Gray-Dort's originated in the Chatham carriage works of William Gray & Sons Company Ltd, founded in 1855 by William Gray.
In the mid 1900's Robert Gray (William's Father, then president of the company) began to build Ford bodies for the Walkerville Factory. They continued to do so until 1912. During this period, they also built bodies for the locally built Chatham car.
In 1915 Robert Gray obtained the Canadian rights to manufacture the Dort Automobile from Flint automobile manufacturer J. Dallas Dort, of the Dort Motor Co., and that year Gray-Dort was formed. They produced two cars the first year, a Model 4 roadster, and a Model 5 touring car.
Over the years Gray-Dort became known for their cars of reliable quality--ones that easily started in all weather conditions.
In 1923, after several years of successful but stressful business, J. Dallas Dort decided he wanted out of the automobile business. Try as he might, Robert Gray could not dissuade him. A few months later, Dallas Dort died while playing golf. Their easy access to U.S. sources of engineering and mechanical parts having abruptly come to a close, the company began to lose money. Gray-Dort scrambled to find new a U.S. based partner to no avail, and the last few years of its life were spent liquidating assets.
Over the course of it's lifetime, Gray-Dort manufactured around 26,000 quality automobiles.
