Carbon Monoxide Poisoning in Ottawa Sends 10 to Hospital, One in Critical Condition

A running car in a closed garage is suspected to have caused dangerous gas buildup in a Vanier neighborhood home.

Emergency crews responded to a call at 9:15 a.m. on Granville Street in Ottawa's Vanier district, where 10 people were affected by carbon monoxide poisoning.
Six adults and four children were hospitalized, with one adult in critical condition and the remaining nine in serious condition.
Authorities believe a car left running in a closed garage caused the carbon monoxide buildup, affecting three connected housing units, though only one unit's occupants were hospitalized.
The family involved is reportedly new to Canada and may not have been aware of the risks associated with running a car in a closed garage without ventilation.
Ottawa officials and experts are urging residents to check their carbon monoxide detectors and ensure proper safety measures to prevent similar incidents.
