Frequently asked questions about Ontario
Common traveler questions answered
What are the top things to do in Ontario?
Ontario offers world-class attractions, guided tours, restaurants, nightlife, shopping districts and live events. Explore the rails above for ranked attractions, food & drink picks, shows and experiences happening in the next 90 days.
How many days do I need in Ontario?
Most travelers find 3-5 days is enough to see the main attractions in Ontario, with extra time for day trips or beach time. Long weekends (3 days) work for highlight tours; a full week lets you slow down and explore neighborhoods, cuisine and nearby destinations.
What's the best way to get around Ontario?
Public transport, walking, taxis and rideshares cover most central areas. Renting a car gives you the most flexibility for day trips, beaches, and destinations outside the city center, with all major suppliers available at Ontario International Airport (ONT).
When is the best time to visit Ontario?
Shoulder seasons (spring and autumn) typically offer the best balance of weather, crowds, and prices. Summer brings peak attractions and events but also the highest hotel rates and longest queues. Check current event listings above to align your visit with festivals or shows that interest you.
Where is the best area to stay in Ontario?
Central neighborhoods near top attractions are convenient for first-time visitors. Compare hotel rates from hundreds of sites using the KAYAK link in the sidebar to find the right balance of price, location, and amenities for your trip.
Do I need a car in Ontario?
It depends on your itinerary. For city-focused trips with central hotels, public transport and rideshares often work fine. If you plan beach days, day trips, or visits to suburbs and surrounding areas, a rental car is usually faster and cheaper than booking individual transfers.
