For pilot trinkets, try the Dehavilland Store in the cafeteria across the parking lot from Flight Safety open tuesdays and thursdays at 1100 am.
They have deHavilland hats at the museum on the north end. Talk to the Chilean shuttle driver, and on a slow day, he'll run you up if you're just going to the store.
If you're really on a roll, there's a watch store in the YorkDale Mall with 7000 dollar pilot watches.
