The new terminal at Pearson International Airport opened for business in 2004. It presents a clean modern facility that provides a spacious replacement for the recently demolished Terminal One.

The terminal boasts a clear, column free span across the departures level. This is achieved using a set of curved steel ribs that span across the building. The ribs were spliced in the centre to permit a smaller transportation length. A temporary steel support system was used to shore up the ribs, prior to the installation of the interim, departures level floor, which served to brace this "three hinged arch" type structure. The ribs rest on custom designed "wishbones" across the airside portion of the building.

The building is currently (2005) undergoing more expansion as a new departure/arrival gate extension is added, over the former site of the old Terminal One. Steel fabrication for the new portion is being done by Walters Inc. of Hamilton.
