Thunder Bay is in Ontario, and the climate zone on this page is 7A. The moisture letter on this zone is humid (7A). The note reads: Zone 7A of the National Energy Code of Canada for Buildings (zones 4 to 8, from mildest to coldest). On the IECC scale used on our state pages, the number rises as the climate gets colder, from 1 (hot) to 8 (subarctic). Source on this page: National Energy Code of Canada for Buildings (2020) building climate zones by heating degree days, as published by ClimateData.ca, as of 2020. Zone is a reason to lead with the jobs people in this climate ask about, not a rank factor by itself.
Read as a set, the sourced lines suggest what a Thunder Bay contractor should say first. Heating is the larger degree-day number, so cold-weather comfort is the first story for Thunder Bay. Check it against the grid. A message can be right for the climate and still be invisible three miles from the shop.
Dwelling type in Thunder Bay shows 65% single-detached. That is higher than the national figure of 53% in the same note. The note on that line says: National: 53% (share of private households). Use the number to choose the audience. Do not treat it as the share of your revenue.
Heating (5,683) is larger than cooling (77). The heating degree-day value is 5,683 and the cooling value is 77. Both figures use base 18 C. The heating note says the reading was measured at FLINT (about 32 km away). Pages and ads can lead with cold rooms, drafts, and heating bills. Put the larger load first on the Google Business Profile services and on the main service pages.
Thunder Bay's median home value on this page is $300,000. That is lower than the national figure of $472,000 in the same note. Source on this page: Statistics Canada, 2021 Census of Population, table 98-10-0257-01 (value of dwelling by structural type), as of May 11, 2021. The note states the values are in Canadian dollars. Do not invent a typical job size from this number. Job price depends on the scope the contractor actually sells.
Owner-occupied homes in Thunder Bay are 68%. That is higher than the national figure of 66% in the same note. The city figure is at least half, so owner-occupiers are the larger group in this survey line. They are usually the people who can commission insulation on a house they live in. The note on that line says: National: 66% (share of private households). Aim the website and the map listing at people who can approve the work.
108,843 is the population figure for Thunder Bay. The note on that line says: 2021 Census count, up 0.9% from 2016. The province line reads Ontario. Rankings on Google Maps are local to the searcher, so a strong pin near the shop can still leave the rest of a city this size uncovered.

What this means for your marketing in Thunder Bay
68% of households in Thunder Bay own their home (Canada: 66%), and the median owner-estimated home value was $300,000 in the 2021 Census (Canada: $472,000). Market prices have moved since 2021, so treat the value as a 2021 reference point. That is close to the national mix of owners and renters. Lower home values tend to go with more price-aware buyers, so clear pricing, financing options and any rebates you can verify help.
Thunder Bay is in building climate zone 7A of the National Energy Code of Canada for Buildings (zones run from 4, the mildest, to 8). Environment Canada's 1981-2010 normals for FLINT (about 32 km away) show 5,683 heating degree days and 77 cooling degree days in a typical year, so heating is by far the larger load. For a spray foam or insulation contractor, a long, cold heating season tends to move what homeowners search for toward cold rooms, drafts, high heating bills and ice dams, and it makes air sealing and a well-insulated attic a year-round conversation rather than a seasonal one.
65% of occupied homes in Thunder Bay are single-detached houses (Canada: 53%), according to the 2021 Census. That is a market built around houses, which are where attic, wall and basement insulation work and new-build spray foam jobs mostly come from, so homeowner-focused pages and builder outreach both have a large audience here.
The 2021 Census counted 108,843 people in Thunder Bay, up 0.9% from 2016 (Canada: up 5.2%). That is slower than the country as a whole, so more of the work is likely to come from the existing housing stock, where retrofit and energy-bill messaging fits well, with new construction as a smaller second line.
Google Maps rankings change from one part of a market to the next, so being visible near your shop does not mean being visible across the whole service area of Thunder Bay. The free Market Visibility Audit shows your ranking at a grid of points around your business.
How the Google Maps grid works in a market like Thunder Bay
Google Maps does not show one ranking for a whole city. The result changes block by block, depending on where the searcher is standing. Our audit searches from a grid of points around your business and records where you appear at each one. Green means you are in the top 3 at that spot. Red means customers there are not finding you. In Thunder Bay, that grid is the check on whether you show up across the area you claim, not only beside the shop.
