Eaton Hall is a large house in King City, Ontario, Canada, built in the Norman style for Lady Eaton in 1938–39 on a 700-acre (2.8 km²) parcel of land (partly the Ferguson farm). Lady Eaton and her husband, Sir John Craig Eaton acquired the land in 1920 and 1922 on recommendation from their friend Sir Henry Pellatt, who owned the nearby Mary Lake property. Lady Eaton moved into Eaton Hall three years after selling her city mansion, Ardwold. The house is adjacent to a body of water named Lake Jonda (a combination of the first three letters of her son John David Eaton's first and middle names), and nestled within the temperate forests of King Township. Upon completion, it contained 72 rooms. It became a beloved gathering place for the Eaton Family, owners of the Eaton's department stores based in Toronto.
Site plans and surveys for the property dating from 1921 to the 1930s all refer to its location being in Eversley, a community which no longer exists.
King's earliest settlement, Armitage, is now part of Newmarket. Its establishment was followed by those of Lloydtown and Kettleby. Subsequent settlements were founded near rivers, which provided the energy necessary to operate various mills.
The earliest were based in Laskay, Kinghorn, and Eversley. The hamlet of Springhill was established later and flourished; it was renamed King City, now the largest community in the township.
- Eversley is a hamlet that, although it has its own historical development, has slowly been subsumed into King City. It lies on King City's north-eastern edge, south of Snowball. It was also known as Tinline's Corners in the 1800s.
