I wish to stress that I am not a dogmatist opposed to financial incentives, trading mechanisms etc. to protect the environment. During the NDP government in Ontario there was a push for phosphorous trading to reduce pollution, which was actually taken up by one conservation authority, South Nation, between Ottawa and Montreal. In all the rest of the province, including Niagara it went nowhere. This is because it did not fit into the agendas of the same sort of construction interests here that are pushing biodiversity offsetting. They correctly understood that phosphorous trading would mean less money for expensive construction activity, such as separating storm and sanitary sewers, and wanted to hog the money for themselves, and not let rural landowners benefit from measures such as paying for treed buffer strips.
