Philips ConnorThe most dangerous cities in Ontario are mostly those nearest to the US. However, that is just conjecture because there is no evidence of causation. Nevertheless, these cities face a lot of crime such as robberies, theft, house break-ins, and vandalism.
There is also the problem of drugs; a wide variety of drugs flood the streets, making it difficult to keep the youth away from crime. These are some of the places to avoid, or if visiting, to be on the alert.
Most Dangerous Cities In Ontario
1. Timmins
Timmins has one of the highest Crime Severity Index (CSI) scores in Ontario, driven by high rates of violent crimes, including assaults, drug offenses, and thefts. The city struggles with poverty, unemployment, and limited access to mental health and addiction resources, which fuels criminal activity. Isolated geography and under-resourced law enforcement agencies complicate response efforts.
Substance abuse, especially opioids, remains a persistent issue, with overdose-related crimes on the rise. Property crimes like break-ins and vandalism are also frequent, affecting residents’ sense of security. Combined, these factors contribute to Timmins’ reputation as Ontario’s most dangerous city.
2. Sault Ste. Marie
Sault Ste. Marie ranks high on Ontario’s CSI index, with violent crime, drug trafficking, and thefts being widespread issues. The city’s economy has been slow to recover from industrial decline, leaving many residents vulnerable to poverty and addiction. Gang activity and methamphetamine use have led to a spike in assaults and property crimes.
Limited social services and high unemployment contribute to recurring cycles of crime. The area also contends with youth crime and a rising number of domestic violence cases. Despite community efforts, Sault Ste. Marie continues to struggle with maintaining public safety and economic stability.
3. Thunder Bay
Thunder Bay consistently records some of the highest violent crime rates in Canada, particularly homicides and assaults. Deep-rooted issues like systemic racism, poverty, addiction, and inadequate access to healthcare plague the city. Indigenous residents, in particular, face disproportionate victimization. Drug-related crime, especially involving opioids and meth, is rampant.
Youth gangs and organized crime syndicates also contribute to the city’s dangers. Law enforcement has faced criticism for mismanagement and racial bias, further eroding community trust. Thunder Bay’s social challenges and its persistently high CSI score make it one of the most dangerous cities in Ontario.
4. Cornwall
Cornwall’s crime issues stem from a mix of economic hardship, drug addiction, and its proximity to smuggling corridors along the U.S. border. The city experiences high rates of property crime, particularly break-ins and vehicle thefts, alongside rising drug offenses and violent incidents. Cornwall’s small size belies its challenges: fentanyl abuse, trafficking, and related crimes are becoming more frequent.
The city’s economy, once reliant on manufacturing, has struggled, increasing unemployment and social instability. Limited policing resources and overstretched social programs further exacerbate these issues, making Cornwall one of Ontario’s top cities for crime severity.
5. Greater Sudbury
Greater Sudbury faces persistent issues with violent crime, drug addiction, and property offenses. The city’s Crime Severity Index has steadily increased due to a surge in assaults, domestic violence, and opioid-related incidents. Sudbury’s mining-based economy has seen ups and downs, contributing to social inequality and unemployment.
Break-ins, vandalism, and thefts are frequent, and the city’s public services struggle to keep pace with the rising demand for mental health and addiction support. Youth crime is also an emerging concern. These factors combine to make Sudbury a hotspot for crime in northern Ontario.
6. London
London, Ontario faces growing challenges with drug-related crimes, particularly due to a worsening opioid crisis. The city reports high levels of violent crime, including assaults and robberies, as well as a spike in property crimes like break-ins and car thefts. Certain neighborhoods, such as the Old East Village and downtown core, see frequent police activity.
Social inequality, homelessness, and mental health crises contribute to criminal behavior. Gang presence has also grown, escalating gun violence in some areas. Although London is a major urban center with many resources, its rising Crime Severity Index underscores ongoing safety concerns.
7. Windsor
Windsor, located at the U.S. border, struggles with drug trafficking, gang activity, and organized crime. Its position as a border city makes it a hotspot for smuggling and cross-border criminal operations. Violent incidents, including shootings and assaults, have increased in recent years. The opioid epidemic has hit Windsor hard, contributing to thefts and overdose-related crimes.

10. Guelph
Though often viewed as a quieter city, Guelph has seen a notable increase in property crime, including a high rate of break-ins and thefts.

Break-ins, theft, and assaults are common, particularly in neighborhoods with limited access to social services.

20. Sault Ste. Marie (Re-listed)
As previously noted, Sault Ste. Marie remains one of Ontario’s most dangerous cities due to ongoing issues with drug trafficking, gang activity, and violent crime. Economic struggles and limited mental health resources further exacerbate public safety problems.
