Yume, yeah, I don't understand the strong currency either.
Whatnext, if YVR completely eliminated the AIF, fees somewhere else would have to go up (likely landing fees) due to the ground rent the airport authority pays every year to the federal government, which was over $65 million last year. It's a no-win as far as 'competitiveness' goes.
The AIF and federal ground rent payments to me are symbolic of a greater structural problem with Canadian transportation. The Air Canada CEO alluded to this in his presentation at the Annual General Meeting in May. Combine that with higher gax taxes than in the US, security charges (all of which of course is reinvested by the feds into security infrastructure, naturally...

)... well you get the picture. Someone on Airliners.net broke down the cost of a ticket on YYZ-YUL roundtrip ticket on AC a couple of years ago as follows:
YYZ-YUL sector (Q Class): CAD$109.00
YUL-YYZ sector (Q Class): CAD$179.00
Total Fare: CAD$288.00
Navcan and Surcharges: CAD$58.00
Canada Airport Improvement Fee: CAD$27.00
Canada Security Charge: CAD$13.08
Canada-Quebec Sales Tax: CAD$1.20
Canada Goods and Service Tax: CAD$27.03
Total Charges: CAD$126.31
Total Fare: CAD$414.31
Is it any wonder people go south to Seattle or Bellingham?
