I'll start with that.
In terms of substitution, there's been a big uptake from British Columbia. They've been the first province out of the gate to have discussions with the Canadian Environmental Assessment Agency. They have landed on agreements for substitution on five projects so far. I could provide a list of those projects for you, if you're interested.
I know there are other provinces that are interested, but they haven't reached the point British Columbia has in having formal agreements in place for substituted processes.
