It looks like diesel prices are heading up on Monday night in New Brunswick.

An industry source says the New Brunswick Energy and Utilities Board will use the interrupter clause at midnight.

The maximum price is expected to increase by more than seven cents per litre, said the source.

Diesel is currently selling for a maximum of $1.50 per litre in New Brunswick.

Gasoline prices will not be impacted by the interrupter clause. The maximum price for regular self-serve currently sits at $1.42 per litre.
