How to protect yourself from deceptive door knockers.

We recognize that not all “door knockers” are bad. In fact, you may have joined the ADT Canada family after having met with one of our ADT door-to-door sales representatives or ADT Authorized Dealers. It’s unfortunate but we hear from our customers that certain competitors of ours employ deceptive sales practices to attempt to lure you away from or cancel your ADT security. So, we’ve put together this guide to make sure you are fully prepared when approached by a door-to-door salesperson selling home security.

Ask to see official ADT Canada company identification.

First and foremost, always confirm a sales rep or Authorized Dealer’s affiliation with our brand by asking to see official ADT company identification. If they do not show official ADT ID, don’t believe it. If in doubt, call us immediately at 800-653-9111.

Don’t give out your personal account information.

Until the sales rep has presented official ADT ID, be aware of questions about your personal information. Do not jeopardize your financial, medical or personal identity.

Don’t change your security provider without calling us first.

On rushed installations the equipment may be installed improperly, which may impact how your system is monitored. Improper termination of your account could leave you having to pay multiple monthly charges.



Listen for common "deceptive door knocker" phrases used to gain access into your home. Here are some examples of false claims from fraudulent door-to-door sales reps, and the truth behind them:

  • CLAIM: Your monitoring and customer care are being done from the US.
  • REALITY: Not true! ADT Canada has 3 ULC-certified monitoring stations located across Canada, providing bilingual support 24/7.


  • CLAIM: Your security system is not being monitored.
  • REALITY: We have live operators working 24/7 and Five Diamond certification. If you set off your alarm and cancel the alarm with a valid user code, only then will you not receive a call from an operator as a measure to reduce false alarms.


  • CLAIM: They can help you "cancel" your services.
  • REALITY: For security reasons, only you (the registered owner) can cancel your service with us, and this should be done by phone.


  • CLAIM: Only they can upgrade your security system for a competitive price.
  • REALITY: We offer a full suite of interactive security products and services. Call us to learn more!
