Crime is typically categorized into two main types: violent and property crimes. Violent crimes encompass offenses such as murder, rape, robbery, and assault, while property crimes include burglary, theft, and vehicle theft. Based on the most recent report, the Ontario crime rate is lower than the national average by 1.4%. Specifically, there were 503 violent crimes in Ontario, equivalent to 272 per 100,000 individuals, lower than the national average by 24.2%. Furthermore, Ontario recorded 3358 property crimes, amounting to 1817 per 100,000 residents, which was higher than the average by 3.3%.
The Ontario crime rate is about average when compared to all the other cities across the U.S. per 100,000 residents. When we compared the total crimes (violent and property) in Ontario, we found that the reported crime rates were almost equal to the average of all other areas that reported crime.
Ontario exhibits a property crime rate closely aligned with the national average. There were 1817 reported property crimes, which closely matches the national average of 1760 per 100,000 people. Consequently, the area's safety profile mirrors that of an average city, neither notably safer nor more dangerous than the norm. This balance suggests that Ontario maintains a consistent approach to property crime prevention in line with the broader national landscape.
With a total of 860 vehicle thefts last year, Ontario has one of the most stolen cars in the country at 465 per 100,000 people. This lands Ontario in the bottom 10% of all cities that reported crime and the chance of any vehicle being stolen is one in 215.
What is the prevailing sentiment among Ontario residents regarding the state of crime? A comprehensive survey conducted by AreaVibes, involving 85 respondents, sheds light on this matter. The results were as follows: 58% of Ontario residents expressed a notable sense of security, asserting that crime was virtually non-existent in their community, and they felt at ease strolling the streets after dark. While, 42% of those surveyed held a contrasting viewpoint, perceiving a higher incidence of crime, leading them to feel apprehensive about walking alone at night.
Before you decide to relocate, it’s always good to ask yourself “Is Ontario a safe place to live?” Although the answer might not be that simple, as some areas are safer than others, getting a good feel for the overall rate of crime can definitely be helpful. Overall, the Ontario crime rate is 1% lower than the national average. If we break that down daily, that translates into 10.58 crimes per day - 1.38 violent crimes and 9.2 property crimes.

Examining the change in crime rates from one year to the next provides valuable insights into the evolving safety landscape of Ontario, aiding residents in assessing whether it is becoming a safer or more dangerous place to live. These crime rates are categorized into two primary groups: violent and property crimes. Year-over-year, violent crime has decreased by 26.7%, while property crime has decreased by 15.9%. This comprehensive analysis offers potential residents essential information for making informed decisions about whether or not Ontario is a safe place to live.
The economic well-being of a city's residents plays a significant role in crime rates. High poverty rates and income inequality can lead to increased crime stats as individuals may resort to illegal activities to meet their basic needs. While lower rates could lead to a lower Ontario crime rate. The poverty level in Ontario is 13.3%, while the national average is 15.1%.
In Ontario, the current unemployment rate stands at 4.6%, diverging from the national average of 4.9%. The availability of job opportunities is a pivotal factor influencing unemployment and underemployment rates. Communities where individuals contend with limited employment prospects or a preponderance of low-wage positions may witness elevated rates of joblessness and income inadequacy, which can contribute to heightened crime levels driven by financial insecurity. Conversely, areas characterized by robust employment rates often experience a reduction in overall Ontario crime rates.
Escalating cost of living expenses, encompassing exorbitant housing costs, grocery and healthcare expenditures, can induce financial strain on individuals and families, particularly those with limited financial resources. Such economic stress may propel individuals towards criminal activities, including theft or burglary, as a means of addressing their financial hardships. Conversely, cities characterized by a lower cost of living may alleviate economic pressures, potentially resulting in a reduced crime rate. In Ontario, the cost of living is 44.66% higher than the national average, reflecting a more affordable economic environment that could contribute to a decrease in crime levels.
