Smoke Detector Installation
In the event of a fire, every second counts. Properly installed smoke alarms are vital for your safety. Our team installs detectors on all levels of your home and outside bedrooms to give you the earliest possible warning. We recommend units with battery backup for maximum reliability. Regular checks are also important to ensure your alarms are working as intended.
Signs your smoke alarm may need service:
Testing is simple: create a small amount of smoke near the detector. If it doesn’t sound immediately, replace the batteries or contact Ontime Electric for a quick inspection.
Ontario Carbon Monoxide Detector Law
In Toronto and across the GTA, the law requires smoke and CO protection in homes with fuel-burning appliances, fireplaces, or attached garages. For condos and apartment buildings, alarms are also required in service rooms and in suites located next to those rooms.
Key requirements under the Ontario Fire Code (effective Jan 1, 2026 – City of Toronto ):
- Installed on every storey of the home
- Placed outside all sleeping areas
- Carbon monoxide detectors installed where fuel-burning systems are present
- Must meet CSA/ULC standards
Annual inspections of fuel-burning appliances and vents are recommended. We ensure your Smoke & CO alarms are installed in full compliance with Ontario Fire Code requirements, giving you reliable protection and peace of mind.
Combo Smoke & Carbon Monoxide Alarms
For complete protection and convenience, consider combo Smoke & CO alarms. These units detect both fire & CO, can link with other alarms, and are CSA/ULC-certified.

- Alerts for both fire and carbon monoxide (CO)
