TORONTO - A southwestern Ontario family is suing over a wind farm they claim is damaging their health.

The Michaud family of Thamesville claims they have suffered vertigo, nausea and sleep disruption caused by the Kent Breeze wind farm.

The wind farm, which began operating in May 2011, consists of eight turbines, the closest of which is 1,146 metres from the Michaud's property.

In a statement of claim filed Tuesday in Toronto, the Michauds claim the wind farm constitutes a nuisance and is a non-natural use of the neighbouring property.

The statement of claim, which contains allegations that haven't been proven in court, says the effects of the wind farm have caused pain and suffering and loss of enjoyment of normal use of their property.

The family is seeking damages totalling $1.5 million from defendants Kent Breeze Corp., MacLeod Windmill Project Inc. and Suncor Energy Services Inc. and wants the court to shut down the wind farm.
