About the data

Source and licence

The data is the 2025 Mississauga Business Directory, published by the City of Mississauga on its open data portal. The City collects it through its annual business survey. It is released under the City of Mississauga Terms of Use (open data), which allows the data to be used, changed and shared for lawful purposes. KnowSauga is not affiliated with or endorsed by the City of Mississauga.

File used: 2025_Mississauga_Business_Directory.csv. This site was last built from it on 2026-11-12. The directory is updated about once a year, so some places will have opened, moved or closed since.

The city outline and the neighbourhood shapes on every map come from two more City of Mississauga open datasets, also under the Terms of Use: Municipal Boundary and Mississauga Official Plan (2010) Character Area and City Structure (downloaded 2026-11-12). We merge the planning shapes the same way as the area names, so each of the 42 areas has one shape; touching areas never share a colour.

Bus routes and stops on the Work Nearby maps come from MiWay's GTFS schedule feed (version 2, valid 2026-09-22 to 2026-12-20, downloaded 2026-10-09), also City of Mississauga open data.

What we show, and what we leave out

For each business we show the name, the type of business, the street address and unit, the phone number and website the City recorded, and the staff range. We never show email addresses or fax numbers, which are in the City's file, to keep businesses off spam lists.

Of the 14,637 rows in the file, we keep 14,629: we drop 2 rows named "Vacant" and 6 exact duplicates. One row has no neighbourhood and a ward of 0; it stays in city totals and on maps but on no neighbourhood page.

How we clean it

• Map positions. The City gives x and y in Web Mercator metres; we convert them to latitude and longitude. Dots are the directory's address points, not verified storefront locations.
• Labels that contradict the address. One row has a neighbourhood or main-street label that doesn't match where the business is (for example, a Streetsville label on an address near the airport). When a business sits more than 1 km from every other business on the same main street, we drop the main-street label; when it sits more than 3 km from every other business in the same neighbourhood, we use the neighbourhood of its nearest neighbours instead.
• Neighbourhood names. The City labels each business with a planning "character area" such as Port Credit CN or Churchill Meadows EA. We strip the planning suffixes (EA, CC, NHD, SA, CN, MN, SPA), expand "DT" to "Downtown", and merge east and west halves, which turns 57 labels into 42 areas. For example, Port Credit CN and the east and west halves of Port Credit NHD become one Port Credit. Areas whose labels are only employment or corporate-centre types are shown as business parks: Airport, Clarkson, Dixie, Gateway, Mavis-Erindale, Meadowvale Business Park, Northeast Employment Area, Sheridan Park, Southdown, Western Business Park.
• Industries. Each business carries a NAICS industry code and a sector. We fix three sector spellings the file uses inconsistently and give each sector a plain label (for example, "Accommodation" becomes "Restaurants, hotels and food services"). Where the file's description for a code is wrong (code 448120 is labelled "Quick Printing" but the businesses are clothing stores) we use the standard description for that code. 341 rows have no description on record, 285 of them no usable code at all; they appear as "Type not recorded" and sit outside every category but stay in totals.
• Names. 214 names had broken characters in the file (an apostrophe shown as "?", or "Café" shown as "Caf‚"). We repair those by rule and change nothing else about how businesses spell their names.
• Staff size. The City records a range (1 to 4, 5 to 9, and so on up to 1000 plus). 14,314 rows have an industry; a few have no staff range and are shown without one.

The 21 everyday needs

Near Me, the Everyday Score and the neighbourhood category pages use the same 21 categories, each defined by NAICS codes:

Counts on a neighbourhood page are listings inside that neighbourhood. A neighbourhood gets a page for a category only when it has 3 or more listings in it, so there are 452 neighbourhood-by-category pages rather than 882. On a category page, places are sorted by straight-line distance from the centre of the neighbourhood.

The chain rule

We call a business a chain when the same name appears at three or more Mississauga addresses. Names are compared after lower-casing, removing punctuation and store numbers, and dropping words like "Inc", "Ltd" and "Canada". That flags 196 names at 1,133 locations. A short hand-kept list adds 131 national brands that happen to have only two locations here (261 locations), so they don't show up as local originals. Everything else, 13,235 businesses or 90% of the directory, counts as independent. The rule is mechanical: a family business with three shops is counted as a chain, and a franchise with a unique local name is not.

The Everyday Score

For each area we take the centre point of its listed businesses (the median latitude and longitude, which stays inside the built-up part of an area even when the area is long or oddly shaped), draw a straight-line circle of 800 m around it, and count how many of the 21 everyday needs have at least one listing from anywhere in the city inside the circle. The score is out of 21. Business parks are scored but not ranked. The circle ignores roads, rail lines, rivers and the highways, so a real walk is longer; Near Me lets you run the same check from your own address.

On the neighbourhood list, the dot colours show the score: green for 18 to 21, orange for 14 to 17, red for 13 or fewer, and grey for business parks. Business parks get a score for the people who work there.

Walking times

Every walking time on this site is a straight-line estimate: we divide the distance as the crow flies by 80 metres per minute. A "10-minute walk" means 800 m in a straight line. Streets, the QEW, the rail corridors and the Credit River all get in the way, so the real walk is usually longer, sometimes much longer.

Known issues

• 704 rows have no postal code, so postal-code search can't find them (they still appear on maps and in lists).
• Residential streets with no businesses are not in the directory. When Near Me can't find an address in the directory, it asks OpenStreetMap's free search service and tells you so.
• 341 rows have no description on record and 315 no industry. They are shown as "Type not recorded" or "Industry not recorded".
• The directory counts locations, not companies: a bank with 20 branches is 20 rows. Staff ranges are per location and come from the City's survey, not from the businesses' filings.
• Some rows are public facilities (City Hall, fire stations, libraries, transit depots) rather than businesses. They stay in totals and on maps.

Corrections

The directory belongs to the City of Mississauga, which updates it once a year; we don't edit it. Spotted something wrong, in a listing or in our arithmetic or wording? Tell us.
