North York Apartment Evacuated After Carbon Monoxide Leak; One Person Hospitalized
Emergency evacuation at North York apartment after carbon monoxide leak from basement boiler prompts health scare and highlights need for maintenance safety measures.

Residents of a North York low-rise apartment were awakened in the early hours of Thursday morning after an emergency evacuation was ordered due to dangerously high levels of carbon monoxide. The incident occurred at 3018 Keele Street, near Downsview Park Boulevard, with fire crews arriving just after 4 a.m. to assess the situation and secure the safety of all occupants.
First responders acted quickly upon detecting elevated carbon monoxide levels throughout the building. As a result, the entire structure was evacuated to prevent any further exposure to the colorless, odorless gas, which is known to pose serious health risks. Paramedics on site assessed multiple residents, with one individual being transported to the hospital for further treatment. The condition of the hospitalized resident has not been disclosed at this time.
Authorities believe that a mechanical problem was responsible for the dangerous leak, with initial findings tracing the source back to the basement boiler room. The nature of the mechanical failure is still under investigation, but officials are emphasizing the importance of regular maintenance for building infrastructure to prevent such hazardous situations.
While crews worked to ventilate the premises and restore it to safe conditions, Enbridge Gas representatives also arrived on scene to assist in addressing the issue and ensure there is no ongoing risk to residents or first responders. No timeline has been provided for when the building will be deemed safe for re-entry.
This incident serves as a critical reminder of the importance of functioning carbon monoxide detectors and robust emergency response plans in residential buildings. Residents are advised to remain vigilant and seek medical attention if they experience symptoms such as headache, dizziness, or nausea following potential exposure to carbon monoxide.
