As global oil markets react to war in Iran, rising gas prices have become the norm in recent weeks, and Montreal is no exception.
According to CAA, the average price for a litre on the island sits at $1.73 today. For context, the national average is around $1.56/L. CAA-Quebec also puts the current “realistic price” — based on acquisition costs and average retail margins over the past 52 weeks — at $1.79/L, suggesting most Montrealers are already paying less than they technically should be.

That gap may not last long. Gas Wizard is predicting the average price will climb to $1.79 per litre by Sunday, meaning what’s currently the realistic price could soon become the actual one.
