Montreal gas prices may spike this weekend — Here are the cheapest places to fill up right now

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.
