I think that's an important issue. Right now it's more or less ad hoc, depending on the specific issues that emerge, particularly in the Arctic.
If you ask who is responsible at the bureaucratic level for the Arctic, the answer is everyone. If everyone is responsible, no one is responsible. Government needs to rethink how it's going to organize to ensure that the various agencies—and this ranges from the Defence department to Transport Canada, the Coast Guard, Health, Industry, Foreign Affairs, etc.—all have a piece of the pie, and that needs to be looked at seriously.
I understand that government never likes to do this big reorganization, but we have to remember that we are structured for a world that no longer exists, with the Arctic as a function of climate change. This coordination and co-operation needs to be developed quickly.
