Epigenetic effects refer, really, to the impact that certain traumas can have on generations going forward, even if the specific harm is not ongoing. When it comes to first nations communities, not only was there historical trauma, but there are ongoing harms as well, and so both of those circumstances apply in this situation.
I think it will be critical to have first nations' voices front and centre in the consultation around the regulations, making sure that their self-determination is consistent with the UNDRIP requirement that those voices are heard and valued in the regulations and in the decision-making about how costs should be assigned.
