When is the cheapest time of year to fly from Calgary, AB to Toronto, AB?
The AB you are referring to means the province of Alberta. You are almost asking like when is the cheapest time of year to fly from Houston TX to Chicago TX which of course does not make sense. Toronto is in the province of Ontario. I would visit website such as travelocity.ca or exepedia.ca and see if they have any specials on. You can also check sunwing.ca for specials too.
