Key facts

  • Mat Siscoe is the Mayor on St. Catharines City Council.
  • 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 St. Catharines. 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).
  • Prefer email? [email protected] reaches the same office — but a physical letter is harder to overlook, especially ahead of a council vote.
  • 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

    St. Catharines 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 Siscoe at St. Catharines City Council

    As mayor, Siscoe sets the council agenda and can direct a request to the right department. Mail goes to St. Catharines City Council's office at 50 Church Street, P.O. Box 3012, St. Catharines, ON L2R 7C2.

  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 Siscoe'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 Mat Siscoe's address prefilled — we print it, stamp it, and hand it to Canada Post the next business day for $6.

Common questions

What is Mat Siscoe's mailing address?

Mat Siscoe, Mayor, 50 Church Street, P.O. Box 3012, St. Catharines ON L2R 7C2.

Should I write to my 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 Siscoe?

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 St. Catharines to write to Siscoe?

Generally yes for casework — write to Siscoe as a resident or business owner in St. Catharines. If you live in a neighbouring municipality, your own city council is the right recipient.

Will Mat Siscoe 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.
