If your Waterloo home was built before the mid-1980s, particularly in older neighborhoods like Uptown Waterloo, Westmount, or Lakeshore built through the 1960s and 1970s, popcorn ceiling texture applied then commonly contained asbestos fibers for fire resistance, sold legally in Canada until that point. Homes built after the mid-1980s in newer subdivisions like Columbia Forest or Vista Hills carry much lower risk, as manufacturers phased out asbestos by then. You cannot tell by looking. Lab testing, $300 to $500, is the only way to confirm before any sanding, scraping, or renovation disturbs the ceiling.
