⚠️ Hidden cameras and listening devices are being found in Montreal apartments, rentals, and offices at a growing rate.
Montreal Has One of Canada’s Highest Rates of Hidden Camera Discoveries in Rental Properties
Montreal is home to Canada’s most active rental market. With tens of thousands of furnished apartments, Airbnb units, and student residences in neighbourhoods like the Plateau-Mont-Royal, Côte-des-Neiges, and Mile End — the risk of encountering a hidden camera in a rental property is higher in Montreal than in almost any other Canadian city.
Beyond the rental market, Montreal’s thriving corporate sector — headquartered in the downtown core and the Saint-Laurent tech corridor — makes executive boardrooms and meeting rooms prime targets for industrial audio surveillance. Domestic surveillance following relationship breakdowns is also a leading reason Montreal residents contact us, particularly in the Westmount, Outremont, and Laval areas where high-value residential properties are common.
Under Quebec’s Act Respecting the Protection of Personal Information and Canada’s Criminal Code, recording someone without consent is a criminal offence. Our certified TSCM technicians have completed over 300 sweeps across Montreal Island, Laval, and the South Shore — helping clients from every walk of life confirm their privacy.
Do Any of These Describe Your Situation in Montreal?
Hidden surveillance devices are found across all walks of life. These are the four most common situations that lead Montreal residents to book a professional TSCM sweep.
Montreal Renters & Airbnb Guests
Staying in a furnished Plateau apartment, a Westmount condo, or an Airbnb anywhere on Montreal Island? Furnished rentals are the most common location where hidden cameras are discovered.
Separated or Divorcing Montreal Residents
Going through a separation or divorce in Montreal? Surveillance devices planted by an ex-partner in shared or previously shared homes are among the most common devices we find.
Montreal Business Professionals
Montreal’s downtown corporate sector and Saint-Laurent tech corridor handle sensitive negotiations daily. If confidential business information has leaked, your boardroom may contain an audio device.
Montreal Students & Young Professionals
With four major universities and a large young professional population, Montreal has a massive student rental market. Côte-des-Neiges, Rosemont, and Mile End units near campuses are frequently flagged by our clients.
Think Your Montreal Property May Be Compromised?
Don’t wait — hidden devices continue transmitting until they are found. Book a free confidential assessment and our Montreal TSCM specialist will respond within 24 hours.

The Most Common Hiding Spots Found During Montreal Property Sweeps
Hidden surveillance devices are designed to be invisible to the untrained eye. These are the specific locations our technicians check first in every Montreal property — because these are where devices are most frequently found.
Smoke Detectors
The most common hiding spot in Montreal rentals — the wide angle lens provides full room coverage from the ceiling.
USB Wall Chargers
Modified USB chargers with built-in cameras are frequently found in Montreal furnished apartments and Airbnbs.
Alarm Clocks & Radios
Bedside alarm clocks and clock radios provide perfect bedroom coverage — a common find in Montreal rental bedroom sweeps.
Picture Frames & Mirrors
Pinhole cameras concealed in picture frames or two-way mirrors are increasingly common in Montreal furnished properties.
Smart Speakers
Commercially available smart speakers can be modified to record conversations continuously — found in both homes and Montreal boardrooms.
Electrical Outlets & Power Bars
Modified wall outlets and power bars with hidden cameras or GSM transmitters — particularly common in Montreal office environments.
Ventilation Grilles
Ventilation grilles and air vents are commonly used to conceal audio recording devices in Montreal offices and residences.
Vehicle Undersides & OBD Ports
GPS trackers attached magnetically to the chassis or plugged into the OBD port are a growing concern for Montreal vehicle owners.

Montreal Client Experiences
What Our Montreal Clients Have Said
“I had been renting a furnished apartment in the Plateau for three months before I noticed something strange about the smoke detector in my bedroom. The team swept the entire unit and found a wireless camera inside it. The report was critical in my case against the landlord. Outstanding service.”
Sophie M.Client in Plateau-Mont-Royal, Montreal
“We brought Spy Device Detection in before a major acquisition negotiation in our downtown Montreal boardroom. They found a wireless audio transmitter that had been planted in the conference room weeks earlier. I cannot stress enough how important this service is for any Montreal business handling sensitive discussions.”
Laurent B.Business Executive, Downtown Montreal
“After a difficult separation, I moved back into my Laval home and had a persistent feeling something was wrong. The technician arrived in a plain car with no indication of who they were. Two hours later I had a full written report. I finally felt safe again. I would recommend this to anyone in Montreal.”
Isabelle T.Client in Laval, Quebec
