  • The provincial government's cap-and-trade program puts a price on greenhouse gases (GHG) emitted by Ontario homes and businesses.
  • Union Gas is required to buy emission allowances for the natural gas you use in your home and to pass this cost on to you. These costs will be included on your natural gas bill.
  • The added cost is expected to be about $70 to $80 per household in 2017* and to increase over the long term as the cap on GHG emissions is lowered.
  • The actual incremental cost will depend on how much natural gas you use.
  • This additional cost will be included in the Delivery charge on your natural gas bill.
  • Union Gas can help you reduce the cost of cap and trade, and lower your natural gas bill, by improving the energy efficiency of your home. Visit to find out how.

Now's the time to check fuel-burning equipment

Carbon monoxide (CO) is a poisonous gas that can build up in your home if your fuel-burning equipment is malfunctioning or poorly vented. You can't see it or smell it, so it's important to take steps to keep your family safe.

A technician inspects a piece of fuel burning equipmentStep #1: Inspect
Have all fuel-burning equipment inspected - and repaired, if necessary - by a Technical Standards and Safety Authority (TSSA) registered heating contractor every year.

It's the law Install CO alarms on every level of your home, especially near sleeping areas, since most carbon monoxide poisonings happen while families are asleep. And don't forget: CO alarms can't detect a natural gas leak. For that, you need a natural gas alarm or combined CO/natural gas alarm.
Person checks for blockages in an exhaust ventStep #3: Check
It’s important to keep outside exhaust vents, flues and chimneys clear of nests, leaves or other build-up.

Blocked sewer? Make the right call

Before attempting to clear a blocked sewer outside the walls of your home, be sure to call for a safety inspection. Your natural gas line may cross through the sewer pipe under your lawn. Cross bores are normally not a safety risk. But if your plumber's motorized or water-jetting equipment hits the gas line, it could cause a leak - a potentially dangerous situation.
