Ontario Overview


Ontario’s agricultural roots are still prevalent in the city, from its healthy share of farmland to the Historic Sunkist District around the former Sunkist Fruit Packing Distribution Center and famed, historic Graber Olive House. But like the rest of the Inland Empire, it’s growing and broadening at a rapid pace, in no small part due to its convenient location, 35 miles from downtown Los Angeles and with easy access to three interstates, two railroads and the country’s 15th busiest cargo airport, Ontario International Airport.

The service industry is a major part of Ontario’s economy, but warehousing and distribution have been big drivers too (Sam’s Club, Target and AutoZone centers are among the city’s major employers). Organizations hunting for the expanse of industrial space that can accommodate those businesses find far better luck in Ontario/the Inland area than in Orange County.

City leaders are expecting the city on the whole to follow that lead, doubling its population in the next two decades to more than 300,000 residents.
