Sure.
You can ask Senator Dawn Anderson. The Chinese were up to look at the marine infrastructure in Tuktoyaktuk. That was the jumping-off point for all the offshore drilling that happened in the Beaufort Sea and in all of the offshore around Inuvik and Tuktoyaktuk.
We had the Russians fly across the Arctic with private airplanes. We call those “amphibs”. They're amphibious aircraft and will land on the runway and on water, and they happened to follow the North Warning System.
We've had Chinese from the Chinese embassy in Ottawa come through Inuvik. The RCMP tried to identify them, but we'll leave that one alone.
