My argument is not with allowing jets per se, but the expansion of the runway that would be needed to accommodate them.
I also get irritated by businesses that start up shop knowing that they'll have to operate under certain restrictions and then bitch and complain about those restrictions limiting their operations.
There's too much of this "yes we agreed to certain conditions but they are proving to be inconvenient so we're going to ignore them" going on in Toronto at the moment.
