History & History Related Items

Ontario history:

The City of Ontario, California was founded in 1882 by the Chaffey Brothers, George and William of Ontario, Canada. The brothers moved from their native homeland and settled in the region to establish a "Model Colony" for others migrating to the valley. They installed all basic improvements including laying out streets and the creation of a mutual water company. They even established the first commercially successful hydroelectric plant in the United States. All this to attract people to come and live in their planned colony. Their methods became enormously successful and soon settlers began the process that would transform Ontario into a prosperous community. By 1887, the railroad came to Ontario, furthering its growth as both an industrial and a residential community.

Today, Ontario has become the fastest-growing business and industrial area in the Inland Empire. Ontario encompasses approximately 40 square miles and has a city population of over 138,000. Convenient Ontario International Airport is located here with record-breaking annual passenger traffic.

Downtown Ontario is the historical focus of this rapidly changing city. The unique beauty of its tree-lined main thoroughfare, Euclid Avenue, has become a landmark for area residents and visitors. There was a time when mule cars carried passengers up and down the center median, now hundreds of vehicles travel Euclid each day. The downtown area is comprised of approximately four hundred individual businesses.
