Indeed, Health Canada plays an important role in supporting custodians in remediating and identifying contaminated sites by way of leveraging its science-based programs, whether they be for air pollution, drinking water, chemicals or foods.
Guidelines, advice and technical input are provided to custodians so that they are well aware of the levels of risk that may be present from exposures at contaminated sites and what levels would be considered levels that would reduce that risk over time.
Leveraging that very robust science-based program at Health Canada, I think we're fully confident that the advice and guidance we provide to custodians does reflect consistent and tangible guidance that is reflective of current science on the health effects of these pollutants.
