Grantham Township, Ontario
Grantham Township is a former incorporated and now geographic township on the Niagara Peninsula in Upper Canada, later Ontario.
In 1961, part of it was amalgamated into the city of St. Catharines. In 1970, the remaining portion was amalgamated into the new Town of Niagara-on-the-Lake.
Grantham Township was originally called Township No. 3, while surveying was first taking place from 1787 until 1789. Every lot in this new township was 100 acres in size, for a total of 230 lots. The Butler's Rangers and United Empire Loyalist were some of the first residents; with both groups receiving the land for free.
