During the last Thunder Bay City Council Meeting, the
discussion over the city’s new Smart Growth Plan included a few remarks by the mayor
that the city was growing and that according to conversations that he has had,
it is probably around 150,000. Of
course, while it cannot be denied that Thunder Bay has seen its population grow
over the last few years based on even anecdotal observation, the 150,000 number
is vastly at odds with any estimate provided by Statistics Canada or even the
City itself in its annual submissions of municipal data to the Ontario Government
via the Financial
Information Return (FIR). This type of mixed messaging and confusion on
what Thunder Bay’s population is, including the usual casting of doubt on Statistics
Canada, does not do anyone any favours.
This becomes even more problematic given that Thunder Bay is engaged in
long-range financial planning that also presents population and household
numbers.
Thunder Bay will soon be dealing with a Long-Range Financial
Plan for the 2026 to 2035 period, and the current
draft presents population estimates (Plan starts at page 32 of December 9th
Agenda for Finance and Administration Standing Committee) taking the city from
112,330 in 2020 to 117,003 in 2025. Over the
same period, the same draft has the number of households in Thunder Bay growing
from 47,180 to 48,405. In other words, the
City of Thunder Bay says it has added 1,225 households since 2020 and 4,673 people. However, it should be noted that
average household size in Thunder Bay is approximately 2.2 people so the
additional households should probably only be associated with only an
additional 2,695 people. Or perhaps it
could be that our current population increase is also being accompanied by an
increase in household size. In addition,
the household number in the draft plan is also out of whack with the household
number and population in the finally submitted Thunder Bay FIR report to the
provincial government for 2024 which says Thunder Bay has 50,995 households and
a population of 108,843.
This range of estimates – none of which incidentally
approach 150,000 - begs the question as to what then the population of Thunder
Bay is? Part of the issue is that there
is a distinction between the population of Thunder Bay as contained within the
city limits – the City of Thunder Bay – and the population of the immediate
surrounding area as defined by Statistics Canada as the Census Metropolitan
Area (CMA). The accompanying map shows
that the city itself is contained with a much larger CMA which in turn is
within an even larger District which according to Statistics Canada in 2024 had
a population estimated at 157,293. Perhaps this the source of so much confusion
among our elected officials in that they conflate the population of the district
(which essentially stretches from Fort Frances to Wawa) with the population of
the city itself which is anywhere from 108,843 to 117,003 or perhaps even the
CMA at 133,063. That Thunder Bay is a
service centre for a regional population of 157,293 that accesses its
government, health, retail and education services is a reasonable statement but
saying that our city itself is swarming with 150,000 people is not.

The accompanying figure plots three population series: the
CMA and City populations from Statistics Canada and the City population
according to the annual FIR reports - which I again must note, are filed by the
City of Thunder with the provincial government.
For the CMA, the StatsCan numbers show a decline from 2001 to 2011 from
126,696 to 124,926 followed by a flat population that starts to increase after
2016 and in 2024 is estimated at 133,063.
For the city itself, the Statistics Canada numbers show a pattern like
the CMA but the numbers are larger than the numbers the city itself seems to be
using in its annual FIR reports. The
City of Thunder Bay’s population according to this series declines from,
113,298 in 2001 to 110,861 in 2016 and then starts to grow and in 2024 was
estimated at 117,100. According to the
StatsCan estimates, between 2016 and 2024, the Thunder Bay CMA grew 6.6 percent
and the city itself 5.6 percent.
However, the FIR numbers say the Thunder Bay had a population of 115,419
in 2001 which shrank to 107,909 in 2016 and has since grown an anemic 0.9
percent to 108,843.

If the city is making the case that its population numbers
are underestimates that affect the grants it receives from the federal and
provincial governments, a key part of the problem is that the city itself seems
to be submitting numbers in reports that are much lower than the StatsCan estimates. On the other hand, the provincial government
probably has a good handle on how many people live in the city of Thunder Bay
versus the surrounding area based on Driver’s License and OHIP usuage data and does believe
the population of the city itself is closer to 108,000 with a large percentage
of the CMA population outside the city. Indeed, based on the FIR estimate, 20
percent of the CMA population lives outside the city limits and is probably a
factor in all the traffic being generated as they come in and out of town
accessing city services.
Of course, rather than blame someone else, the solution here
in part is that the city of Thunder Bay needs to get its act together in terms
of getting a handle on its own numbers. For
a city with 3,207 employees (2,165 full time, 995 part time and 47 seasonal),
Thunder Bay seems unwilling or unable to hire a couple of graduate school level
trained economists and statisticians who could provide a more disciplined and
consistent approach to compiling and analyzing its economic and population data
to make its case with both higher tiers of government and its own municipal ratepayers. Instead, we are left with plans,
pronouncements and submissions that have conflicting data and population
estimates that seem to emerge out of thin air.
