New Report From Ontario's Chief Medical Officer Of Health Says There Is No Direct Causal Link Between Wind Turbines And Adverse Health Effects

Ministry of Health and Long-Term Care

The scientific evidence does not demonstrate any direct causal link between wind turbine noise and adverse health effects according to a new report from Dr. Arlene King, Ontario's Chief Medical Officer of Health.

The report was prepared by the Chief Medical Officer of Health and in consultation with the Ontario Agency for Health Protection and Promotion, the Ministry of Health and Long-Term Care and the Council of Ontario Medical Officers of Health.  The report summarizes the scientific evidence on the potential health impacts of wind turbines.

The report concludes that:

  • While some people living nearby wind turbines report symptoms such as dizziness, headaches and sleep disturbance, available scientific evidence to date does not demonstrate a direct causal link between wind turbine noise and adverse health effects.
  • The sound level from wind turbines at common residential setbacks is not sufficient to cause hearing impairment or other direct adverse health effects, but it may annoy some people.

Quick Facts

  • The Ministry of the Environment regulates wind turbines in Ontario.
  • The minimum setback distance for wind projects is 550 meters; this intends to ensure noise levels do not exceed 40 decibels at the nearest residence.
  • Forty decibels is approximately the noise level experienced in a quiet office or library.
  • Ontario has over 690 wind turbines.
