Worst Security Service

Signed on with ADT in 2014, there were constant issues of false alarms including receiving 5 am phone calls from ADT while we were travelling; we then sent friends to look at our house and nothing had happened. I received a letter from ADT cancelling my service for system issues - once again faulty ADT equipment. Because it was a break of contract, they are saying that I have to pay the cancellation fee even though it was ADT who broke the contract. Bunch of con artists hiding in a corporation.

Home security system

This company's left hand doesn't know what it's right hand is doing. They messed so much up that they gave me a 6 month credit, which they have now messed up and I haven't received despite a couple a months of phone calls, fails to follow up on calls back, and totally unhelpful people on the phone. Despite a great deal of patience, they have shown no interest in making things right or following through on what they say they will do. So many lost hours and frustrations.

Home alarm monitoring

I alarm service with reliance protectron and signed a 5 year service contract in 2012. In 2014 adt purchased protectron. I didn't sign a new service agreement with adt, or authorize adt to continue service promised by reliant. Adt is now coming after me for balance of a contract that was signed with a completely different company. Not Happy!!

Alarm installation

I am very disappointed in the alarm installation and follow up service (or lack there of) from ADT. The previous alarm was ripped out unnecessarily causing willful damage to the previous contractors equipment. In addition, when I called to ask about this or about the contract no one will return my calls after several attempts. Do not go with ADT.

Alarm services poor

I got invoiced over 2 years ago for a service they couldn't provide (installation problems) but kept on billing me eventhough i cancelled the damn services from day ZERO. it's over 2 years and ADT's accounting department cannot seem to get it right. I just got an invoice today that states it is 619 days overdue!!! I would never recommend this company to anyone i know. Even my maintenance team was wanting to change the security monitoring from Chubb to ADT and because i look after the area, i would not approve. Sorry ADT, you lost a big contract with me and the company! All this trouble for $400.00. i think i have wasted over $400 in my time and should be billing them back!

Our house was broken into when we were on vacation. ADT was quick to respond to our request. Very effecient. Easy to operate alarm. Have peace of mind and secure feeling whenever we are not home.

First Review


installation of security system

Shane took hours longer than expected, took personal calls, forgot all his equipment and then told me he was going to take a break! I was very disappointed. The sales lady was awesome and the overall company service was good. This installer was not.

More about ADT Calgary

Our story
For over 125 years, we’ve made protecting and connecting the centerpiece of what we do.

First security system network
It all started on April 5, 1874, with a nighttime break-in. American District Telegraph (ADT) founder Edward Callahan created a telegraph-based “call box” to signal for assistance to a central office. He quickly connected 50 other homes in the neighbourhood, creating the first residential security system network.

1890-1920: R​​oundsmen
ADT introduced the first proactive security monitoring and response service, employing roundsmen to make rounds each night of customers’ homes to help prevent crime before it happened.

ADT’s first president
Robert C. Clowry was ADT’s first president. He was also a colonel in the US military. He worked his way up from messenger boy, eventually serving as president of both Western Union and ADT which he led for eight years.

Central monitoring centres
ADT pioneered the concept of the central monitoring centre, enabling thousands of customers to link to 24/7/365 monitoring and protection.

First burglar system
ADT started its first big expansion in the 1940s after pioneering the first automated burglar system. At the same time, ADT installed the first automated fire alarm system providing immediate response to fire.

Secured by ADT
A new ADT security feature gained immediate customer approval: the iconic ADT yard sign which now dots thousands of yards across the country.

Reliance Protectron
In July 2014, ADT purchased Reliance Protectron Inc., at the time Canada’s second-largest security services provider with 400,000 customers from coast to coast.

ADT Interactive Services
ADT elevated home intelligence when it launched Interactive Services, the app that lets customers remotely access and control their home security system, as well as lighting, climate control, video surveillance and much more..

Creating customers for life
Much has changed since our humble beginnings in 1874. One thing that hasn’t is our desire to constantly improve. So we combined forces with Protection 1 to further raise our standards for customer security and service.

In Canada, we’re headquartered in Montreal and Toronto. With our network of qualified professionals specializing in the installation, servicing and monitoring of security and smart home automation systems, we serve more than 800,000 residential, commercial and industrial subscribers across the country.

Alarm Systems
Our monitoring services protect you regardless of the danger. Intrusion monitoring A home intrusion not only means the theft of your belongings. Even if they are insured, nothing can replace their sentimental value. An intrusion also leaves a sense of violation. Our state-of-the-art monitoring centres keep an eye on your home 24/7 and are ready to respond when an alarm occurs. Nowadays, being at home is no longer a deterrent to theft. That’s why we are there for you at all times! The intrusion monitoring service is included in all our packages. Fire monitoring Help protect your family and home from fire and smoke! Even if you have smoke detectors, who will call the fire department when you are out? And since smoke is toxic, what will happen if you are there but sound asleep? Choose our fire monitoring service! Our monitoring centres can call the appropriate emergency services when you are away from home or are unable to answer. The fire monitoring service is included in all our packages. Emergency services Request assistance from emergency services directly using your keypad or optional wireless emergency button! Better yet, this service is FREE with the intrusion monitoring! Flooding monitoring Be notified of flood risks to help reduce or prevent damage caused by water! An appliance that stops working, a pipe that is frozen or punctured, or a damaged sump pump: you’re protected! Carbon monoxide monitoring Protect yourself and your loved ones against carbon monoxide. Odourless and colourless, this gas is impossible to detect. Our detectors help protect you by alerting you to the presence of this dangerous gas and immediately notifying our monitoring centres. Monitoring of extreme temperature fluctuations Being informed of abnormal temperature fluctuations can help prevent pipe damage caused by frost. This will help you prevent frozen pipes from bursting, which can often happen if your home’s central heating system breaks down.
​An outstanding network of monitoring stations We own and operate a nationwide network of three monitoring stations which are interconnected for complete redundancy. In the event of a major power outage or a natural catastrophe, all alarm signals are automatically forwarded to another station to ensure uninterrupted service. ADT monitoring centres map Five Diamond Certification: Our monitoring stations have earned the Five Diamond Certification from The Monitoring Association (TMA, formerly known as the Central Station Alarm Association), one of the most important governing bodies in the alarm industry. This means our central station operators, who are the first line of defense in emergency response, undergo regular professional training and maintain high performance levels in alarm response handling. Underwriter Laboratories Certification (ULC): We have monitoring stations which are ULC certified and comply to strict national standards regarding security system installation and alarm response handling.
