I've been here 60 times and never written a review? Odd.
The airport seems to be under a never ending amount of construction. When I moved to Toronto in 2008 they were in the process of tearing down terminal 2, expanding terminal 1, and building the parkade at the end of the tram line. When I moved back to Calgary in 2013 they were starting improvements for the PanAm Games. Now coming back to visit in 2016 there's stuff going on in Terminal 3.
The improvements they've made over the years have been good, but it would be nice to visit the airport for once and not have to worry about detours, rerouting to get to your gate, and the added stress the construction can add to everyone else around you just trying to get through security.
