Some MPAs work; others don't work. There was the study that Dr. Côté referenced about the five criteria that make MPAs successful and the follow-up study that I referenced—and will send around—about the importance of staffing and funding. If you take those two studies together, you understand very comprehensively, globally, what makes some areas work and others not work.
I don't think there is any clear evidence that MPAs can cause damage for the entities they try to protect, but sometimes they're just ineffective. We know exactly why they can be ineffective and we know how to address it. We can learn in Canada from the mistakes other nations have made and do something that's strong and robust here.
