What our clients say

  • Had an overall great experience with QDFC and staff. As a business owner myself it was great to have such a wonderful customer experience as I did at QDFC. I would recommend them to anyone who asks. Thanks again Cheryl for your attitude and commitment to exceptional customer service that I received.

    Southern Ontario Dealer, customer since 2012
  • I had a customer picking up a car on Friday who had purchase finance from a well known Bank, QDFC helped me get what I needed quickly so I could deliver the car by dinner time. I never feel like I am dealing with my lender, QDFC is a real partner who wants to get the deal done.

    GTA Dealer, 10 years experience
  • My experience with QDFC has always been great. We have financed many vehicles from QDFC and dealt with Bryan and Wayne on all of them, they know the business and the they know the used car market, they are simply a cut above the rest. They are what every finance company should strive to be, and we would not deal with anyone else.
