RE: HEALTH CANADA WIND TURBINE NOISE STUDY
AN OPEN LETTER TO
The Right Honourable Stephen Harper, Prime Minister email@example.com
The Honourable Rona Ambrose, Minister of Health firstname.lastname@example.org
Contradictions and bias undermine credibility of the
Health Canada Wind Turbine Noise Study
The Multi-municipal Wind Turbine Working Group is comprised of elected municipal
councillors and appointed citizens from parts of Southern Ontario where
approximately 30% of industrial wind turbines are concentrated. Over the past
several years we have received a growing number of delegations from constituents
whose health has been adversely affected by proximity to the wind turbines. It is not
easy to listen to people who continue to suffer from ringing and pressure in the ears,
pounding vibrations in the head and chest, nausea, dizziness and the ongoing
inability to sleep. Their stories are especially disturbing because we know these
people; we know they are not lying; and it is our responsibility under the Municipal
Act to protect their health.
We are dismayed that the recently released Health Canada Wind Turbine Noise and
Health Study has ignored the distress of real people by hiding behind meaningless
“estimated” noise projections and predictive modeling rather than first making
professional clinical observations based on the histories of actual sufferers.
Investigation of anecdotal evidence is the foundation of all medicine.
The Health MULTI-MUNICIPAL WIND TURBINE WORKING GROUP Page 2 of 4
Canada study summary contains no reference to the growing body of research that
contradicts the main theme of the summary. Our Grey-Bruce Medical Officer of
Health, Dr. Hazel Lynn has found 18 peer-reviewed studies that “provide reasonable
evidence . . . that an association exists between wind turbines and distress in
humans”. The Brown County (Wisconsin) Board of Health has declared its wind
turbines a “public health nuisance” and a “human health hazard for all people . . .
who are exposed to Infrasound/Low Frequency Noise and other emissions
potentially harmful to human health”.
Key findings contradict summary of results
The key findings have been released without data for verification and without peer
review. Epidemiologists have pointed out that the study lacks scientific credibility.
Gaps, biases and errors in methodology make it unreliable. For example, only 1234
out of the 2004 dwellings selected responded to the survey compromising its
validity. Only 20% of the homes studied were “near” turbines. And yet homes up to
10 kilometres away were included, diluting the results from the homes near the
turbines. And the serious issues of low frequency noise, cyclical sound and
amplitude modulation were simply overlooked.
At the same time, the study contradicts itself. It found that wind turbine noise is
“statistically related to several self-reported health effects including blood pressure,
migraines, tinnitus, dizziness, and disturbed sleep”. And yet the key findings which
have been widely publicized claim that “no evidence was found to support a link
between exposure to wind turbine noise and any of the self-reported illnesses”.
Does Health Canada no longer advocate the precautionary principle which calls for
rigorous caution when the safety of any group is even remotely threatened,
acknowledging that lack of full scientific certainty should not be used as a reason for
postponing measures to protect them?

It is our belief that that the premature marketing of the key findings has been a
disservice to the people of Canada, an insult to those who continue to suffer the
adverse effects of the turbines, and has resulted in loss of respect and credibility for
Health Canada. We await your explanation as to how Health Canada came to its
conclusion that there are no health problems when obviously there are.
