What are the additional charges in my Fare?
Fuel NAV Canada Insurance ATSC Airport Fees
Note: This information is intended as a guideline only for North American destinations. Actual fees, surcharges and taxes are subject to change and some exceptions apply.
Your fare may include NAV CANADA surcharges, Fuel surcharges and Insurance surcharges where applicable. Ticketable Airport Fees and the Air Travellers Security Tax (ATSC) are included in taxes component of your fare.
Fuel Surcharges: *NEW* For travel within Canada, Fuel Surcharge is now included in the base fare. For travel between Canada and the U.S., a fuel surcharge of CA$7.50 / US$4.65 per segment applies. In order to account for the recent surge in world oil prices, Air Canada, along with other Canadian and North American carriers have implemented a fuel surcharge.
NAV Canada: Nav surcharges within Canada are either $6 / $12 / or $17 based on distance. For transborder itineraries, $7.50 (CAD) $4.65 (USD) each way or $15.00 (CAD) or $9.30 (USD) per round-trip ticket. This surcharge is collected to cover the fees that Air Canada pays to NAV Canada to operate Canada's Air Navigation systems.
Insurance Surcharges: In order to account for the rising costs of aviation insurance, Air Canada along with other North American carriers have implemented an insurance surcharge. This insurance surcharge is $3.00 (CAD), each way for travel wholly within Canada. (Some exceptions apply).
Air Travellers Security Tax (ATSC): The Canadian Parliament has enacted an Air Travellers Security Charge (ATSC) to fund security personnel and security equipment in response to the events of September 11. For domestic itineraries, the ATSC tax is $7.00 (CAD) one way or $14.00 (CAD) return. For transborder itineraries, the ATSC tax is $12.00 (CAD) one way or $24.00 (CAD) return. For international itineraries, the ATSC tax is $24.00 (CAD) for each return or one-way trip.
Airport Fees: Many airports in Canada and around the world have implemented Airport Improvement Fees (AIF). Some Airports collect these fees at the airport at time of departure, other's are collected at the time of ticketing and are reflected in the taxes in your fare. Canadian Airports that include the AIF on your ticket are as follows: (All amounts CAD)

I also began the process of booking a fare from Chicago-O'Hare to Montréal-Trudeau to see what would be included:
Navcan and Surcharges 38.70
Canada Airport Improvement Fee 17.59
Canada Goods and Services Tax (GST/HST #10009-2287) 1.23
U.S.A Transportation Tax 71.16
U.S. Flight Segment Tax 12.40
U.S Passenger Facility Charge 4.50
Canada Quebec Sales Tax (QST #1000-043-172) 0.92
Canada Security Charge 7.65
September 11 Security Fee 2.50
U.S.A Immigration User Fee 7.00
Please note that most of these fees come from the United States, notably, the Transportation Tax. GST and QST are very small sums, and, i suspect are levied on the airport tax. I suspect the Navcan and Airport Improvement Fees are the costs to which you refer. These have always been included in the fare, whether i fly Air Doughnut, or an American carrier.
