To understand the price of natural gas, you need to understand its six components: natural gas supply, transportation, load balancing, distribution, inventory-related adjustments and cap-and-trade emission allowances system.


The supply is the natural gas itself, the fuel. The price fluctuates according to market supply and demand. The supply price is modified monthly. We bill you the same as what we pay the producers. Learn more on gas supply (PDF)


This is the service that sends the natural gas through pipelines from the production sites to Quebec , the territory served by Gaz Métro. The transportation prices are modified when Gaz Métro transportation suppliers modify their own prices. We bill this service at the same price as what we pay the transportation companies.

Load balancing means managing the variations between summer and winter consumption and natural gas storage management. This component's price is modified annually, at the beginning of October.Gaz Métro bills this component at the same price that the load balancing tools are bought from suppliers.

Cap-and-trade emission allowances services

The emission allowance cost for the natural gas combustion, which varies each month. Cap-and-Trade System is an economic tool of the Québec government aimed at reducing greenhouse gas emissions. Fuels consumed in Québec are covered by the Cap-and-Trade System through energy distributors like Gaz Métro. The sums collected will be invested by the government in, among other things, measures aimed at combating climate change.

Two components, supply and cap and-trade emission allowances system, are not regulated and follow market supply and demand. The distribution, load balancing and transportation tariffs are reviewed each year by Gaz Métro.  Any change in the tariffs has to be approved by the Régie de l’énergie.

The Régie de l’énergie has approved Gaz Métro’s Conditions of Service and Tariff. These terms apply to all of our customers and set out the conditions related to: natural gas services provided, billing and payment options, various applicable tariffs and rights and responsibilities.
