[5] Detroit is easily accessible to Tecumseh residents by the Ambassador Bridge or the Detroit–Windsor Tunnel, both of which are located within the neighbouring municipality of Windsor.

The town is named after Tecumseh, an 18th-century Shawnee chief and warrior who promoted resistance to the expansion of the United States onto Native American lands.

Land Grants to Charles Lesperance in 1796 from the British Administrators of the District of Hess is Tecumseh’s start.

County residents took horse and buggy into Tecumseh and then transferred onto the train, journeying by rail the rest of the way into Windsor.

The French were the original settlers of Tecumseh, the majority of them descendants of the Frenchmen who had lived in the area before the arrival of British administrators after the Paris Peace Agreement in 1763.

Today the street names from Ouellette Avenue in Windsor to Lesperance Road in Tecumseh are a reminder of the men that cleared the land and farmed it.

In 1921 it was felt that Tecumseh was not getting its fair share of improvements in proportion to the taxes paid to the municipality of Sandwich East.

A group of people headed by Malcolm Clapp petitioned the legislature to separate from the township and incorporate as the Town of Tecumseh with a population of 978.

The real growth in Tecumseh occurred in 1931 with the establishment of the Green Giant Factory as Fine Foods of Canada.

Now considered to be a bedroom community of Windsor, Tecumseh is often cited as an example of urban sprawl; new subdivisions have developed on some of Canada's most valuable agricultural land beginning in the late 1980s.

[9] The official results for the municipal election were signed off by Laura Moy, Director of Corporate Services/Clerk for the Town of Tecumseh.

Tecumseh is home to the St. Clair Green Giants of the Great Lakes Summer Collegiate League and play at Lacasse Park.
