Ontario is massive both in area and in population, with 50+ square miles of territory and 160,000+ residents. It is a part of the greater Inland Empire
region, and more specifically, southwest San Bernardino County. Ontario borders Rancho Cucamonga
, Fontana, Pomona, Chino, and several other smaller municipalities. One of Ontario's most defining features is its airport, which serves as a major cargo hub for the southwestern United States and employs nearly 8,000 residents.
Like much of the rest of the Inland Empire, Ontario is within a few miles of mountainous terrain, specifically Mt. Baldy and its friends in the San Gabriel range. This proximity lends the city a striking vista; moreover, residents can ski, snowboard, camp, hike, climb, etc. with relative convenience. Those who work in the Riverside or San Gabriel Valley
areas might reasonably consider Ontario a viable hometown from which to commute, but those who work in Los Angeles will find that traffic and distance combine to render more-than-occasional trips to that area prohibitively time-consuming. Major arteries: the 60, 15, and 10 freeways.
