Biohazard and Pathogen Disinfection in Ontario, CA

Ontario began in 1882 as the Ontario Model Colony, founded by Canadian engineer George Chaffey and his brothers William and Charles, who named the settlement after their home province of Ontario, Canada.

Ontario was incorporated on December 10, 1891, and in 1903 it was proclaimed a "Model Irrigation Colony" by an Act of Congress.

Ontario has about 175,300 residents, according to the 2020 census, living in roughly 53,800 households that average about 3.3 people each.

The Chaffey brothers engineered an irrigation system that channeled water from the foothills of Mount Baldy down to the colony's farms, and citrus became the city's economic backbone; a Sunkist plant still operates in Ontario.

Euclid Avenue, the colony's main thoroughfare, is famous for its wide lanes and broad grassy median, and it was once served by a mule-drawn gravity railway in which the mules rode downhill on the cars.

Since 1958, life-size three-dimensional Nativity scenes have been displayed along the Euclid Avenue median every Christmas season.

Ontario International Airport is one of the busiest air-cargo airports in the United States, handling much of the freight that flows between the ports of Los Angeles and Long Beach and the rest of the country.

Ontario is home to Ontario Mills, a major outlet shopping mall, and was formerly home to the Ontario Motor Speedway.

The Chaffey brothers set aside half the colony's lots as an endowment for an agricultural college, and the college building's cornerstone was laid in 1883; education remains anchored by Chaffey High School in the historic core.

Ontario's 1927 Spanish Revival post office, designed by the first African American architect west of the Mississippi, has been converted into live-work artist lofts in the historic downtown.
