10 tips to save on your car rental in Ontario

1. Use filters to find the right car: Refine your search by selecting vehicle types and specific features. Whether you need a spacious SUV, a convertible for warm summer days, or a budget-friendly economy car, utilize the filters on Expedia to discover the ideal option for your journey.
2. Book in advance to help lower costs: Rental prices can vary with demand, so it's advisable to secure your vehicle well ahead of your travel date. By booking early, you’re more likely to lock in lower rates and enjoy a wider selection, especially during busy seasons.
3. Consider a smaller car for savings: Smaller vehicles are typically more affordable to rent and easier to maneuver in crowded areas. Mid-size options strike a good balance between cost, comfort, and fuel efficiency.
4. Age guidelines: Drivers under the age of 30 may encounter higher deposits or daily surcharges, and certain vehicle categories—such as SUVs or premium models—might not be available. This can also apply to renters over the age of 70. Always verify the age requirements before making a reservation.
5. Check fuel policies: Some rental agreements stipulate a full-to-full fuel policy, which means you must return the car with a full tank to avoid additional charges. This is often the most favorable option. Other policies may include full-to-empty or prepaid fueling options, which are acceptable as well, but be sure to return the car empty in that case.
6. Save on city and airport pickups: Picking up your rental car at airports often incurs a surcharge, but the convenience it offers may justify the extra cost.
7. Know your payment options: Most car rental companies only accept credit cards for payment.
8. Understand your insurance coverage: Car rental insurance can help you avoid unexpected expenses and provides peace of mind if something unforeseen occurs during your trip. Adding car rental insurance is a straightforward process when booking through Expedia.
9. Consider unlimited mileage: If you're planning extensive road trips, seek out rentals that offer unlimited mileage to prevent incurring extra charges.
10. Bring your driver's license and ID: A valid driver's license is necessary to rent a car.
