10 tips to save on your car rental in and around Ontario

1. Use filters to find the right car: Refine your search according to vehicle type and specific features. Whether you're looking for an SUV for added space, a convertible for summer drives, or an economy car for budget-friendly options, utilize the filters on Expedia to discover the perfect vehicle for your journey.
2. Book in advance to help lower costs: Rental rates can vary based on demand, so it's advisable to secure your car well ahead of your trip. By booking in advance, you're more likely to obtain lower rates and enjoy a wider selection, particularly during peak travel seasons.
3. Consider a smaller car for savings: Generally, smaller cars are more affordable to rent and easier to maneuver in crowded areas. Mid-size rentals strike a good balance between cost, comfort, and fuel efficiency.
4. Age guidelines: Drivers under 30 may encounter higher deposits or daily surcharges, and certain vehicle types—such as SUVs or premium models—might not be available. This can also apply to renters over 70 years old. Always verify the age restrictions before making a reservation.
5. Check fuel policies: Some rental companies require a full-to-full fuel policy, meaning you must return the car with a full tank to avoid additional charges. This is often the best option. Others may offer full-to-empty or prepaid fueling options, which can also be convenient. Just ensure you 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 added convenience may justify the extra cost.
7. Know your payment options: Most car rental companies primarily accept credit cards for payments.
8. Understand your insurance coverage: Car rental insurance can help you avoid unforeseen costs and provides peace of mind in case something unexpected occurs during your trip. Adding car rental insurance when booking through Expedia is simple.
9. Consider unlimited mileage: If you're planning lengthy road trips, look for rental options that offer unlimited mileage to prevent additional charges.
10. Bring your driver's license and ID: A valid driver's license is necessary to rent a car.
