We Don't Just Install Security Systems. We Protect Toronto Families.
A locally owned, family-run security company serving the Greater Toronto Area since 1990. Licensed technicians, no subcontractors, no cookie-cutter packages.
From One Toronto Neighbourhood to the Entire GTA
Three and a half decades of protecting Toronto homes and businesses, one installation at a time.
Founded in Concord, ON
Mark founded General Home Systems in Concord, Ontario with a simple mission: give Toronto families real security from people who actually know the GTA. No call centres, no national franchises, just honest local expertise.
Growing with Toronto
As the GTA expanded, so did we. From Richmond Hill to Mississauga, Markham to Burlington, we followed our customers and built a reputation for custom-designed systems that the big national companies simply couldn't match.
Toronto's Trusted Name
10,000+ installations later, GHS remains family-run and locally focused. Every call is answered by someone who knows the GTA, every system is designed by a certified technician, and every customer gets Mark's personal guarantee.
GHS by the Numbers
What Makes GHS Different
Six reasons Toronto homeowners and business owners choose us over national security chains.
Local Toronto Company
Not a franchise, not a national chain. We're a real GTA company with real local people who know your neighbourhood and your community's specific security needs.
Licensed and Insured Technicians
Our own employees, never subcontractors. Every technician is licensed, insured, and trained in-house. You know exactly who is in your home.
Custom-Designed Systems
No cookie-cutter packages. Every system is designed from scratch for your specific property, layout, and security concerns. You get exactly what you need, nothing more.
Same-Day Emergency Response
Security issues don't wait. When you call, a local GHS technician responds the same day across all 30+ GTA communities we serve. No waiting days for a technician from out of town.
3-Year Workmanship Warranty
We stand behind every installation with a 3-year workmanship warranty. If something isn't right, we make it right. No questions, no excuses, no charge.
No Long-Term Contracts
Month-to-month monitoring, cancel anytime. We earn your loyalty through exceptional service, not through locking you into multi-year contracts with penalties.
Why Toronto Homeowners Choose GHS Over National Security Companies
The difference between a local security expert and a national franchise is night and day.
Real People. Real Expertise. Real Toronto.
General Home Systems is a family-run Toronto business. Mark founded GHS in 1990 and still leads every major installation personally. When you call GHS, you're talking to the people who will actually show up at your door.
Integrity
We give honest advice and recommend only what you actually need. No upselling, no fear tactics, no inflated quotes. Our reputation is built on doing right by every customer.
Excellence
Every technician is certified, every installation is inspected, every system is tested before we leave. We hold ourselves to the highest standards because your family's safety depends on it.
Community
We live and work in the GTA. Our technicians are your neighbours. When we protect your home, we're also investing in the safety of the communities we call home.
"I started GHS because I believed Toronto families deserved better than what the big companies were offering. 35 years later, that belief hasn't changed. Every system we install, I stand behind personally."

What Toronto Homeowners Say About GHS
Real reviews from real Toronto customers
"General Home Systems transformed our home security. The AI-powered cameras are incredible, we no longer get false alarms from shadows or animals. Mark and his team were professional, knowledgeable, and installed everything perfectly. Highly recommend!"
"We needed a comprehensive security system for our warehouse. GHS installed LPR cameras, access control, and 24/7 monitoring. The system has already prevented two break-in attempts. Best investment we've made for our business security."
"After a break-in attempt, we called General Home Systems. Mark came out the same day, assessed our vulnerabilities, and designed a custom solution. We feel so much safer now. The night vision cameras are amazing, crystal clear even in complete darkness!"
