Thank you for the question.
I can add from a health perspective, as you rightly pointed out, that science evolves over time and new health and environmental risks can be identified for chemicals. Oftentimes, Health Canada will develop new standards based on that new science, and that is made available to custodians as a basis to then identify new risks that may be present at their sites. I think that linkage between emerging science, emerging risks, and custodians to identify what risks may be in those areas, as well, will help identify.
