If you are needing to fill up your gas tank this morning, it’s going to come with a bit of a surprise, one that isn’t good news.

The interrupter clause was invoked overnight by the Energy and Utilities Board spiking the price at the pumps by 7.7 cents a litre.

The maximum cost for regular self-serve now sits at 183.2.

This comes just two days after a carbon tax increase raised prices by over three cents a litre.

Diesel and furnace oil prices were not affected.
