If passed, the Radon Awareness and Prevention Act, 2014, would trigger changes to the Ontario Building Code and require owners of enclosed workplaces that are not projects to test for, and mitigate, high radon levels or face potential penalties. For radon levels in the 200 to 600 Becquerel-per-cubic-metre range, Health Canada prescribes a two-year timeframe for taking steps to mitigate the risk. For radon levels of more than 600 Becquerels per cubic metre, the federal agency shortens its prescribed timeframe for taking steps to mitigate the risk to one year. Bill 11 would require owners of workplaces whose testing reveals radon levels exceeding 200 Becquerels per cubic metre to take “reasonable action” to reduce radon levels within a two-year window. The Ontario Lung Association is hoping to have input at this stage.
