On January 17, 2006, NAV CANADA announced plans for the construction of a new air traffic control tower at Buttonville Airport.

NAV CANADA is a privately run not-for-profit organization that operates Canada 's civil air navigation service (ANS and employs approximately 2000 air traffic controllers
The new tower, representing an investment of over $2 million, will replace the existing facility which was built in 1967 and is reaching the end of its useful life. Construction began in Fall 2006 and became fully operational on June 26, 2007.
The new tower provides expanded operational space, optimal visibility and the latest in air navigation equipment and technology for 12 air traffic controllers and two support staff who provide service to some 150,000 aircraft movements per year at Buttonville Airport. It is located on the south side of the airport – the opposite side of the old tower.
The new tower was designed and built using a modular design enabling the facility to be relocated in the future. New equipment and technology include the NAV CANADA Auxiliary Radar Display System and the Company’s state-of-the-art voice communications switch. Buttonville Airport is one of the busiest in the country, consistently ranking in the top 11 for air traffic volumes.
The new control tower's modular design is speculated to be because the airport's licence expires in 2010 and the Greater Toronto Airport Authority planning document for Pickering Airport assumes its closure by 2011 when GTAA funding of Buttonville (which replaced a Provincial subsidy) ceases. The Greater Toronto Airports Authority ( GTAA) operates Toronto Pearson International Airport in Mississauga Ontario, west of Toronto, Pickering Airport is a proposed international Airport for Pickering, Ontario, Canada, east of Toronto. 
However, Buttonville Airport is still privately owned and the GTAA has no jurisdiction to force its closure. As of yet, no plan to close the airport has ever been announced. Given the GTAA's reputation for charging high fees for using its facilities, it is possible that tenants of Buttonville will not want to move to a new Pickering airport.
