In 1764 Prince Edward Island was divided into 67 lots by British surveyors. In 1767, these lots were awarded to British landlords. Lennox Island, 1320 acres, was given to Sir James Montgomery as part of adjacent Lot 12.

By the 1780’s the pressure of British Isles settlement on Prince Edward Island was beginning to have an impact on the traditional Mi’kmaq way of life. The routes that Island Mi’kmaq followed for millennia were being restricted by new farmland or by the farmers themselves. Many species of game were fast disappearing as the Acadian forest was being cut and burned. The expiration of many species was beginning to appear imminent.

Despite the fact that Malpeque Bay had been used by our forebears for thousands of years, no land here or anywhere else on Prince Edward Island was formally set aside by the colonial government for settlement by the Mi'kmaq. Nevertheless, Lennox Island continued to be a favourite campsite and a meeting place and disputes between Mi’kmaq and European settlers to neighbouring areas erupted over resources such as Lennox Island’s timber and salt-marsh hay.

The Aborigines Protection Society, a London-based organisation devoted to assisting Aboriginal Peoples, purchased Lennox Island in 1870 for £400 so that it might be set aside for the Mi’kmaq of the area. By the early 1870’s the nucleus of the present village was in place: a log chapel, a cemetery, several frame houses, barns and about 25 acres of cleared land.

In 1873 Prince Edward Island joined Confederation. After the passing of the 1876 Indian Act, Lennox Island was defined as a special reserve. In 1970 the federal government passed an order-in-council giving Lennox Island formal Indian Act reserve status.
