Grantham Township is a former incorporated and now geographic township on the Niagara Peninsula in Upper Canada, later Ontario.[1]
In 1961, part of it was amalgamated into the city of St. Catharines.[2] 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.[3]
