St. John's gas prices are capped by the Board of Commissioners of Public Utilities of Newfoundland and Labrador, which sets a maximum for each zone; St. John's is in Zone 1, the Avalon Peninsula. The figure here is that ceiling, taxes included, and stations may sell below it. The cap dated October 24, 2026 is 202.5¢/L for self-serve regular and 284.6¢/L for diesel. The Board normally resets prices every Friday, but since October 2026 it has been setting them every day because of market volatility, so a new maximum is expected for October 27, 2026 and the page repeats the current one until it is published. Premium is taken from Statistics Canada's monthly average for St. John's, 219.5¢/L for September 2026, brought to 210.3¢/L with the wholesale change; over 25 months the method erred by 2.0¢/L on average. Tax is 16.7% of a litre of regular: 7.5 cents of provincial gasoline tax and 15% HST, the federal excise being suspended since April 20, 2026.
The Zone 1 cap
Newfoundland and Labrador divides the province into pricing zones, and the Board of Commissioners of Public Utilities sets a maximum retail price in each. St. John's belongs to Zone 1, on the Avalon Peninsula. The price on a sign in the city can be lower than this cap, never higher, and the cap already includes all taxes.
| Fuel | Latest official figure | Date and source | Estimate for October 27, 2026 | Past error of the method |
|---|---|---|---|---|
| Regular gasoline | 202.5¢/L | maximum price in force since October 24, 2026 · Board of Commissioners of Public Utilities (Zone 1, Avalon) | 202.5¢/L | ±2.0¢ on average over 25 months ("no change" guess: ±6.6¢) |
| Premium gasoline | 219.5¢/L | September 2026 average · Statistics Canada | 210.3¢/L | ±2.0¢ on average over 25 months ("no change" guess: ±6.6¢) |
| Diesel | 284.6¢/L | maximum price in force since October 24, 2026 · Board of Commissioners of Public Utilities (Zone 1, Avalon) | 284.6¢/L | ±3.9¢ on average over 25 months ("no change" guess: ±8.9¢) |
For a measure of what was actually paid, Statistics Canada's monthly average for regular in St. John's was 213.7¢/L for September 2026. Set against the cap dated October 24, 2026, that is +11.2¢, but the two describe different periods, a past month and the current day.
A daily reset, for now
The Board's usual rhythm is weekly, with new maximums each Friday. Since October 2026 it has been resetting them every day because of market volatility, which means the St. John's cap can change overnight. A new maximum is therefore expected for October 27, 2026. Until it is published, the page keeps the cap in force rather than guessing the next one. When the Board returns to its weekly schedule, the page will follow it.

Diesel on the Avalon
Diesel is capped at 284.6¢/L, 82.1¢/L above regular. Part of the gap is tax: the province charges 9.5 cents a litre on diesel against 7.5 on gasoline, rates made permanent by a statute assented on March 30, 2026, and HST at 15% then applies to a higher base. Taxes are 16.4% of the diesel cap.
| Component | Per litre |
|---|---|
| Newfoundland and Labrador gasoline tax | 9.50¢/L |
| Federal excise tax | 0.00¢/L |
| Sales tax (HST, 15%) | 37.12¢/L |
| Refined product, transport and margins | 237.98¢/L |
| Pump price | 284.6¢/L |
The federal excise on diesel, 4 cents a litre before its suspension, is lower than on gasoline. When it returns in full on April 1, 2027 under Finance Canada's draft legislation (proposed, not enacted), it adds 4.60¢/L with HST on diesel and 11.50¢/L on gasoline. The diesel page covers the fuel nationally.

Premium, from a different source
The Zone 1 cap the site reads covers regular and diesel only, so premium comes from Statistics Canada's monthly average for St. John's: 219.5¢/L for September 2026, carried to 210.3¢/L with the wholesale change since then. It is an estimate and is labelled so.
Filling up at the cap
Because the cap is the highest price allowed, it gives an upper bound on what a fill-up can cost in St. John's this week. A 55-litre tank of regular costs at most $111.38, a 90-litre pickup tank of diesel at most $256.14. If the sign shows less, enter it below to see the actual bill.
