Thank you for your question.
Yes, research is under way, but the findings haven't been released yet. The idea is to deploy a number of sonobuoys to determine the location of the whales through triangulation. That information will tell us where the closure should be put in place. If the whales are in another area, the area where they are no longer present could be reopened.
Advancements are being made and research is under way, but it's a lengthy process. Acoustic technology has been around for a while, but no significant progress has been made. The needs are what is driving that work, and the potential is certainly there.
I think the Government of Canada should encourage that work, which could help fishers choose appropriate fishing grounds.
