Which is the Best Time to visit Ontario?

For the best mix of good weather and cheap tickets, book your trip between late January and early May. This window usually offers the most consistent cheap airfare to Ontario, along with fewer tourists and lower hotel rates. Temperatures range from the mid 60s to low 80s—perfect for walking, hiking, and sightseeing.

Avoid mid-June to August if you’re sensitive to heat. Summer highs often hit the upper 90s, and flight prices also rise due to vacation demand. Still, if you don’t mind the warmth and want to attend summer festivals, it’s doable—just book early.

Fall, especially September and October, is a great shoulder season. Weather cools down, and it’s still dry and pleasant. You’ll also find lower airfare and hotel deals post-Labor Day. If you’re coming in winter, December can get busy around the holidays, but early January is quiet and full of last-minute bargains.

So if your goal is to fly to Ontario on a budget, target spring or fall for the best deals and the most comfortable sightseeing weather.
