Key facts

  • Todd J. McCarthy is the Progressive Conservative MPP for Durham 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.
  • Todd J. McCarthy also serves in cabinet at the Ministry of Environment, Conservation and Parks — portfolio mail goes to the ministry address above.
  • The constituency office in Bowmanville is where casework happens — write there for help with a provincial file.

  • 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.

How to send your letter

    Check it’s a provincial matter

    Pick the right office

    Opinions on bills and provincial policy go to the Ministry of Environment, Conservation and Parks address. Personal casework goes to the constituency office in Bowmanville — that's where the caseworkers who can chase a file sit.

Common questions

What is Todd J. McCarthy's mailing address?

At the legislature: Todd J. McCarthy, MPP, Ministry of Environment, Conservation and Parks, 5th Floor, 777 Bay St., Toronto ON M7A 2J3. For constituency matters: Todd J. McCarthy, MPP, 23 King St. W, Bowmanville ON L1C 1R2.

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.

Can I write to Todd J. McCarthy as minister?

Yes — Todd J. McCarthy heads the Ministry of Environment, Conservation and Parks, and mail about that portfolio goes to the ministry address above. Keep riding-specific casework separate: send it to the constituency office, where it's handled whether or not the member is in cabinet.

Do I need a stamp to write to McCarthy?

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 Durham to write to McCarthy?

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

Will Todd J. McCarthy actually read and reply to my letter?

Constituency mail is logged and answered by McCarthy'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.
