Ottawa residents living in condos and highrise buildings should take note of a troubling incident unfolding in Toronto this week — one that highlights just how unpredictable and persistent fire risks can be in multi-unit buildings.
What Happened in Toronto
A fire broke out between the walls of two Thorncliffe Park condo towers in Toronto after crews were performing remedial work to repair damage from a previous blaze that burned for several weeks late last year. According to Toronto Fire Services, the new fire was ignited during that very remediation process — a sobering reminder that fire risk doesn't end when the flames are put out the first time.
The Thorncliffe Park towers have now faced two fire incidents in a short span, with the second one emerging from what should have been a recovery effort. Investigators are looking into how sparks from repair work reignited within the building's wall cavities.
Why This Matters for Ottawa
Ottawa's skyline has grown considerably in recent years, with dozens of new condo towers rising in areas like Centretown, Hintonburg, Westboro, and along the LRT corridor. As more Ottawans choose highrise living, understanding the fire risks specific to multi-unit buildings becomes increasingly important.
Wall cavity fires — fires that travel unseen between floors or units — are notoriously difficult to detect and contain. By the time visible smoke or flames appear, a fire may have already spread significantly through a building's structure.
What Ottawa Condo Residents Can Do
Ottawa Fire Services recommends that all condo residents familiarize themselves with their building's evacuation plan and ensure their unit's smoke detectors are functioning. Here are a few key tips:
- Know your exits. Walk your building's stairwells and identify at least two exit routes from your floor.
- Don't use elevators during a fire. Always take the stairs during an evacuation.
- Report repair work to your condo board. If contractors are doing remedial or renovation work in your unit or building, ensure proper fire watches are in place.
- Check your insurance. Condo insurance should cover both your unit's contents and any liability in case of accidental fire.
Building Management Accountability
The Toronto incident also raises questions about oversight during building repairs. When fire damage occurs in a shared wall or mechanical space, remediation work must be conducted with care — hot work permits, fire watches, and proper containment are standard protocols that can prevent exactly this kind of secondary incident.
Ottawa condo boards and property managers overseeing any repair or renovation work following fire or water damage should ensure that all contractors follow proper hot work safety protocols as outlined by the Ontario Fire Code.
Stay Informed
For Ottawa residents, the Ottawa Fire Services website offers free home fire safety resources, and building managers can request fire safety inspections or consultations through the city. Don't wait for a close call to review your emergency plan.
