Brock Motors Ltd. (formerly Stansell Motors Ltd.), was founded by William Riley Stansell in 1921 in Amherstberg, Ontario, Canada. The factory had previously been home to Amherst cars. The company announced that it intended to build 10,000 vehicles per year. Before production started Stansell Motors was renamed as Brock Motors Ltd and only one car was ever produced, the Brock Six, a large five-passenger touring car. The company closed in 1921. Stansell moved to London Six cars in London, Ontario in 1921.
