Ontario is a city located in southwestern San Bernardino County, California, United States, 35 miles east of downtown Los Angeles. Located in the western part of the Inland Empire region, it lies just east of the Los Angeles county line and is part of the Greater Los Angeles Area.
In the years following Ontario’s founding, the economy was driven by its reputation as a health resort. Shortly thereafter, citrus farmers began taking advantage of the city’s rocky soil to plant lemon and orange groves. Agricultural opportunities also attracted vintners and olive growers. The Graber Olive House, which continues to produce olives, is a city historical landmark and one of the oldest institutions in Ontario. Dairy farming is also prevalent, as it continues to be in neighboring Chino.
Ontario has a franchise of The Dinner Detective, America’s Largest Interactive Murder Mystery Dinner Show. The Los Angeles and Denver franchises were voted as the “Best Dinner Show” in 2007, 2008, 2009, and 2010. Ontario is also the home to the second largest consumer Quilt Show in the United States, Road to California. The quilt show books over 2,400 room nights and has a recorded attendance of over 40,000 attendees.
