Ontario is now accepting applications for commercial-scale carbon storage projects, marking a major step toward reducing industrial emissions while supporting jobs and investment.
The Ontario Ministry of Natural Resources says the projects would capture carbon dioxide produced by energy-intensive industries and store it deep underground in natural rock formations, preventing it from being released into the atmosphere.
In practice, carbon storage works by capturing emissions at facilities such as cement plants, refineries, or steel manufacturers. The carbon dioxide is compressed into a dense form, transported by pipeline or truck, and injected thousands of metres underground into porous rock layers, similar to how oil or natural gas has been stored for millions of years. Impermeable rock layers above the storage zone act as a natural seal, keeping the carbon permanently contained.
The province estimates the technology could reduce greenhouse gas emissions by five to seven million tonnes annually, create more than 4,000 jobs, and save Ontario industries nearly $1 billion by helping them meet climate targets without relocating operations.
Ontario officials say the regulatory framework was developed through years of research, public consultation, and stakeholder engagement, including municipalities, Indigenous communities, and landowners. Most carbon storage potential is expected in southwestern Ontario, where many of the province’s largest industrial emitters are located.
Globally, carbon capture and storage is already in use, with hundreds of projects operating or under development worldwide. Ontario says opening applications positions the province to attract investment while maintaining environmental protections and supporting a competitive, low-carbon economy.
