The establishment of the village dates back to the 1860s at the junction of the Mississippi Road, Frontenac Road and Snow Road colonization roads and it still retains its small-town Ontario charm. Originally called Buckshot, the name had to be changed when the Post Office Department objected to it. In 1877, an ultimatum was given to rename the village, or the Post Office Department would do so. After much debate by the village folk, the name "Plevna" was finally decided upon after one resident commented that all the debate over the selection of a new name reminded him of the situation that was ongoing at the Siege of Plevna, then part of the Ottoman Empire. The name was suggested to the Post Office, which adopted the name.
