Originally known as Ryegate Postal Station when it was first settled in 1792, Tecumseh was renamed in 1912 after the Shawnee tribe leader.  It was officially incorporated as a town in 1921.  Tecumseh had (and continues to have) a large French population.

In 1999 Tecumseh was merged with the Village of St. Clair Beach and the Township of Sandwich South into the Town of Tecumseh.  In 2033, the City of Windsor annexed approx. 23 square kilometers from the town.  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.

Every August, Tecumseh hosts the Tecumseh Corn Fest, a four day festival celebrating the town's agriculture.  The Corn fest draws people from all over the county and beyond.  The town holds concerts at the Festival and has hosted quite a few big-name entertainer's in the past.  Because of the City of Windsor strike, 2009 was also the inaugural year for Tecumseh's hosting of the Dragon Boat races in aid of the Cancer Society.  This event was so successful, it was decided to hold this event in Tecumseh in subsequent years.

To both its residents and visitors, Tecumseh offers a near perfect balance of small town qualities with big city amenities and opportunities.  With a population of 24,000 the Town is situated close to an international metropolitan population of five million and enjoys direct access to the NAFTA superhighway, yet small town service and friendliness prevail, enhanced by the warm climate and natural beauty of its southwestern Ontario location.

With successful industrial and business sectors, a commitment to sustainable, planned development and a wealth of cultural and recreational opportunities, Tecumseh offers a vibrant destination to visit or to call home.
