Why a Winnipeg-only price tracker

Gas in Winnipeg is sold along a handful of busy arterials. Pembina Highway, McPhillips Street, Regent Avenue, Kenaston Boulevard and Portage Avenue West each carry clusters of stations that watch one another, while the pumps on quiet residential corners and in the downtown core face far less pressure. On the same afternoon, a station on one of those strips and a station a few kilometres away can be several cents per litre apart. That spread is the thing this site is built to show.

Two local players shape the low end of the market. Red River Co-op is a Winnipeg-based consumer co-operative with gas bars across the city, and its member equity means a member’s real cost can sit below the posted price. Costco runs membership-only gas bars, including sites on Regent Avenue West and McGillivray Boulevard, whose prices are often among the lowest we record. Neither is right for every driver, so we list both alongside the majors, the independents and Winnipeg’s own Domo, and let you weigh them.

Tax is a smaller part of the story here than in some provinces. Manitoba charges a provincial fuel tax of 12.5¢/L, applies no PST to gasoline, and the federal consumer carbon charge was removed on April 1, 2025. Those per-litre amounts don’t change from day to day, so the swings you notice week to week come mostly from wholesale costs and retailer pricing decisions. Our Manitoba gas-tax explainer breaks down what is in a litre.

What we are, and what we are not

CheapGasWinnipeg.ca is a website, not a retailer. We don’t sell fuel, we aren’t owned by an oil company, and no station or brand pays us to appear or to rank higher. The site is paid for by display advertising. Advertisers have no say over the station lists: stations with a recent report come first, ordered by price, and distance only enters the ordering when you search from a location.

Where each price comes from

We do not survey stations ourselves. Every pump price on this site started as a report from a driver on GasBuddy, the community price-reporting service. What we add is collection, checking and presentation:

An hourly collection pass. Once an hour our server reads the GasBuddy reports for Winnipeg station by station. Because a single citywide search tends to miss stations at the edges, the pass also runs searches centred on outlying neighbourhoods such as Transcona, St. Vital, St. James, Fort Richmond, Charleswood, The Maples and Sage Creek, then repeats the process for Headingley, Selkirk, Stonewall, Oakbank, Niverville and Steinbach. Each price keeps the time the driver posted it.
A top-ten check between passes. CBC Manitoba’s gas-prices page embeds a GasBuddy widget listing Winnipeg’s ten cheapest reports. We read it every hour too, so a fresh low price can reach the site without waiting for the full pass.
The station list. Station locations come from OpenStreetMap, imported for the area running from Selkirk and Stonewall in the north to Niverville in the south. A priced station and an OpenStreetMap entry are treated as the same place when they sit within about 120 metres of each other and carry a compatible brand, which keeps the map free of duplicate pins. Stations nobody has reported on appear without a price.
A plausibility filter. Community reports occasionally contain jokes and typos. Any value outside 60–350¢/L is thrown out, and reports entered in dollars (“1.64”) are converted to cents instead of being read as 1¢.
Age limits. A price older than 36 hours drops out of the cheapest-today ranking; prices reported within the last 12 hours rank ahead of older ones; and a station with no new report for 14 days has its price cleared rather than left on display.

We began storing these observations in late July 2026, so our price history starts there. Charts on the site show recorded observations only; we don’t fill earlier periods with estimates.

Coverage

The core of the site is regular unleaded inside the City of Winnipeg. Premium, mid-grade and diesel appear wherever drivers have reported them, which is less often, so those lists are thinner. Pages for Headingley, Selkirk, Steinbach, Stonewall, Oakbank and Niverville exist for drivers who live or fill up just outside the city; a town page only goes into our sitemap once enough of its stations have prices to make a comparison meaningful. Brands you will see include:

Red River Co-op
Costco
Domo
Shell
Petro-Canada
Esso
Mobil, including Superstore gas bars
Canadian Tire Gas+
7-Eleven

Each price page shows how many stations it is based on, so you can judge the sample. Quiet stations, especially on residential streets and in small towns, can go days without a report. If a station is missing or sits in the wrong spot on the map, please tell us.

The forecast is a rule of thumb

The fill-up-or-wait page combines our daily Winnipeg median with crude-oil and wholesale inputs using a few simple, published rules. It is a heuristic, not a promise, and the page explains exactly how it is calculated and when its inputs are missing.

Your location and your email

The nearby-stations search uses your coordinates only to answer that one request. They are not written to our database, not attached to a profile and not sent to analytics, and our web server does not log the API requests that carry them. If you sign up for price alerts, your email address is used to send the alerts you chose and nothing else. The Privacy Policy has the details.

How we check what we publish

Articles and explainers on this site draw on public sources rather than insider knowledge; we have no access to how refiners or retailers set their prices. We keep reported pump prices separate from our own calculations, and anything forward-looking is labelled as an estimate. The sources we check against are:

Pump prices: the time-stamped GasBuddy reports behind each station card.
Wholesale prices: Petro-Canada’s posted rack price for its Winnipeg terminal, with Natural Resources Canada’s wholesale series as a backup.
Crude oil: the West Texas Intermediate spot series (DCOILWTICO) published through the Federal Reserve Bank of St. Louis’s FRED database, which carries U.S. Energy Information Administration data.
Taxes: Government of Manitoba and federal publications, including the 2024 provincial fuel-tax holiday and the 12.5¢/L rate that took effect on January 1, 2025.
Competition questions: Competition Bureau Canada’s published work on retail fuel markets.

Nobody can pay for coverage in an article, and we don’t run sponsored posts. Each article carries a “Last reviewed” date showing when it was last checked.

Corrections

If something we published is wrong, send it through the contact form. When a correction changes a fact — a number, a tax rate, a quote attributed to the wrong source — we fix the article, update its review date and add a short dated note explaining what changed. Spelling and formatting fixes are made without a note.

Questions

Most common questions are answered in the FAQ. For anything else, including a station we don’t list, use the contact page.
