What is included in a commercial fire alarm inspection?
An annual fire alarm inspection under CAN/ULC-S536:2019 covers every device on the system, plus the monitoring station, plus the documentation that goes to your AHJ:
For a typical commercial office of 50 to 100 devices, this is a 4 to 6 hour visit. For a 30-storey condo with 1,500 or more devices, it is a 2 to 3 day engagement, often scheduled in phases to minimize tenant disruption.
How often must commercial fire alarm systems be inspected in Ontario?
The Ontario Fire Code defines a layered cycle. Daily, building staff confirm the fire alarm control unit is in normal status with no trouble lights. Monthly, building staff rotate through manual station tests, check audible and visual signals, review trouble signals, and inspect backup batteries. Annually, a CFAA-certified technician performs the full inspection with 100% device testing. System changes trigger a separate CAN/ULC-S537:2019 verification.
Mandatory date: Under O. Reg. 87/25, compliance with CAN/ULC-S536:2019 became mandatory on January 1, 2026. Older systems operating under earlier versions of the standard need to align with the current version.

CAN/ULC-S536:2019, Section 1.1
- CAN/ULC-S536:2019 is the inspection and testing standard. It defines what gets tested, how often, and what the report looks like.
- CAN/ULC-S537:2019 is the verification standard for new installations and major modifications.

- NFPA 72, the National Fire Alarm and Signaling Code, is referenced for certain technical specifications.
- Ontario Fire Code (O. Reg. 213/07, amended by O. Reg. 87/25) is the regulation that gives all of the above their legal force in Ontario.

Who is qualified to inspect commercial fire alarms?
A technician holding current Canadian Fire Alarm Association (CFAA) certification recognized by the Authority Having Jurisdiction. CFAA is the credential AHJs across Ontario use as the competency benchmark for fire alarm inspection. CAINtech technicians are factory trained on Siemens Fire Alarm Systems, and have experience working on third-party systems like Simplex, Mircom, Notifier, Edwards (EST), and Fire-Lite, CAINtech technicians are trained on WHMIS,Working at Heights, and First Aid.
What does CAINtech do during a fire alarm inspection?
How does CAINtech handle deficiencies?
Critical deficiencies are life-safety risks such as an inoperable control unit, monitoring signals not transmitting, or a non-functional bank of notification appliances. These need immediate action; if repair cannot happen in time, the building needs a fire watch until the system is restored.
Non-critical deficiencies such as a single smoke detector that failed sensitivity testing are tracked, scheduled, and re-tested. Our annual report separates the two: critical items on page one with remediation timelines, non-critical items in a tracked log. For either category we provide a quote with a priority recommendation. Inspection service does not lock you into using us for the repair.
