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 Charles Sousa's parliamentary staff. Need help with a federal file (immigration, passport, CRA, EI, pensions)? The constituency office in Mississauga handles casework for Mississauga—Lakeshore residents.

  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 Mississauga—Lakeshore. 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.

  4. 4

    Send it without printing anything

    Write your letter in PostPal with Charles Sousa's address prefilled and we print, envelope, and deposit it with Canada Post the next business day for $6. (If you'd rather mail it yourself, remember: no stamp needed to the Ottawa address, but regular postage to the Mississauga office.)
