Well, with so much data available in the recent
releases of crime data from statistics Canada, another crime post is
definitely in order especially as a way to mark the end of the civic holiday long weekend. This time, a focus
on Thunder Bay and Greater Sudbury with respect to trends over time given they
are northern Ontario’s two largest metropolitan centers, along with a
comparison to Ontario as a whole to put things in perspective. Figure 1a presents the 2025 rates for both all-criminal
code incidents (excluding traffic violations) as well as the violent crime rate
for Thunder Bay, Greater Sudbury, and Ontario.
As Figure 1a shows, Thunder Bay is definitely experiencing higher police
reported crime rates than either Greater Sudbury or Ontario as a whole.

In 2025, Thunder Bay’s crime rate was 8,374 crimes per
100,000 population compared to 4,706 per 100,000 for Greater Sudbury and 4,297
per 100,000 for Ontario. Thunder Bay’s
crime rate in 2025 was 95 percent greater than Ontario and 10 percent more than
Greater Sudbury. In terms of violent
crime, Thunder Bay’s rate was 2,249 per 100,000 compared to 1,177 for Greater Sudbury
and 1,078 for Ontario. Violent crime in Thunder Bay in 2025 was109 percent
greater than the Ontario rate whereas Greater Sudbury was 9 percent
more.
As well, Figure 1b shows the homicide rate in Thunder Bay
for 2025 was 6.1 per 100,000 while in Sudbury it was 4.1 per 100,000 and only
1.3 per 100,000 in Ontario as a whole.
Needless to say, crime rates in Thunder Bay and Sudbury are above the
rates for Ontario as a whole but Thunder Bay in general is double the Ontario
rate while Sudbury is only about 10 percent more. However, in terms of homicides, both cities were
well above the Ontario rate in 2025 with Thunder Bay 369 percent greater than Ontario
as a whole and Sudbury 215 percent greater.
Figure 2 presents a dual scale chart for Ontario with total
crimes and violent crimes per 100,000 on the left vertical axis and the homicide
rate per 100,000 on the right. Observations for the three series are plotted
from 1998 to 2025 with a linear trend fitted to each series. If one looks at the three raw series, crime
rates including violent crimes and homicides generally declined from 1998 to
about 2014 and then started to rise.
Over that period, the crime rate in Ontario went from 7,019 per 100,000
to 3,549 per 100,000 while the violent crime rate declined from 1,222 to
789. Homicides also fell from 1.4 to 1.2
per 100,000. However, since then, all have increased with the crime rate in
2025 reaching 4,297 per 100,000, violent crime reaching 1,078 and the homicide rate
up to 1.3 per 100,000. In terms of an overall
trend, violent crime and total crime rates over the 1998 to 2025 period still
trend downwards but the homicide rate in Ontario now shows a rising long-term
trend.

Figures 3 and 4 present parallel charts for Thunder Bay and
Greater Sudbury. Both cities follow
patterns similar to the rest of the province in that overall crime and violent
crime rates decline from 1998 to 2014 and then start to rise with the overall
linear trend being downward for the overall 1998 to 2025 period. Both also show noticeable rising homicide rates
over the long term and declining overall crime rates when a linear trend is
fitted to the 1998 to 2025 data. In the case of violent crime over the 1998 to
2025 period, Thunder Bay shows a declining violent crime rate when the linear
trend is fitted while Greater Sudbury shows a gently rising violent crime rate
trend.


Nevertheless, crime is a matter of both level and trend when
making comparisons so Figures 5 and 6 focus on the two most serious categories –violent
crimes and homicides – to compare Thunder Bay, Greater Sudbury, and Ontario more
directly. Figure 5 presents the violent
crime rates and shows that Thunder Bay and Ontario do indeed trend down while
Greater Sudbury trends up over the 1998 to 2025 period. However, when one looks at the gap between
Thunder Bay, Sudbury and Ontario, based on the trends, it will be the end of
the 21st century when Thunder Bay matches Sudbury’s violent crime rate while it
looks like it will always be double the Ontario rate.


Things look somewhat worse when it comes to the homicide
rate (see figure 6). Both Thunder Bay
and Greater Sudbury have seen a major spike in their homicide rates since 2020
which has pulled their trend lines upwards.
However, Thunder Bay is definitely in a class of its own with a level of
homicides as well as an upward trajectory that makes the homicide rates in
Greater Sudbury and Ontario look modest by comparison. However, it was not always so. Up until 2008,
while homicide rates in both Greater Sudbury and Thunder Bay fluctuated around
the Ontario numbers, they tended to parallel each other. Indeed, for the 1998
to 2008 period, the average annual homicide rate (per 100,000 population) in
Thunder Bay was 1.4, Greater Sudbury 1.4, and for Ontario it was 1.5. For the 2015 to 2025 period, the average homicide
rate in Thunder Bay was 6.1 while for Greater Sudbury it was 2.2 and for
Ontario 1.6.
Taken over the long run, Thunder Bay has always had
generally higher crime rates than Ontario as a whole and the gap has been
fairly consistent. However, its reputation
as Ontario’s “murder city” is a relatively recent phenomenon. Thunder Bay’s average
homicide rates were not out of line with the rest of the province prior to 2008
and it has only been since then that homicide rates in Thunder Bay have soared.
It is indeed an interesting question as to what factors are responsible for the
increase since 2008. What is it about
the post 2008 period that makes that year in Thunder Bay such a break with the
past when it comes to homicides? Sudbury has seen a similar type of spike in homicide
rates since 2015 though it remains to be seen if that new upward trend will
continue. Given that this is a municipal
election year in Ontario, these numbers should be an interesting focus for debate.
