After I had signed my contract, I learned that the unlimited mileage only applies if you stay in the province of Ontario.  I had to go to Montreal and they charge $0.20 for every mile above 200 km per day.  This ended up doubling what I would have paid.

That was rip off number one.

I made the mistake of driving on the toll road.  I was expecting toll booths.  I'm not from the area.  But the system uses photographs of the license plate.  The bill of $5.75 (for 8.2 km of travel) was sent to the registered owner of the vehicle (Payless Car Rental).  They then add on $50 service!  And somehow they can't do math, so $5.75 + $50.00 = $62.25.  OK, I'm in the US, so maybe there is an exchange rate thing, except right now the US dollar is more valuable than the Canadian, so it should have been less than $57.75 not more.  

That's rip off number two.

On top of all this, they were quite rude.  When I first noticed the extra mileage charge and inquired about it, they said, "You should have read our website, it's there."  This was right after I had signed the contrat.  When I said, "cancel this", they said, "You've already signed a contract.  Minimum charge is one day."  Even then I would have been better off walking out of the door.  

How come these rating systems only have stars?  We need 5 raspberries!
