This time we picked up the car in downtown Toronto and returned it at Toronto Pearson International Airport. Neither location could be directly found using either Tante Route or Google Maps. Luckily, we had found a guide from an online forum for the downtown location and picked up the car smoothly. However, when returning the car to Pearson Airport, Tante directed us to the departure area on the third floor of Terminal 3, which was especially problematic since the return address on the rental order couldn't be found on Google Maps. Ultimately, we paid 20 CAD to have an African driver lead us to the underground parking. We arrived at the airport at noon, but it wasn't until after 2 PM that we managed to return the car, resulting in a two-hour overtime fee. The root cause was that the return address was vertically below the third floor of Terminal 3, and the navigation maps couldn't recognize the exact return location. With our return flight shortly departing, the situation was very stressful. If rentalcar.com had clearly detailed the pick-up and return locations on the map within the order, this incident could have been avoided. Despite multiple rentals with rentalcar.com, this was the first embarrassing issue we encountered. rentalcar.com's service needs improvement.
