what the "$%$%$%"
Having flown in this area quite extensively, I can only ask.......
How does one not realise overflying a metropolis like Toronto? Smiths Falls is a very small rural town with a local airport. Brampton is a suburb of Toronto at the very northern edge. CYYZ is in the middle of the concrete jungle.
I've overheard the terminal controller handle many a/c in this type of predicament.
