Ontario's Independent Electricity System Operator said wind-powered electricity generation doubled last year, and the province will get more power from wind in the year to come.
The overseer of Ontario's electricity market said more wind power is scheduled to come online this year to boost the province's supply.
But Ontario residents are still relying heavily on nuclear generation, with more than half of the province's supply coming from such facilities.
Some 18 percent of the province's electricity supply came from coal-fired generation, which was up slightly from 2006.
Although the province is pushing energy conservation, residents used slightly more electricity last year than they did in 2006.
