Tax Grab
Couldn't agree more about the tax enviroment for aviation in Canada.
The Canadian Government used to pay for the system through the Ticket surcharge and fuel tax. Fuel tax was sort of fair as you pay more the more you burn. The more you burn means you probaly make more with that airplane.
When Canada privatised Nav Canada and airports etc. they continued to collect the fuel tax but it is put into general tax revenue to pay for other government programs. Then when improvements to the airports etc are needed (like security enhancements) they add more user fees.
It is going to cost the canadian aviation industry eventually as the skies open up and coompetition from elsewhere gets tougher.
