Windsor has been a base of American automobile companies from the beginning of the 20th century and it remains a major center of auto industry employment and manufacturing. Other major employers in the city include the H. J. Heinz Company, which processes farm products from the agriculturally rich land outside of the city, and Hiram Walker and Sons Limited, makers of Canadian Club whisky. The most significant new stimulant to the local economy is Casino Windsor, which opened in 1994 and moved to its permanent home in 1998. The casino has also increased tourist traffic to Windsor. A 2006 real estate survey has estimated the population of Windsor, Ontario at 216,473.
