So this is called overflights if my memory is correct and we do charge each and everyone of them a fee collected by NavCanada. I'm not 100% sure on this but we run this as a non profit.

I think you have no fucking idea what a tarrif is.

Not only does Canada already do this it's fees are far higher than the United States for large aircraft and they don't waive the fee if the plane is taking off or landing in the country like the United States and Mexico do. They also charge out the ass for using their airports.

What kind of news is this?

I don't think Canada can do that. There's an airspace treaty signed by basically everyone except Russia and China that gives a lot of rights on aerospawce to airlines companies but I don't remember the details

lets wait til the new congress is seated before we make any big decisions....
