Please be advised that on Feb. 3 beginning at 8 a.m. until Feb. 4 at 4 a.m. construction activity in Concourse C will reduce the number of available security screening lanes. This may result in longer than normal security wait times for travellers who are departing out of Concourse C. Please ensure you allow extra time to go through the screening process. We appreciate your patience as we work to improve your travel experience through YYC.
