Toronto Pearson International Airport starts a multibillion-dollar upgrade aimed at increasing passenger traffic. The project is designed to support growth in the airport’s number of travellers and improve airport infrastructure to handle higher volumes. According to reporting on the initiative, the airport’s goal is to raise its annual passenger numbers to more than one-third above current levels, reaching about 65 million passengers per year in the early 2030s. The upgrade is described as a major investment effort intended to expand capacity and support future demand for air travel in the Greater Toronto area. The airport frames the work as part of a longer-term plan to accommodate rising passenger traffic over the next several years while maintaining operational capacity during construction. Specific details about the scope, timing, and financing structure are not provided in the excerpts supplied. Overall, the sources agree that Pearson is launching the upgrade now with a stated target tied to passenger growth by the early 2030s.
