10 tips to save on your Ontario car hire

1. Use filters to find the right car: Refine your search by selecting vehicle type and desired features. Whether you need an SUV for ample space, a convertible for summer outings, or an economy car for budget-friendly travel, utilize the filters on Expedia to discover the ideal vehicle for your journey.
2. Book in advance to help lower costs: Rental prices can vary based on demand, so it’s wise to secure your reservation well ahead of your trip. By booking in advance, you're likely to obtain lower rates and better availability, particularly during peak seasons.
3. Consider a smaller car for savings: Smaller cars typically come at a lower rental price and are easier to maneuver and park in crowded areas. Mid-size vehicles strike a good balance among cost, comfort, and fuel efficiency.
4. Age guidelines: Drivers under the age of 30 may encounter higher deposits or daily fees, and some vehicle types—such as SUVs or luxury 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 agreements require a full-to-full fuel policy, which means you must return the car with a full tank to avoid additional charges. This option is typically the most economical. Other policies may include full-to-empty or prepaid fueling options, which are acceptable as well, but ensure you return the vehicle empty in those cases.
6. Save on city and airport pickups: Picking up your rental car at the airport often incurs a surcharge, but the convenience it offers might make it worthwhile.
7. Know your payment options: Many 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 in case something unforeseen occurs during your trip. Adding car rental insurance is simple when booking through Expedia.
9. Consider unlimited mileage: If you’re planning extensive road trips, seek out rental options 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 vehicle.
