The city is home to the Ontario International Airport, which is the 15th-busiest airport in the United States by cargo carried. Ontario handles the mass of freight traffic between the ports of Los Angeles and Long Beach and the rest of the country.[8]

It takes its name from the Ontario Model Colony development established in 1882 by the Canadian engineer George Chaffey and his brothers William Chaffey and Charles Chaffey.[9] They named the settlement after their home province of Ontario.
