Perhaps I'll start. Thank you for the question.
I'll turn back—and you'll get copies—to the federal marine protected areas strategy. It helps to clarify the different roles that the different types of marine protection instruments provide.
As I mentioned previously, Parks Canada looks at the 29 marine regions with the intent of representing each of those regions with as good a marine conservation area as possible, one that's really representative of that area and captures the key unique features of those areas. Other marine protected areas—not to speak for the other agencies—may be looking at a specific highly productive area, for example, for the purpose of protecting future fish stocks.
It's driven primarily by purpose. The purposes of Oceans Act marine protected areas are in some ways different from the purpose of national marine conservation areas. NMCAs are about representativity, and they're also about identifying areas where they can contribute to the sustainability of coastal communities and lend themselves, to a degree, to having Canadians have opportunities to visit and experience them.
