Ontario   

California is the most populous state of the United States. Located on the Pacific coast of North America, it is bordered by Oregon, Nevada, Arizona and Mexico. California is known for its pleasant climate and ethnically diverse population. The name California is most commonly believed derived from a storied paradise peopled by black Amazons and ruled by Queen Califia.

Ontario is a city located in San Bernardino County, California. As of the 2000 census, the city had a total population of 158,007 inhabitants. It is also the former home of the Ontario Motor Speedway. It takes its name from the Ontario Model Colony development established in 1882 by Canadian engineers George Chaffey and William Chaffey, who named the settlement after their home province of Ontario, Canada.

The area that is now Ontario was probably part of the lands used for hunting and foraging by the nomadic Tongva Indians, who were known to roam as far east as the western San Bernardino Mountains. The Serrano Indians may have also used the land the remains of a Serrano village were discovered in the neighboring foothills of the present-day city of Claremont.
