Canada is widely regarded as a secure nation, with a relatively low crime rate compared to its southern neighbour, the United States. However, there are some cities in Canada that are considered unsafe and best avoided. Despite this, overall, Canada is a safe place to live in.

In Canada, the Crime Severity Index (CSI) is utilized to measure police-reported crime. This index provides values that accurately reflect the relative number and severity of crimes in various country regions. It is not simply a raw count of crimes, but rather a more nuanced and valuable severity-weighted statistic.

Over the past few years, there has been a stabilization in the nationwide CSI measure. This measure has changed from 73.9 in 2020 to 73.1 in 2021.

According to recent reports, the CSI in Canada has decreased by 7% from 2019 to 2020. This indicates that Canada, as a whole, has become a safer place. However, the decrease in crime rate is not uniform across all of its cities.

Let’s explore the top eight cities in Ontario that have been identified as the most dangerous, along with the twelve cities in other provinces across Canada that are also known for their high crime rates.

If you are planning to relocate to Canada or are considering visiting the country, it is important to be aware of certain areas that may not be the best option for you. By being informed, you can make a more informed decision and potentially avoid any potential issues.
