What is the cheapest month to fly to Ontario?

In general, December is the cheapest month to fly from Thailand to Ontario. Due to it being the ‘off-season’ during this time, you can expect flight prices to be around $736. If you aren’t able to travel during the month of December, then book flights to Ontario from Thailand during August instead. Flights to Ontario in August, while not as cheap as those in December, still average around $799.

The cheapest day to depart on your flight to Ontario is on a Thursday when prices can be found for as low as $891.

When flying out on a Friday, the most expensive travel day of the week, you can expect to see flight prices from Thailand to Ontario for around $1,014.

What is the cheapest time of day to depart on your flight to Ontario?

In the morning is the cheapest time of day to fly from Thailand to Ontario when you can find flight prices for as low as $883.
