TORONTO, -- The Ontario government is refusing to hear testimony from experts on noise and safety in an ongoing Environmental Review Tribunal, according to motions presented to the appellant. Last week, the Environment ministry and power developer NextEra filed motions to deny testimony from witnesses at an appeal launched by Esther Wrightman, a citizen of the Middlesex area. The ministry and developer are objecting to testimony from medical doctors, a professional engineer with expertise in noise measurement, an acoustician with knowledge of the effect of environmental noise and infrasound on human health, and real estate appraisers.
