From 1911 to 1915, the Brockville Atlas Automobile Company of Canada produced Models D, E, F and G, ranging in price from $1800 to $2400 F.O.B. Brockville. For example, the Model D was a five or seven passenger car with 40 horsepower, right-hand drive, dual magneto, optional electric starter, headlights, sidelights, tail light, speedometer, license holder, mohair top with side curtains, electric horn, black with nickel trim and fine stripe, multiple disk clutch and leather upholstery stuffed with horsehair. By 1915, about 300 cars had been built, but supply shortages and economic problems created by World War I became unbearable for the young company.
The short-lived Atlas Automobile Company, like so many others, faced tough competition from the more reliable and lower priced Model T as well as Robert ‘Sam’ McLaughlin’s cars. In 1915 after only a few years of production, Atlas joined forces with Benjamin Briscoe, a car manufacturer based in Michigan, and re-organized as the Canadian Briscoe Motor Co., operating as a division of the Canadian Carriage Works building the Brockville Brisoce. In 1921 the Canadian Briscoe Motor Co. went bankrupt and the newly-appointed president, Clarence Earl of Willys-Overland, renamed the car the Earl and the company the Brockville Motor Car Company. Production continued in the United States for two more years, with the Brockville plant suppling parts for the Earl. Eventually, the Atlas Automobile Company, followed by both the Canadian Briscoe Motor Co. and the Brockville Motor Car Company, vanished into obscurity.
