Gas prices in Barrie and the Highway 400 budget

Where Barrie's figure comes from

Barrie sits on Highway 400 north of Toronto, at the edge of Lake Simcoe, outside both of the Toronto markets in the provincial survey. The province publishes the southern Ontario average every Monday, and that is the number that applies here. It is an average of a wide area, so local stations can be cheaper or more expensive than it in a given week.

A Highway 400 commute in a monthly budget

For a driver who heads down the 400 to the Greater Toronto Area several times a week, the useful unit is the month. Take one 65-litre fill-up a week as a simple example. That is about 282 litres a month, which at the estimate for October 27, 2026 comes to $484. Each cent per litre moves that monthly bill by $2.82, and over the last 13 surveys the average ranged across 24.5¢/L, which on this budget is a difference of $69 a month between the cheapest and the dearest week.

A budget built this way is easier to hold to than a price watch. Knowing that the commute costs roughly a fixed amount a month, and how much a ten-cent move shifts it, tells you whether a cheaper station on the way is worth the stop. Enter your own vehicle and yearly kilometres below; the result also gives the cost per 100 km.

Barrie against Toronto

Commuters can fill up at either end of the trip. The published averages put the southern Ontario figure 1.5¢/L below the Toronto blend at the latest survey. On a 65-litre fill-up that is $0.98, rarely worth a detour.

The proposed excise return in the commuter's budget

The federal excise tax on gasoline, 10 cents a litre, has been suspended since April 20, 2026. Finance Canada's draft legislation (proposed, not enacted) extends the suspension to January 31, 2027, brings back 5 cents on February 1, 2027 and the full 10 cents on April 1, 2027. HST is charged on top of it, so in Barrie the return is worth 5.65¢/L and then 11.30¢/L if nothing else moves. For the weekly fill-up in the example, that adds $32 a month from April 2027. The outlook page follows the schedule.

Taxes in a Barrie litre today

Until then, a litre of regular in Barrie carries Ontario's 9-cent gasoline tax and HST at 13% on the whole price, nothing more. The excise line reads zero for as long as the suspension lasts.
