Cap and trade
What you need to know about Ontario’s carbon market using a cap and trade program, including how it works and who is required to participate.
Learn the basics of cap and trade
We have developed a plan to wind down the program.
Contact us if you have any questions.
Our cap on the amount of greenhouse gas emissions businesses can emit (using a cap and trade program) is designed to help fight climate change and reward businesses that reduce their greenhouse gas pollution.
We’re investing all of our carbon market proceeds into projects to reduce greenhouse gas pollution. See the latest announced projects
Linking with Quebec and California
We signed a cap and trade linking agreement with Quebec and California on September 22, 2017. It comes into effect on January 1, 2018.
Linking the carbon market means that:
- we will hold joint auctions of allowances with Quebec and California
- allowances and credits issued by us, Quebec and California will now be accepted by any of the three cap and trade programs
The first joint auction with all three jurisdictions is February 21, 2018.
Businesses covered under cap and trade
You’re required, by law, to participate in the cap and trade program if you are:
- an electricity importer
- a facility or natural gas distributor that emits 25,000 tonnes or more of greenhouse gas emissions per year
- a fuel supplier that sells more than 200 litres of fuel per year
Participation in the cap and trade program isn’t mandatory if you’re a facility that generates more than 10,000 but less than 25,000 tonnes of greenhouse gas emissions per year.
You can choose to opt in to the program and will be subject to the same rules as mandatory participants.Register to be a voluntary participant
Even if your company doesn’t have emissions to report, you can still participate in the auction as a market participant.
Market participants can include individuals, not-for-profit organizations and companies without compliance obligations.
