OTTAWA - The average cost of a litre of gasoline in Canada has dropped below $1 for the first time in nearly four and a half years, according to price monitoring website GasBuddy.com.

While many locations across the country have seen prices below that mark for a couple of weeks, Thursday was the first time since Aug. 30, 2010, that the average dipped to 99.9 cents.

In a statement, the website operator says Thursday also marked the 77th consecutive day that the national average has declined.

GasBuddy says average prices are about 28 per cent below the peak of $1.39.3, reached on June 22.

To put that in perspective for the average motorist using 80 litres of gasoline per week, the savings between the June peak price and Thursday's average works out to between $35 and $40 weekly.

The milestone may be short-lived, however, as prices are expected to increase by up to two cents per litre in many parts of the country by Friday.
