Brouseville, Ontario is a small rural hamlet located approximately north of Cardinal. The central location of the hamlet is the intersection of Brouseville Road and County Road 22. Brouseville extends easterly to the township boundary, and Kain Road is considered to be the southern boundary of the community. Brouseville, formerly known as Bolton's Corners, was renamed in 1872 after Dr. William H. Brouse, a local travelling physician. Brouse took over the South Grenville seat in the 1872 federal election which prompted residents to change the name in his honour.
