Ottawa's Aging Housing Stock Raises Asbestos Concerns
A significant portion of Ottawa’s housing stock was built during a period when asbestos was commonly used in construction materials. According to Statistics Canada, nearly 60% (243,080) of the city’s occupied private dwellings were constructed by 1990 or earlier. Health Canada notes that asbestos was widely utilized before this date for insulation and fireproofing purposes. Asbestos screening is increasingly relevant as property owners consider renovations, alterations, or demolitions involving older homes. Ontario Regulation 278/05 mandates an asbestos examination prior to such work if there's a potential disturbance of suspect materials. This requirement applies regardless of whether the material is friable or non-friable. The overlap between Ottawa’s aging housing stock and historical asbestos use creates practical implications for property owners, who are advised by local authorities like Health Canada and The City of Ottawa to consult professionals before undertaking any repair work on homes built prior to 1990.
