Gas heading up to 133.9

The price of a litre of regular gas in Montreal is on the way up on Monday.

It's expected to go up to 133.9 cents, up from an average of 122.4.

Last week, the weekly gas price spike saw prices soaring to 131.9.

Some stations in the Montreal area have already made the change. Just about everyone will have made the change by the morning rush hour on Tuesday.
