Upon its development, this was the first airport terminal project in Canada to go through the LEED registration process. The terminal design had sustainability in mind from its beginnings. A diverse project committee was put together to review the costs and benefits of 36 potential technologies/strategies for the terminal design. Those chosen were incorporated into the design to reduce the terminal's environmental impact included a high-performance building envelope, high-efficiency lighting and mechanical systems, and large roof overhangs to reduce solar gain.
