TORONTO, ON -- David Bradley will be stepping aside as president and CEO of the Canadian Trucking Alliance and the Ontario Trucking Association at the end of 2017. The announcement, which came Friday from both organizations, gave no reason for his upcoming departure. In a recent letter to OTA Chairman Scott Tilley, Bradley said, "It is with some amazement, but always with appreciation, that I think back on what a leap of faith it was back in 1991 to have entrusted such a young guy to represent such an incredible and important industry." In a letter to CTA chairman Mark Seymour, Bradley expressed similar sentiments. Bradley joined OTA as director of economics in 1985 after starting his career on Bay St. Six years later, at the age of 33, he was promoted to president of the OTA.
