Key facts

  • Write the inmate's full name on the first line and "c/o Établissement de détention de Sept-Îles" below it — mail without a usable inmate name is returned or destroyed.
  • All incoming mail is opened and inspected for contraband; personal (non-privileged) mail can be read.
  • Do not enclose cash, gift cards, postage stamps, jewellery, or anything besides paper — prohibited enclosures are seized.
  • Inmates are transferred between facilities without notice. Confirm the person is still at Établissement de détention de Sept-Îles before mailing, and double-check the address against Quebec Correctional Services (Services correctionnels du Québec)'s official listing.
  • Include your full return address so the person can write back — some facilities refuse mail without one.
  • PostPal prints and deposits your letter with Canada Post the next business day, so you can write from anywhere without a printer or stamps.

How to send your letter

  1. 1

    Confirm the person is still at Établissement de détention de Sept-Îles

    Inmates move between facilities without notice — after sentencing, for security reclassification, or for programs. Confirm during a call or visit that they are still at Établissement de détention de Sept-Îles before you send anything, and double-check the mailing address against the official Quebec listing (linked in the sources below).

  2. 2

    Address it to the inmate, care of the facility

    First line: the inmate's full name (the name they are held under, not a nickname). Second line: c/o Établissement de détention de Sept-Îles. Then the mailing address: 65, boulevard Vigneault, Sept-Îles QC G4R 4L2.

  3. 3

    Keep the contents to paper only

    A letter on plain paper is always safest. No cash, stamps, gift cards, stickers, glitter, perfume, or laminated items — facilities seize prohibited enclosures and may reject the whole letter. If you want to send photos or documents, call the facility first to confirm what it accepts.

  4. 4

    Send it without a trip to the post office

    Write or upload your letter to PostPal with the address above prefilled, and we print, envelope, and deposit it with Canada Post the next business day for $6 — with your return address printed so they can write back.

Common questions

How do I address a letter to an inmate at Établissement de détention de Sept-Îles?

Put the inmate's full name on the first line, "c/o Établissement de détention de Sept-Îles" on the second line, then the facility's mailing address: 65, boulevard Vigneault, Sept-Îles QC G4R 4L2. Include your own return address so they can write back.

Is mail to Établissement de détention de Sept-Îles opened and read?

Expect it to be. Correctional facilities inspect incoming mail for contraband, and non-privileged personal mail can be read under Quebec Correctional Services (Services correctionnels du Québec)'s rules. Never include cash, gift cards, stamps, or anything besides paper — unauthorized enclosures are confiscated and can get the letter rejected.

What happens if the person has been transferred or released?

The letter will not be forwarded to you or reliably to them. Inmates are moved between facilities without notice, so confirm the person is still at Établissement de détention de Sept-Îles — ideally during a phone call or visit — before mailing anything important.

Can the inmate write back to me?

Yes. Include a complete return address on your letter. Inmates in Quebec provincial custody can send outgoing personal mail, though they may need to cover their own postage.

Can I send photos or printed documents?

Plain paper letters and standard photo prints are generally accepted; polaroids, hard objects, and anything glued, taped, or perfumed usually are not. Rules vary by facility and change — call Établissement de détention de Sept-Îles to confirm before sending anything other than a plain letter.
