Yeah. While no country 'owns' international airspace, it has been divided into jurisdictions for the purposes of ATC. Like the US has most of the Northern Pacific Ocean run out of Oakland Center, a huge chunk of the Atlantic run out of New York Center. Canada and Ireland have most of the North Atlantic out of Gander and Shanwick.

I know. I flew LAX-HNL quite a bit. Oakland Oceanic is designated by ICAO, just as Shanwick is.
