Agent: Jean Thibert
“If you don’t do any training, you will be obsolete in 8 years”.
Jean Thibert is a certified class A mechanic, with experience in the Ontario Department of Labour. He has an Inter-provincial Seal and an additional 8 years of experience as a Technical Consultant Specialist at a number of vehicle manufacturer head offices including Toyota, Mazda, Chrysler/Dodge and Suzuki. He is also a certified EEC IV & EEC V technician from Ford with an Advanced Engine Performance Diagnosis qualification for the 7.3 L DIT & 6.0 L DIT. Prior to some of this Ontario experience, he earned over 10 years of experience working in Alberta at a Ford dealership, focusing on Diesel engines.
Jean’s passion for repairs started early when he started helping his father repair and maintain his farm equipment. He made a decision to pursue being a technician and entered a trade school after hearing some wise words from his high school teacher who said: “If you don’t do any training, you will be obsolete in 8 years”. These words stuck with Jean and throughout the years he has continued to learn about new vehicle technology, taking evening Electronic Courses at Algonquin College in addition to the additional online courses and in class courses offered through his work experience as well as other all makes focuses, such as some specific gas and diesel engine diagnostic repairs for Chryslers.
