Thank you so much for the question.
I would say that Canada has done a better job of framing.... Where TSCA has not necessarily deemed substances to meet their threshold where their restrictions necessarily come into play, the CEPA toxic...is quite a useful tool for triggering criminal and other powers, which the federal government is then able to use for substances that meet our toxic substances threshold.
I would say that we do have some very useful and powerful tools. Unfortunately, those tools aren't necessarily all put to use in managing chemical substances.
