I don't mean to nit-pick, but 'petrol' and 'gasoline' are not generic terms for fuel. Some (piston-engined) propeller airplanes use petrol/gasoline, and are usually exempted from certain local taxes (as are marine users and farm users). Airliners are usually powered by turbine engines (often 'jets'), fueled by kerosene (or one of the JP-series fuels) which fall under their own tax regimes. *addendum: apparently Canada has implemented or is planning to implement a carbon tax on aviation fuel.
