Cancellation Adt: Easy Method

What is Adt

ADT is a provider of monitored security systems and related services, offering residential and DIY/self‑setup monitoring plans, equipment packages, and ongoing alarm monitoring. In Canada, ADT‑branded services are often provided in partnership with Telus for certain plans; terms can include fixed contract lengths, monthly monitoring fees, and potential deposits or equipment arrangements.

How to cancel Adt

  • ADT cancellations cannot be completed online. For standard residential contracts follow the instructions in your order confirmation email or call ADT at (888) 392‑2039. For DIY/self‑setup contracts you must call ADT at 1‑800‑238‑2727 (1‑800‑ADT‑ASAP) at least 30 days before the end of the current monthly term to cancel. When you call, state you want to cancel, ask for the department handling cancellations, and request a cancellation confirmation number or written confirmation.

What happens when you cancel

When your ADT monitoring is cancelled, ADT will stop providing alarm monitoring and associated services after the effective cancellation date. If you are on a recurring monthly term, service access typically ends at the end of the paid term unless an effective date is agreed. Cancellation can affect any bundled services, app access, and any monitoring‑linked features (for example remote video or alarm response). ADT’s systems may continue to bill if the cancellation was not properly processed or documented, so obtaining written confirmation and checking subsequent statements is important.

Will I get a refund?

ADT’s published terms state that there is no refund for any prepaid service term if you cancel early. If you paid a security deposit, ADT’s terms say the deposit is refundable within 45 days (or as required by law) minus any outstanding charges such as termination fees or fines. Early termination charges may apply under contract terms - for example, for a 36‑month monitoring contract ADT’s terms indicate a possible fee equal to 75% of the remaining monthly service charges for the initial contract term. Some third‑party sources reference a money‑back guarantee or rescission rights, but these claims are not clearly defined in ADT’s public terms and may require escalation to verify.

Your consumer rights in Canada

If your ADT contract falls under federal Direct Sellers Harmonization rules (applicable to certain direct‑sales contracts), you generally have an absolute right to cancel from the contract date until 10 days after you receive the written contract or cancellation‑rights statement; the seller must refund any required amounts within 15 days of cancellation. ADT’s own terms also state the security deposit refund timeframe (45 days) and that prepaid service terms are not refundable. If you believe federal or provincial consumer protection rules apply, consider citing the federal Direct Sellers Harmonization guidance when you request a refund or cancellation. For reference see Canada - Direct Sellers Harmonization.

Customer experiences

Customer reviews are mixed. Some users report positive interactions with knowledgeable agents. However, many complaints focus on difficulty cancelling (long hold times, transfers, and cancelled requests not being processed), recurring billing after attempted cancellations, and customer service responsiveness. Trustpilot reviews in Canada show an average rating near 2.8/5 with frequent billing and cancellation problems reported, and user forums include repeated accounts of lengthy escalation to obtain written confirmation or refunds.

Documentation checklist

  • Account number and full account name
  • Order confirmation email or contract copy (save PDF or screenshot)
  • Dates and times of cancellation calls and the names/IDs of agents, plus call reference numbers
  • Payment receipts and proof of prepaid terms or security deposit
  • Copies of any written cancellation request or mailed notices (certified mail tracking number if used)
  • Screenshots or copies of billing after cancellation, if it occurs

Common mistakes

Common pitfalls include assuming online or verbal requests will cancel service without confirmation, not requesting written confirmation or a cancellation reference number, and failing to document calls and dates. Some customers wait until the last day of a monthly term rather than calling early enough (DIY/self‑setup requires a 30‑day notice before the term end), which can result in another month of charges. Another frequent issue is expecting a prorated refund when ADT’s terms state prepaid service terms are not refundable; not checking contract termination clauses can lead to unexpected early‑termination fees.

Comparative recap

Method Refund Difficulty
Call ADT (standard residential: (888) 392‑2039) No refund for prepaid service term; security deposit refundable per terms; early termination fees may apply Moderate - High (reports of long hold times and transfers)
Call ADT (DIY/self‑setup: 1‑800‑238‑2727) No refund for prepaid service term; must give at least 30 days' notice before current monthly term ends Moderate - High (procedural requirement and reported delays)
Online/verbal attempts without documentation Unclear/none - often ineffective; ADT states cancellations cannot be completed online High risk of failure (many user reports of ongoing billing)

After cancelling

After you cancel, keep all confirmation emails or reference numbers and monitor your bank or card statements for any unexpected charges. If billing continues despite cancellation, escalate with ADT customer service, provide your cancellation documentation, and consider contacting your payment provider to dispute charges if appropriate.
