The National Airports Policy is a program of the Government of Canada involving the privatization or private operation of nearly all of the country's airports that was commenced during the 1990s. The policy continues to be controversial in Canada because of greatly increased airport fees that have resulted and the ongoing inability of airports to meet infrastructure requirements. For example, the fees charged to carriers and general aviation by the Greater Toronto Airports Authority at Toronto Pearson International Airport are among the highest in the world.
