Gas prices will again hit a new record high this week.
Effective Thursday, a litre of 87 and 90 gasoline will increase by $4.50.
This is the first time the ex-refinery rate for 87 has exceeded $200 per litre.
However, diesel, ultra low sulphur diesel and kerosene will decline by $0.25.
Propane will see $1.24 shaved off its price and butane will sell for $2.44 less.
These prices reflect the highest in 18 years.
