Ontario's chief medical officer of health says there's no evidence that the noise from wind turbines leads to adverse health effects.
Dr. Arlene King says some people living near wind turbines may report symptoms such as headaches, dizziness and sleep disturbances.
But she concludes in a new report that the noise of wind turbines at common residential setbacks isn't sufficient to cause hearing impairment or other health effects.
The governing Liberals have been pushing wind turbines and other sources of renewable energy as part of a larger plan to reduce greenhouse gas emissions and boost the economy.
Residents from across the province had been lobbying the government to impose a moratorium on new wind projects until the possible impacts on human health were studied.
Hundreds of protesters rallied last month at the legislature saying the province was overriding the concerns of local councils across Ontario about wind projects.
