Canada’s private, user-fee-based ATC system–Nav Canada–believes that general aviation operators are double-charged for use of Canada’s aviation infrastructure and that fuel excise taxes should be reduced. In a recent letter sent to the minister of finance, Nav Canada president and CEO John Crichton noted that airline passenger taxes were eliminated after Nav Canada acquired Canada’s navigation services in 1999, and it is inequitable for general aviation operators to pay Canada’s fuel excise tax because the aviation infrastructure is supported via the user fees.
