This page lists cheap one-way fares leaving Ontario, not arrivals. Scan the table for date, duration, and stops, then open a destination if you want a two-month price calendar.

Fares from Ontario change as seats sell. Recheck the route before you buy, and if your metro has more than one airport, compare those boards as well.
