I was travelling from JAPAN. I reserved an intermediate car through Automatit Travel(50981476) and the charge was said 136 $ for 4days. But while I arrived Payless off-site Toronto Airport office (very dirty) by their shuttle; I surprised they charging me 376$. By the by, I had to wait 40 mins for their shuttle after calling. Payless also charged airport Tax though they are off-site. They charged HST, Car license, Tyre depreciation (!), Insurance etc. I realized they are CHEATING but they said it's their terms & conditions. No way to back, they took 45 min to handover the car.
You may be cheat by hidden cost (4 times of reservation). On-line brokers will not told you total charges. AVIS, National, Herz- I used before was much better dealings.
Be careful to rent from Payless !!
