Wait a second. Isn’t that going to extend into Canadian airspace? Lake Erie is less than 70 miles wide. It’s closer to 50 miles from Cleveland to the Canadian shore (one web site says 54 miles). So it looks like about a 7 mile violation of Canadian sovereignty.
No.
US airspace restrictions affect US airspace, stop at the border. However, we can have shared restrictions, meaning the FAA coordinates with the CAA and they may have agreed to the restrictions we asked for.
