How to find a cheap car hire deal in Ontario

  • Whether you need a compact for scooting around the city or bigger wheels for bigger plans, we'll help you find a cheap rental car in Ontario. Choose from options averaging $104 a day and hit the road for less.

  • Cruise off with savings by reserving your wheels in January. With average daily rates of $108, it's the cheapest month to rent a car in Ontario.

  • We've cracked the code on when to book. Three weeks in advance gives you better odds at securing a cheap rental car in Ontario.

  • Hertz, Fox - Rent A Car and Dollar are popular providers offering car hire deals in Ontario.

  • The coverage Hertz or another company offers for your Ontario car hire can vary, so be sure to check the fine print. While some include a collision damage waiver (CDW), others will apply a surcharge for it.

  • Look into booking a one-way rental. You might be able to score a good deal if the provider needs to relocate some of its vehicles. Find the best available rates for a car for rent in Ontario by selecting 'Return car to a different location.'

  • Save money on fuel by picking a car hire in Ontario that offers a 'Fair fuel policy.' You pick up the car with a full tank and return it full, so you're only paying for what you use.

  • Hit the road without watching the miles and racking up extra charges. Go to the 'Policies' filter and choose 'Unlimited mileage' to find a car that lets you roam without limits.

  • Jetting into Ontario? Consider picking up one of the car rentals in Ontario International Airport. That way, you can take off on your terms not long after you land.

Compare car hire types in Ontario

  • Small: These cheap rental cars in Ontario may be small in size, but they live up to big expectations. Including mini and economy vehicles, they're easy to drive, fuel efficient, and just the thing for short trips.

  • Medium: Choose from compact and intermediate cars that combine comfort, space and fuel efficiency. Easy to manoeuvre around cities and roomy enough for longer drives, they're a reliable fit for most trips.

  • Large: Long drives fly by in this Ontario car hire category. Also known as full-size, they've got the engine power for lengthy trips. The extra space and comfort make them an excellent option for families and groups of friends.

  • SUV: SUVs are adventure on four wheels. All-wheel drive and everyday versatility equip them for city streets and rugged backroads alike.

  • Van: If you're after a car for rent in Ontario that can handle a small crowd (and their luggage), a van is the roomy solution. Including commercial vans and trucks, they're best suited for group outings, business use or moving.

Insurance and optional extras

  • Excess insurance covers the fee you'd have to pay if your Ontario car hire is stolen or damaged. While not mandatory, you'll be glad to have it if something goes wrong. Just remember that policies differ from one provider to another, so make sure you understand exactly what's included.

  • From GPS units to mobile Wi-Fi hotspots, the right extras can seriously upgrade your ride. Look into which add-ons could improve your trip when you rent a car in Ontario.

Good to know

  • You usually have to be at least 21 years old to rent a vehicle in the United States. Being younger isn't always a deal-breaker — just be prepared for extra fees or rules. Check the suppliers' terms and conditions before you book.

  • Bringing the kids with you? Car seat regulations vary from one location to another, and the correct setup may depend on their age, height and weight. Check if you need to add one to your Ontario car hire reservation.

Hit the road: Where to drive from Ontario

  • Lock in a car hire deal in Ontario and then get ready to discover the city's most popular attractions, like Museum of History and Art, Ontario and Pacific Plaza. Whether you drive or get there another way, you'll want to see these highlights before you go anywhere else.

  • If you need a place to stay in Ontario while taking in the sights, consider Hotel Seville - Ontario Airport/Chino or Hotel d'Lins Ontario Airport.

  • Or collect your cheap car hire in Ontario and then set out for Long Beach. Around 56 kilometres south-west of Ontario, SkyThrills! - Fly a Real Fighter Aircraft & Become A Fighter Pilot For A Day! Long Beach, CA and Queen Mary are major attractions that make the drive more than worth it.

  • Unwind after a big day out in Long Beach at Hotel Maya - a DoubleTree by Hilton Hotel. Or spend your downtime at Hyatt Regency Long Beach.

  • Keep the momentum going and road-trip it to Chula Vista, around 161 kilometres south of Ontario. Make your first stop San Diego Aquatica, then follow it up with Chula Vista Bayfront Park.
