I live in Canada and I'm in the process of planning my trip to Hawaii. For my flight back from Hawaii, I am planning to take the Air Canada flight Kahului-->Calgary-->Regina. The layover time in Calgary is 1 hr 15 min. I'm wondering if that's enough time for a layover, and what are the processes I need to go through there at the airport. I know that the Calgary airport has a new connections centre, does that allow me to avoid security check when connecting flights?
