Key facts

  • Letters to any MP at the House of Commons, Ottawa ON K1A 0A6 are postage-free when mailed from within Canada — the same rule covers the Prime Minister and the Speaker.
  • Constituency offices are for casework: passport delays, immigration files, EI, CPP, and CRA disputes. Regular postage applies to those addresses — they're in each MP's page in our directory.
  • Identify yourself as a constituent: your full name, address, and postal code. Offices prioritize mail from voters who live in the riding, and the postal code is how they check.
  • One letter, one issue, one clear ask (vote a certain way, raise a question, take a meeting, open a casework file). Personal letters carry more weight than petitions and form emails.
  • You can write to any MP, not just your own — ministers about their portfolios, committee members about their studies — but say why you're writing to them specifically.
  • PostPal prints your letter and deposits it with Canada Post the next business day for $6 — no printer, envelope, or stamps needed, with your return address printed for the reply.

How to send your letter

  1. 1

    Find your MP

    Enter your postal code on ourcommons.ca/members ("Find your Member of Parliament") — or browse our MP directory, which lists every MP with their Ottawa and constituency addresses ready to prefill into a letter.

  2. 2

    Pick the office that matches your issue

    Legislation, votes, and national policy → the House of Commons address (postage-free). Personal help with a federal department — immigration, passports, CRA, EI, pensions → the constituency office in your riding, which is where caseworkers sit.

  3. 3

    Write a letter that gets a real reply

    State that you are a constituent, with your postal code. One page. One issue. End with a specific, answerable request. Be firm but civil — staff route abusive mail straight to the bin, and persuadable MPs read respectful disagreement.

  4. 4

    Mail it — with or without a stamp

    Mailing it yourself? The Ottawa address needs no postage from within Canada. No printer or envelopes? Write it in PostPal and we print and deposit it with Canada Post the next business day for $6, return address included.

Common questions

Is it really free to mail a letter to an MP?

Yes. Under the Canada Post Corporation Act, mail addressed to any sitting MP at the House of Commons, Ottawa ON K1A 0A6 travels free of postage when sent from within Canada. Constituency offices are not covered — regular postage applies there.

How do I find out who my MP is?

Search your postal code on ourcommons.ca/members — the official House of Commons directory. Each MP also has a page in our MP directory with their mailing addresses formatted and ready to send.

Should I write to my MP or to the minister responsible?

Both is often right. Your own MP is obliged to represent you and can escalate on your behalf; the minister owns the file. If you write to a minister who isn't your MP, copy your own MP — their office can follow up in a way you can't.

Does a mailed letter matter more than an email?

Offices log both, but physical mail is scarcer, harder to bulk-delete, and widely treated as a stronger signal of effort — a stack of letters on one issue gets noticed. The postage-free rule exists precisely so cost never stops a constituent from writing.

Can I write to the Prime Minister this way?

Yes — the Prime Minister is an MP, so the same postage-free House of Commons address works. Keep the same rules: one issue, a clear ask, and your name and address for the reply.
