Ontario, California is a dynamic Inland Empire city of approximately 185,000 residents situated at the foot of the San Gabriel Mountains in San Bernardino County. Founded in 1882 by Canadian brothers George and William Chaffey, Ontario was originally designed as a model agricultural colony with an innovative irrigation system that transformed the region into a thriving citrus empire. Today, Ontario has evolved into a major logistics and distribution hub, home to Ontario International Airport (ONT), one of Southern California's fastest-growing airports. The city sits at a geographic sweet spot — roughly 35 miles east of downtown Los Angeles — offering residents relative affordability compared to coastal communities while maintaining strong urban amenities. Ontario's grid-based downtown, anchored by Euclid Avenue's historic median parkway, reflects its carefully planned origins. The city blends working-class roots with growing suburban prosperity, featuring a robust restaurant scene, the Toyota Arena for major entertainment events, and proximity to mountain recreation at Mt. Baldy. Ontario's strategic position along the I-10 and I-15 freeway corridors makes it a logistics powerhouse, while its diverse, predominantly Latino community gives the city a warm, culturally rich character that distinguishes it from surrounding Inland Empire cities.
