Average Canadian gasoline prices are less than a penny a litre away from their all-time highs, according to a weekly pump-price survey released Tuesday.

The national average cost of a litre of regular gas rose to $1.252 a litre, up 2.2 cents from last week, Calgary-based MJ Ervin & Associates said.

The record high in MJ Ervin's weekly look at pump prices came in September 2005, in the aftermath of Hurricane Katrina. The average price then: $1.26 a litre.
