Key facts

  • Write the inmate's full name on the first line and "c/o North Slave Correctional Complex" 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 North Slave Correctional Complex before mailing, and double-check the address against the Northwest Territories' Corrections Service'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 North Slave Correctional Complex

    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 North Slave Correctional Complex before you send anything, and double-check the mailing address against the official Northwest Territories 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 North Slave Correctional Complex. Then the mailing address: PO Box 278, 71 Kam Lake Rd, Yellowknife NT X1A 2N2.

  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 North Slave Correctional Complex?

Put the inmate's full name on the first line, "c/o North Slave Correctional Complex" on the second line, then the facility's mailing address: PO Box 278, 71 Kam Lake Rd, Yellowknife NT X1A 2N2. Include your own return address so they can write back.

Is mail to North Slave Correctional Complex opened and read?

Expect it to be. Correctional facilities inspect incoming mail for contraband, and non-privileged personal mail can be read under the Northwest Territories' Corrections Service'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 North Slave Correctional Complex — 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 Northwest Territories's 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 North Slave Correctional Complex to confirm before sending anything other than a plain letter.
