OTTAWA - Health Canada and Statistics Canada will conduct a study to evaluate the relationship between wind turbine noise and potential health effects even though Ontario has reviewed the technology.

In an announcement Tuesday, Health Minister Leona Aglukkaq said growing concerns among residents sparked the feds decision to take a close look at the noise created by wind turbines.

"This study is in response to questions from residents living near wind farms about possible health effects of low frequency noise generated by wind turbines," said Aglukkaq.

Ottawa Tory MP Pierre Poilievre coincidentally sent a letter to Ontario Premier Dalton McGuinty Tuesday to call for a moratorium on wind farms in the capital region.

"Until the completion of this Health Canada study, I am calling on a moratorium on the Marlborough Wind Farm project proposed for the village of North Gower, located in the City of Ottawa," he wrote.

Ontario Progressive Conservative MP Vic Fedeli also said the announcement of the federal study is a hit to

McGuinty's green energy plans and reiterated calls for wind power development to stop.

Wind power has already been studied in the province of Ontario but the review found no evidence of health impacts from the technology.

But Wind Concerns Ontario, an advocacy organization, now says approvals for large-scale wind turbine projects should be on hold until the federal study is complete. Results are expected in 2014.

Thousands of turbines are currently planned in Ontario, with multi-national companies planning to invest billions in the technology. However, there has been a moratorium on off-shore wind farms in the province since February 2011.
