Sir, I believe you're very aware of the different responsibilities for search and rescue on the land, at sea, and in the air. On the land, provincial and territorial authorities supported by law enforcement take the lead and are responsible for land-based search and rescue. It's the coast guard in the maritime domain and then the Canadian Forces in the aerospace search and rescue domain.
The network of search and rescue partners is very alive and very practised at collaborating and cooperating and bringing different assets to support the different search and rescue leads, be they land, maritime, or air.
