Regulated gas prices in Atlantic Canada: how it works

Who sets the prices

A quick geography note first: the Maritimes are three provinces, New Brunswick, Nova Scotia and Prince Edward Island. Add Newfoundland and Labrador and you get Atlantic Canada. All four regulate the price of gas, each through its own body:

• New Brunswick: the NB Energy and Utilities Board
• Nova Scotia: the Nova Scotia Energy Board
• Prince Edward Island: the Island Regulatory and Appeals Commission (IRAC)
• Newfoundland and Labrador: the Public Utilities Board

A ceiling, or a range

In New Brunswick and Newfoundland and Labrador, the regulator sets a maximum price. A station can't charge more, but nothing stops it from charging less.

In Nova Scotia and Prince Edward Island, it's a range: a minimum price and a maximum price. Each station picks its price within that window. In all four provinces, the calculation follows wholesale prices, with the allowed margins and taxes added on top.

Zones, and not the same number everywhere

Because it costs more to truck gas to some regions than to others, some provinces divide their territory into zones, each with its own price.

Nova Scotia has six zones: Halifax, Kentville, Yarmouth, Amherst, New Glasgow and Sydney. New Brunswick and Prince Edward Island each have a single zone for the whole province. Newfoundland and Labrador, with all that territory to cover, has about twenty.

When prices change

Prices don't change whenever they feel like it. Each regulator has its own rhythm:

• New Brunswick: every Friday at 12:01 a.m.
• Nova Scotia: every Friday
• Prince Edward Island: Tuesdays and Fridays
• Newfoundland and Labrador: every day, since March 2026

The interrupter clause

The schedule has a safety valve. In New Brunswick and Nova Scotia, when wholesale prices move a lot between two scheduled dates, the regulator can adjust prices without waiting for the next Friday. That's called the interrupter clause.

So if you see the price change on a Wednesday, nobody got the calendar wrong. And it works both ways: a sharp drop in wholesale prices can bring the maximum down early, too.

What it means for you

A maximum price isn't the price: it's a ceiling. In practice, the pump price often sits close to the maximum, but a station is allowed to sell below it (down to the minimum in Nova Scotia and Prince Edward Island).

So comparing is still worth it, even in a regulated province. And if you drive from one zone to another in Nova Scotia or Newfoundland and Labrador, the ceiling itself changes, so it's worth checking where you'll fill up before you head out.

How Gazo shows it

Outside Quebec, real prices in Gazo come from drivers who report them. A reported price is shown as is for 72 hours, after which it's considered out of date.

When a station in New Brunswick, Nova Scotia or Prince Edward Island has no recent price, Gazo shows the regulated price for its zone, labelled “Estimate: regulated maximum price.” In Nova Scotia and PEI, that's the top of the range. The estimate is never ranked among real reported prices: it's a reference point, not a leaderboard.

Two honest caveats. Gazo assigns each station to the zone whose centre is closest, which can be off near a zone boundary. And in Newfoundland and Labrador, zone prices are only published as PDFs that Gazo doesn't read yet. For now, the estimate shown there is the Statistics Canada average for St. John's or the nearest city, and the label says so.

The best way to get a real price is still to report one. When you come back to Gazo after heading to a station with the “Go” button, the app asks whether the price was right. A few seconds for you, a real price for everyone who stops there after you.
