They then compound the problem with parasitic forms of taxation that usually flow straight out of the sector.”
To be fair I think Air Canada would agree with this statement. How many Torontonians cross the border to Buffalo because it is cheaper to fly from there. A flight out of Pearson has XYZ costs and taxes included to the point that people don't even want to fly from their own country.
Air Canada would probably like these "parasitic forms of taxation" lessened in order to compete better against the US carriers.
