Leamington was incorporated as a village in 1876. The community was named after Royal Leamington Spa in England, after having originally been called "Gainesville". It was a crossroads hamlet with about 300 residents and was known for its lumber products rather than its tomatoes. There were several docks, and fish were plentiful in Lake Erie, so much so that sturgeon could be speared from the shore and fish was the cheapest food available. Leamington once had many tobacco farms but now they are virtually nonexistent. In 1908 the H. J. Heinz company came to Leamington, bringing many jobs to the area and contributing to Leamington's growth.
According to the Canada 2011 Census there were 28,403 people living in Leamington. The Leamington Census agglomeration (metro area) includes Kingsville. Leamington is the most populous city on the Canadian side of Lake Erie, with a slightly larger population than both Fort Erie and Port Colborne.
