I guess there are two aspects to opting in. One is bringing another water into the act, and that would be at the request of a province if they thought a particular waterway was to be in the act. They would make a request to the minister, the minister would consider it, and then there would be a Governor in Council approval to change the schedule of the act.
The other one is for a specific work. If a constructor of a specific work for reasons of greater certainty wanted to ensure they had an approval under the Navigation Protection Act, they could come to us and ask us to review their plans. Then we could do so and issue an approval, and it would have the coverage of the act.
