Key facts

  • Peggy Sattler is the NDP MPP for London West in the Legislative Assembly of Ontario.
  • MPPs handle provincial matters: health care, education, housing and tenant issues, ODSP, OSAP, driver's licences, and provincial permits. For immigration, taxes, EI, or passports, write to your federal MP instead.
  • The constituency office in London is where casework happens — write there for help with a provincial file.
  • Identify yourself as a constituent: full name, home address, and postal code, so staff can confirm you live in London West. Constituent mail is prioritized.
  • Letters to MPPs need regular postage — the postage-free rule only covers federal MPs in Ottawa.
  • Prefer email? [email protected] reaches the same office — but a physical letter is harder to overlook.
  • 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 provincial matter

    MPPs can act on provincial files: health care, schools, housing and the Landlord and Tenant Board, ODSP/OSAP, ServiceOntario problems. If your issue is immigration, federal taxes, EI, or passports, your federal MP is the right recipient — not Peggy Sattler.

  2. 2

    Pick the right office

    Opinions on bills and provincial policy go to Queen’s Park. Personal casework goes to the constituency office in London — that's where the caseworkers who can chase a file sit.

  3. 3

    Say who you are and where you live

    Open with your full name, address, and postal code so Sattler's staff can confirm you live in London West. One page, one issue, and a specific ask — support a bill, raise your case with a ministry, or meet with you.

  4. 4

    Send it without printing anything

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

Common questions

What is Peggy Sattler's mailing address?

At the legislature: Peggy Sattler, MPP, Room 368, Main Legislative Building, Queen's Park, Toronto ON M7A 1A5. For constituency matters: Peggy Sattler, MPP, Unit 101, 240 Commissioners Rd. W, London ON N6J 1Y1.

Should I write to my MPP or my MP?

Depends on the issue. MPPs are provincial: health care, education, housing and tenant disputes, ODSP, OSAP, driver's licences. MPs are federal: immigration, taxes, EI, CPP, passports. If you're not sure, name the program — the office will redirect you, but starting in the right place is faster.

Do I need a stamp to write to Sattler?

Yes — letters to provincial legislators take regular postage (the postage-free rule only applies to federal MPs in Ottawa). 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 London West to write to Sattler?

No, but constituency casework is normally only taken up for residents of London West. If you live elsewhere in Ontario, find your own MPP — or write to Sattler specifically about an issue they've championed.

Will Peggy Sattler actually read and reply to my letter?

Constituency mail is logged and answered by Sattler's staff, and recurring issues get flagged to the member directly. Include your return address — PostPal prints yours automatically — so the reply has somewhere to go.
