How to send your letter

  1. 1

    Pick the right office for your issue

    Writing about a bill, a vote, or a national policy? Use the House of Commons address — it's postage-free and reaches Eric Duncan's parliamentary staff.

  2. 2

    Say who you are and where you live

    Open with your full name, address, and postal code. MPs' offices sort mail by whether the writer is a constituent, and your postal code is how they confirm you live in Stormont—Dundas—Glengarry. If you're writing to an MP other than your own, say why their role or riding matters to your issue.

  3. 3

    Keep it to one issue with a clear ask

    One page, one topic, one specific request — support or oppose a bill, raise a question in the House, meet with you, or take up your casework file. A short letter with a concrete ask gets a real reply; a multi-issue essay gets a form letter.
