I didn't plan on speaking to this, but I will add my experience.
When I was the chief of enforcement, there was a lot of disagreement within the Department of Justice on whether or not you could bring an environmental action against the Government of Canada or the crown, Her Majesty in right of Canada. They then determined that yes, indeed you can, and they made the decision that they would make it clear in all environmental law thereafter that those laws are binding on Her Majesty in right of Canada, and that's why it's precisely stated. It simply means that you can bring an action and the Government of Canada is bound by the provisions of that statute.
