Dynamex Canada Recognized By Transportation Health and Safety Association of Ontario.

DALLAS & ONTARIO, Canada -- Dynamex Canada, a subsidiary of Dynamex Inc. (AMEX:DDN), a leading provider of same-day transportation and logistics services in the United States and Canada, has been named a 2003 Achievement Award Winner by the Transportation Health and Safety Association of Ontario (THSAO). THSAO's Achievement Award is given to member firms, which have operated with a frequency and cost rate factor below the group average each year for three consecutive years. Dynamex Canada was a 2003 Achievement Award Winner in THSAO's Category 4, which requires one million person hours worked and winners must be 10 percent below rate group in accident frequency and cost rate. This is the second time Dynamex Canada has been recognized by THSAO.

"We are very pleased to receive this award. It was made possible by the outstanding work of our employees and business center managers in Ontario through outstanding team work to achieve such a great safety record," said Jim Aitken, president of Dynamex Canada. "This award is also significant due to the fact that companies do not apply for this award and Dynamex Canada was only one of three winners out of all the companies in our category. Winners are determined by THSAO based on stringent criteria. I want to congratulate all of our employees for their hard work and dedication which made this award possible."
