Thank you, Mr. Chair.
I want to thank all of the witnesses here today. Your testimony is certainly appreciated, and your time.
I guess my first questions would be for Mr. Gibson and Mr. Irving, and anybody else who wants to jump in. You talk about hydro dams and the high-head issues that are connected with those.
We've recently seen some changes on the Columbia River system, which flows initially out of British Columbia down through the U.S. They've made some significant changes to fish passage there, to where we now see a significant return of sockeye salmon in the lower Okanagan system.
I'm wondering if mitigation improvements to existing structures to allow better fish passage would be considered part of the offsetting requirements for new projects. Can you tell us if those types of improvements on an existing or a grandfathered system would be considered?
