How the change works
- 01 / Public decision
Closures and network security
- 02 / Physical change
Elimination of coal-fired generation
- 03 / Possible outcome
Electric mix with less carbon
The coordinated closure of power plants can reduce emissions, if the system maintains sufficient capacity with less emissive sources.
Research and local documents ↓What the evidence tells us
Ontario documents the transition from about 25% of coal supply in 2003 to zero in 2014.

Share of electricity, not percentage of CO₂. Zero concerns coal in the provincial supply.
Conditions and limits
The change involved nuclear, hydroelectric, renewables and gas. Weather and cross-border pollution complicate the attribution of air improvements.
Other possible benefits
Lower local pollutants and new system organization.
