We have a shared role in that. Transport Canada sets out the regulatory structure within which it takes place. The coast guard is the operations group, taking the information and relaying it to the appropriate bodies, be they Transport Canada or the maritime security operations centres. If there's then a desire to take action, and the need to take action, that would be streamed to whatever department or agency had the lead role for whatever the issue was, and the coast guard may or may not be asked to support that department.
