Dominion Motors Ltd was a Canadian automobile manufacturer based in Walkerville, Ontario, which was established in 1910. The company initially planned to produce a vehicle modeled after the American Regal, which was to be named the Royal Windsor. However, upon its release in the summer of 1910, the vehicle was simply branded as Dominion.

The Dominion automobile featured a conventional design, equipped with a 35-horsepower four-cylinder engine and a tourer body style. It was priced at CDN $1,850, which positioned it within the mid-range market of its time. Despite its promising specifications, production numbers were limited, and the anticipated models for 1911 were never realized, leading to the company's eventual decline.
