UL-Approved Monitoring Station
Locally Operated
Residential + Commercial
24/7 Live Response
Security You Can Actually Reach
When the alarm goes off in your Barrie home or business, you don’t want to navigate a call centre on the other side of the continent. You want real people, watching in real time, dispatching the right response in seconds.
That’s what Grand Alarms has delivered across the GTA and Simcoe County for decades. From Alcona to Midhurst, Stroud to downtown Barrie, our technicians install, service, and monitor security systems that are engineered for how you actually live and work – and backed by a UL-approved monitoring station we control ourselves.
What We Protect in Barrie
Home Alarm Systems
Burglar alarms, door and window sensors, motion detection, smoke and CO monitoring, and smart-home integration. Whether you’re building new in Mapleview or upgrading an older home in the east end, we design a system around your floorplan – not a one-size package.
Business & Commercial Security
From retail on Bayfield Street to warehouses off Highway 400, we secure Barrie businesses with commercial-grade intrusion alarms, access control, and 24/7 monitored response. Built to meet insurance requirements and to scale as you grow.
Security Cameras & Video Surveillance
4K IP cameras, NVR recording, remote live view from your phone, and AI-assisted alerts that tell the difference between a person and a passing car. Installed clean, configured correctly, and actually usable when it matters.
Why Barrie Chooses Grand Alarms
UL-Approved Monitoring Station.
Signals from your Barrie property are received, verified, and dispatched by trained operators held to UL standards – not a generic overseas call centre.

Frequently Asked Questions
Everything Barrie homeowners ask before choosing a system. All FAQs are marked up with schema for Google rich results.
How much does alarm monitoring cost in Barrie?
Our monitoring plans start at competitive monthly rates with no long hidden contracts. Exact pricing depends on equipment and whether you need cellular or IP signalling – ask us for a plain-language quote.
Can Grand Alarms take over my existing alarm system?
In most cases, yes. We offer alarm takeover for Barrie homes and businesses currently monitored by ADT, TELUS, or other providers – often with no new equipment needed.
Do you install security cameras without a monitoring contract?
Yes. You can have cameras installed as a stand-alone system, or combine them with monitored alarms for full coverage.
Is your monitoring station actually in Canada?
Yes – and it’s UL-approved, meaning it meets stringent standards for alarm response, redundancy, and operator training.
Do you service commercial properties in Barrie?
Absolutely. We design and install commercial intrusion, access control, and video surveillance systems for retail, industrial, office, and multi-tenant buildings throughout Simcoe County.
How fast can you respond to a Barrie service call?
Because we operate across the GTA and north into Simcoe County, most Barrie service requests are scheduled within a couple of business days – sometimes same-week for urgent issues.
