I'll start, and then I'll turn it over to my colleague from the Canadian Environmental Assessment Agency to follow up.
You've touched upon a main aspect of the proposal we've provided today. I think the committee would be aware that provinces have been asking for some of the tools we're talking about today for quite some time.
What we're talking about are elements known as substitution and equivalency for us to harmonize practices better with the provinces. Of course, there are protection measures in the bill to ensure there are safeguards, that we're not going at this in sort of a holus-bolus way, but really it's to work better with the provinces.
Helen, I will turn it over to you to follow up on how substitution would work in particular.
