In May 2015, the Cities Initiative issued a statement on the Deep Geologic Repository for nuclear waste near Kincardine, Ontario. The Deep Geologic Repository (DGR) is a proposed nuclear waste storage facility that would be located deep underground near the Great Lakes.
In 2010, the Cities Initiative commented on the Bruce Power Shipment of nuclear waste. The Bruce Power nuclear plant in Bruce County, Ontario, proposed a shipment of contaminated steam generators from its plant to a facility in Sweden. The Cities Initiative expressed concern about the safety of shipping this large quantity of contaminated nuclear material through the Great Lakes Region.
