The provincial New Democrats used World Water Day to re-affirm their opposition to Bruce Power's plan to ship 16 steam generators on the Great Lakes to Sweden.
NDP Leader Andrea Horwath stood up in the Legislature on Tuesday to call on the McGuinty government to oppose the shipment as well.
Horwath says the plan is an unnecessary risk to a source of drinking water for 40 million people.
She also cites strong opposition by environmental groups, mayors and Aboriginal communities to the proposed move by Bruce Power.
The Anishinabek Nation has launched a blue ribbon campaign to stop the shipment and claims they have never been consulted.
Ontario Energy Minister Brad Duguid says he wrote a letter to the Canadian Nuclear Safety Commission to ensure the safety concerns of Ontarians were addressed.
Duguid defended his actions by saying CNSC was the authority on the matter.
But Duguid also attacked the New Democrats by suggesting they had an opportunity to express their concerns to the CNSC -- but never bothered to say anything.
Bruce Power wants to ship the 16 steam generators -- each the size of a school bus -- from its Tiverton plant to Sweden, through the Great Lakes and along the St. Lawrence.
