Fire Alarm Installation in Scarborough
Harex takes scheduled work in Scarborough for contract clients, typically multi-site owners who want one contractor and one set of records across Durham and the east GTA. Travel is billed, and a contractor local to a single Scarborough building will usually beat Harex on price for one-off work.
Toronto Fire Services. Scarborough is inspected by Toronto Fire Services' Fire Prevention Division, which inspects every occupancy type across the city's six Scarborough wards under the Fire Protection and Prevention Act. Toronto publishes fire inspection results for public buildings, and charges for inspection services under Municipal Code Chapter 441, so a Scarborough owner's record is more public and more expensive to re-inspect than a Durham owner's.
Harex forwards every completed fire alarm installation report for a Scarborough building to Toronto Fire Services, so the building is on record as maintained with the department that would otherwise be the one to notice a lapse. Scarborough is about 45 minutes from the Harex base in Oshawa; travel is billed, and a three-year contract fixes the rate for its term.
Harex also provides fire alarm installation in Pickering.
When you need this
Harex installs and verifies for a new build or addition, a change of use that puts your building under a stricter requirement. A panel that is obsolete, unsupported, or failing inspection year after year. Or a retrofit order from the fire department that you have decided to comply with.
How a project runs
- P-01Site review and scope.We walk the building, read the drawings or the order, and write the scope in plain terms with a fixed price.
- P-02Install to CAN/ULC-S524.Devices, wiring, annunciation and panel, staged around your operations so the building keeps running.
- P-03Verification to CAN/ULC-S537.Every device and every function proven and documented. This is the report the building official and your insurer want to see.
- P-04Handover and first annual.Staff shown how the panel behaves, records filed, and the building put on the annual inspection schedule so the clock never runs out.
Install or repair, honestly
We would rather repair a working system than sell you a new one. Where a panel still has parts and service life, we say so. Where it does not, we show you the deficiency history that proves it. And where a retrofit order looks unreasonable for a system that has passed for twenty-five years, we put that question to the fire department first. How we handle orders and disputes →

What clients say
across every platform
“Harex has looked after our alarm and extinguishers for years. They come when they say they will, and the report is in our hands before the insurer asks for it.”
“We were told the whole system had to be replaced. Harex asked the fire department why, in writing, and the scope came back a fraction of what we had been quoted.”
“We had thirty days and a list we did not understand. They went through it item by item, told us what was actually required, and we passed the re-inspection.”
“Four buildings, one schedule, one set of reports. I stopped chasing three different contractors for paperwork the month we switched.”
“Panel went into trouble on a Saturday night. Somebody answered, walked our supervisor through it on the phone, and had a technician there before the shift started.”
