Air North is flying both Ontario routes, YYZ and YOW, again, this year.

I have found that Avion points from RBC's fixed points travel program can be used with many Air North flights to reduce the cost. For example, 7500 Avion points will reduce the price of a oneway flight between BC and Whitehorse by CAD 175, a savings of $100. (If the naked "fare" price before fuel surcharge, airport and other fees and taxes is below CAD 175, your price reduction and savings will be lower.) For this option, you have to book with your Avion Visa card through the RBC portal.
