OFA GM Vehicle Discount

We know the GM O.F.A Program Inside and Out

  • Located in the heart of farm country we are extremely excited to be a part of the OFA vehicle discount program for all current members.
  • We know a thing or two about farming, trucks, and getting OFA members into new vehicles with some massive discounts while giving them top dollar for their trade-ins at the same time.
  • Our big selection of GMC Sierras and Chevrolet Silverados have brought in OFA members from not only the Alliston and surrounding area but also from all over Ontario.
  • Ontario Federation of Agriculture members have commented that dealing with Ernie Dean's has been very low pressure. Our staff is stacked with close to 100 years of combined GM Truck product experience.
  • We are here to answer your questions and provide you with all the information you need to make an educated decision.

What do I need to bring in to prove I'm an OFA member?

Simply call 1.800.668.3276 and the OFA will fax/email you a signed OFA - General Motors fleet program letter.

What if I don't see the vehicle I want on your website?
