Canada FAQs
What is the average natural gas bill in Ontario?
The average Ontario household on Enbridge gas pays approximately $130 to $180 per month during winter (November to March) and $30 to $50 per month during summer. The annual average is roughly $1,400 to $1,800 per year for a home using 2,200 m3 annually. This includes the $23 monthly customer charge, gas supply, delivery, storage, and 13% HST.
How much does the carbon tax add to my gas bill?
The federal carbon charge adds approximately 12.4 cents per cubic metre to your natural gas bill. For a household using 2,200 m3 per year, the carbon tax portion is about $273 per year or $23 per month on average. The Climate Action Incentive Payment (CAIP) rebate is intended to offset this cost for most Canadian households.
Why is my Enbridge bill higher than just the gas rate?
Your Enbridge bill includes multiple components beyond the commodity (gas supply) charge. The $23 monthly customer charge applies even if you use no gas. Delivery charges cover pipeline maintenance. Gas supply cost recovery adjustments, storage charges, and transportation charges also apply. Finally, 13% HST is added to the total. The commodity charge is typically only 40% to 50% of your total bill.
What is the average natural gas usage in Alberta?
Alberta homes use more natural gas than other provinces due to colder winters and lower gas prices. The average Alberta household uses 110 to 130 GJ per year (approximately 2,900 to 3,400 m3). Monthly usage ranges from 2 to 4 GJ in summer to 15 to 22 GJ in January. The average annual gas bill in Alberta is $1,200 to $1,600 at current market rates.
How can I reduce my natural gas bill in Canada?
Lower your thermostat by 2 degrees to save 5% to 10% on heating costs. Seal air leaks around windows and doors. Upgrade to a high-efficiency condensing furnace (96% AFUE or higher). Install a programmable thermostat and reduce temperature overnight. Consider a home energy audit through NRCan programs, which may qualify you for rebates on insulation and equipment upgrades.
Does FortisBC charge differently from Enbridge?
Yes, FortisBC uses a different rate structure. The basic charge is $13.44 per month (lower than Enbridge). The commodity rate is adjusted quarterly based on wholesale gas prices. Delivery charges are tiered by consumption. BC also applies a provincial carbon tax separately from the federal carbon price. Total costs in BC tend to be similar to Ontario but the breakdown differs.
When is natural gas cheapest in Canada?
Natural gas commodity prices are typically lowest in late spring and summer (May to August) when heating demand drops. However, your monthly fixed charges remain the same year-round. If you are on a fixed-rate contract, your supply cost does not vary. Variable-rate customers may see supply charges drop to $0.80 to $1.00 per m3 in summer compared to $1.30 to $1.60 in winter.
