multiple layers of tiles
Asbestos was heavily used in Canada until 1980. Starting in 1981, the government introduced a number of regulations and measures to reduce use of asbestos. From there, we saw a sharp drop in the number of asbestos containing materials produced after 1981. Unfortunately, it is still quite common to find asbestos in houses built after 1981. Just recently, LCS Laboratory found asbestos in floor tiles collected from a house built in 1985. My guess is, that a contractor used an old stock of supplies. We also observed a possible case of asbestos in 1990s popcorn ceiling, but the building was much older, so it is not clear where the asbestos came from. The final ban on use of asbestos in Canada came only in 2018 .

We just had our stippled ceiling tested with LCS and it came back positive for asbestos–our home was constructed in 1992 as part of a large residential development in Ontario. Year of construction does not appear to be a reliable indicator in determining the presence of asbestos.
