal with Maude Théroux-Séguin's address prefilled — we print it, stamp it, and hand it to Canada Post the next business day for $6.

Common questions

What is Maude Théroux-Séguin's mailing address?

Maude Théroux-Séguin, Borough Mayor, 555, rue Chabanel Ouest, 6e étage, bureau 600, Montréal QC H2N 2H8.

Is Théroux-Séguin the mayor of Montréal?

No — Théroux-Séguin is the Borough Mayor of Ahuntsic-Cartierville, one of Montréal's boroughs, and chairs that borough's council. Montréal also has one city-wide Mayor, elected separately, who chairs the central city council that Théroux-Séguin also sits on. Write to Théroux-Séguin for anything specific to Ahuntsic-Cartierville; write to the city-wide Mayor for issues affecting all of Montréal.

Should I write to my borough mayor, 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 Théroux-Séguin?

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 Ahuntsic-Cartierville to write to Théroux-Séguin?

No, but ward-specific casework is normally only taken up for residents of Ahuntsic-Cartierville. If you live elsewhere in Montréal, your own ward councillor is the better first contact — or write to Théroux-Séguin specifically about a citywide issue.

Will Maude Théroux-Séguin 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.
