If you stumble in to the airport half asleep at 6am like me, the line up at Tim Horton's at the start of section 'C' can seem a little daunting. And Starbucks at the end of section 'C' looks really far away, especially if you need to be in section 'B'.
If you push on, bagels await you at the start of Section B. There were a bunch of breakfast options for $6ish, and made fresh to order. From memory mine had ham, egg and cheese on a toasted jalapeno bagel and it was pretty tasty for airport food. Actually better than I was expecting! There's also brewed coffee etc if you're not hoping to sleep on the plane...
