Overall, Ontario grades C for safety (#215 of 416 graded towns in California, and #110 of 325 U.S. cities over 100,000): more crime per resident than 73% of U.S. towns, on crimes its police reported to the FBI in 2023–2025.
Crimes reported to the FBI per 1,000 residents a year, 2023–2025. “Rest of CA” is every other California city and town in the FBI’s tables; the U.S. figure is the FBI’s national estimate as published, averaged over the three years. The FBI publishes no national homicide or robbery rate in our data, so those compare with all U.S. cities and towns in its tables.
What stands out about safety in Ontario
2 of the 4 graded towns next door report less crime
Of the 5 California towns on Ontario’s borders, 4 have a Safety Grade: Eastvale (B−), Fontana (C+), Upland (C), Chino (C−). Rancho Cucamonga reported to the FBI for 2024 and 2025 but not 2023. Neighbors ↓
Among California towns, closer to the middle
California’s cities and towns report more crime than most states’, so Ontario’s place among its own towns differs from its national one: it reports less crime than 48% of the 416 California towns we grade, against 27% nationally. Safety Grade ↓
Homicides: below U.S. cities overall
Ontario’s police reported 5 homicides to the FBI in 2025. Over 2023–2025 that is 2.2 per 100,000 residents a year, below the rest of California (4.2) and below all U.S. cities and towns in the FBI’s tables (5.7). Violent crime ↓
Robberies: below the rest of California
72.3 robberies per 100,000 residents a year over 2023–2025 (100 reported in 2025), below the rest of California (123) and about the same as all U.S. cities and towns in the FBI’s tables (79.4). Violent crime ↓

Among the 325 U.S. cities over 100,000 we grade, Ontario reports less crime per resident than 66% (#110). Places like it ↓
A job center
Ontario has 125,911 jobs based in town for 187,013 residents (Census LEHD), so some reports involve people who work or shop there rather than residents. How to read it ↓
Reported crime is falling
Crime reported per resident fell from 2023 to 2025 by more than ordinary year-to-year swings, on the grade’s own score. Trend ↓

What’s behind Ontario’s grade
Property crimes plus four times violent crimes reported to the FBI per resident, 2023–2025, on a national curve. Both violent and property crime are higher than in most U.S. towns; violent crime is the closer of the two to typical. Its violent rate (2.8) is below the FBI’s national estimate (3.6) but higher than in most individual towns: the national figure is weighted by people, and the grade counts towns.
Reported crime is falling
Reported crime per resident fell from 2023 to 2025, by more than ordinary year-to-year swings. Per 1,000 residents, 2022–2025, against the rest of California.

99 people died in crashes on Ontario’s roads in 2019–2023
Ontario had 94 fatal crashes in five years, in which 99 people died; 24 were pedestrians and 7 were cyclists. 31 died in crashes on an Interstate.
That is 11.0 deaths per 100,000 residents a year, above the median for California towns of 100,000+ people (7.7, 76 towns).
Deaths are counted where the crash happened, not where the people lived: a highway through town adds through-traffic deaths, and residents’ own risk on roads elsewhere isn’t here. Town rates sit below state and U.S. rates because a third of fatal crashes happen outside any town. Road safety is described here and is not part of the Safety Grade.

What this data can and can’t tell you
- It’s reported crime. Only incidents reported to and recorded by police appear here. Many crimes are never reported to police.
- One number for all of Ontario. A citywide rate doesn’t show where incidents happen, and that can differ a lot from one part of the city to another.
- Visitors count too. Incidents involving people who work, shop or visit are counted against Ontario’s residents, which raises the per-resident rate.
- Whose population. Rates use the FBI’s population for the department (187,756 in 2025); our figure for Ontario is 187,013 (2025 Census estimate).
- Gaps are real gaps. A missing year means the department didn’t report a full year, not that nothing happened.
