The requests come from a variety of stakeholders. There's no particular.... Most of them would come from stakeholders, but there are requests from elsewhere as well.
In terms of how we work with Environment Canada, I think we work quite closely with Environment Canada in a whole bunch of different ways. I don't have time to explain all of them, but suffice it to say that we do work closely with them.
Obviously the kind of thing we look to Environment Canada for is direction on what is important to collect, as we don't want to be the ones deciding what's important to collect. We're happy to collect what policy-makers think is important. That's how we look to departments like Environment Canada to help set that agenda in terms of what needs to be collected in terms of environmental information.
And we've done that by using various mechanisms. I've been at it now for 15 years, and at various points during those 15 years we've had fairly intensive discussions on what needs to be collected.
