The addresses we hold

The address a cancellation letter to Canadian Securities Administrators needs, and every other address we hold, starting in Montréal: copy the lines exactly and the envelope sorts itself.

Where the letter goesMailing address

Canadian Securities AdministratorsRue du Square-Victoria 8002010H3C 0B4 MontréalCanada

The Canada address on file for Canadian Securities Administrators. Postal code H3C 0B4.

How to address the envelope

  1. Copy the address exactly

    Address the envelope to Rue du Square-Victoria 800, 2010, H3C 0B4 Montréal, Canada. Everything on those lines matters for the sorting machines, so nothing is abbreviated by hand.

  2. Put your own address on it

    Top-left, your own name and address. A return address is what the post office needs to send the letter back if Canadian Securities Administrators has moved.

  3. Ask for certified mail

    Certified, not courier: buy it at the counter, keep the postmarked slip, and the letter to Montréal is traceable from the article number until it is signed for.

  4. Keep the proof together

    Your copy of the letter, the mailing receipt and the tracking record belong together in one file.
