Air Canada is preparing to expand its Vancouver, British Columbia, cargo terminal in preparation for receiving two 777 factory-built freighters from Boeing that will operate on trans-Pacific routes, said Jason Berry, vice president of cargo in a statement. The upgrade is part of a large program to improve cargo hubs across its network. Air Canada currently occupies a stand-alone facility that processes shipments moving on passenger aircraft at Vancouver International Airport. A tenant in an adjacent hangar is moving out and Air Canada will begin work in January on connecting and refurbishing the two buildings. “We’re in the early stages of just determining flow and process and how do you want it to look. It’s a big commitment for us,” Berry said.
