Alberta's protection of source water is largely done through a voluntary mechanism. There are watershed groups that are funded by the province and they develop watershed management plans that are more guiding policy than enforceable under Alberta's Water Act.
One suggestion we made to Canada during the engagement on this bill was that, if there is a major project upstream from a first nation, there would be something in this bill that couples it with a trigger under the Impact Assessment Act. For example, the premier of Alberta and the cabinet are about to have a decision to make on a brand new dam on the Bow River between Calgary and Cochrane. That impacts the only first nation that's downstream, which is Siksika.
I think similar issues would apply to every first nation. If they're making water management decisions or deciding on projects that affect the source water of a first nation, then there should be a full federal review involved in the project.
