For the next two days, Air Canada will be having a seat sale on almost all flights within Canada. The sale will officially be ending on December 22nd at 11:59 p.m. EST, and you will have to book your travel dates for between January 4th and June 15th, 2016.
When you go to the deal site, you can browse through your city of departure to see what kind of one-way deals Air Canada has available for you. For instance, when I searched for flights leaving from Toronto to Ottawa on January 10th, I was able to find fares for as little as $122 (for a one-way fare).
