1. Ignoring the Fine Print: Ottawa Rental Car Terms and Conditions
One of the biggest car rental mistakes Ottawa renters make is skipping the fine print. Many drivers rush through the rental agreement without reading the details about insurance, fuel policy, mileage limits, and deposit conditions.
According to a 2024 survey by AutoRentWatch, over 62% of renters in Canada admitted they didn’t fully understand their rental terms leading to surprise charges later.
Why It Matters:
- Some contracts include penalties for early returns or late drop-offs.
- Mileage limits can result in steep per-kilometer fees.
- Ignoring rental car deposit issues in Ottawa may freeze a significant portion of your credit card limit.
Tip: Always review Ottawa rental car terms and conditions carefully, and clarify anything unclear before signing.

Failing to check the car before driving away is another critical mistake. Many renters forget to document existing scratches, dents, or damage and later get blamed for them.

Tip: Always confirm the fuel policy type before accepting the keys, and take a quick photo of the fuel gauge before leaving.
3. Forgetting About Hidden Fees and Costs

A 2023 report by Canadian Travel Insights found that hidden charges add an average of 18% to total rental costs.
