On March 23, 2015 the Vice-Chair of the Ontario Municipal Board (OMB), Susan de Aveller Schiller issued a historic ruling. By her denial of Amendment 106 of the Niagara Falls Official Plan, it rescued what the Sierra Club of Ontario has termed “the Green Life Line”. This is a narrow green corridor between the northern and southern parts of the eastern edge of the Niagara Escarpment.
There is only a thin green lifeline of farmland and forests between the Welland Canal and the Niagara River south of the Niagara Escarpment. This lifeline is only 1.7 kilometres in width. It stretches from the forested buffer of a landfill/quarry and the Queen Elizabeth Expressway. According to the Ministry of Natural Resources (MNR), Natural Heritage Guidelines, this is the bare minimum for a wildlife corridor, using the findings of the respected ecologist Reid Noss.
