Canadian Tire review: Automotive service department

I called Canadian tire here in Shawnessy to ask about tire change price. They told me $ 34.00. I thought that was great. I even took the flat tire and rim off the Mercedes. I took the new tire and rim with the flat to the service department. A couple hours later I picked up the rim with the new tire mounted. Now, the price is like $ 54.00 and the service guy is kind of rude. Told them I was quoted $ 34.00. They are not budging at first on the price. Then my wife started in on them, they dropped $ 10 off. I now find that the grease monkey has no idea about how to change a tire. My expensive Mercedes rim has damage to it. It looks like hell. You can see where he use the bar and and then chipped it real good. Absolutely, would never use these guys again. Its funny, the name says Canadian Tire... and they have no clue on how to change a tire on to a rim without damaging the rim.
