Airport authority governance refers to how Canada's major airports are managed and who has decision-making power over them. In 1992, the federal government transferred operation of major airports to local, non-profit airport authorities (like the Greater Toronto Airports Authority or Vancouver Airport Authority) while retaining ownership of the land. These authorities operate independently but must follow federal regulations. Municipalities often want more influence over airport authorities because airports significantly impact local traffic, noise, land use, and economic development, yet cities typically have limited representation on airport boards. Debates about governance intensify when airports pursue expansions that municipalities oppose or when airport decisions seem disconnected from community concerns.
