TORONTO - Ontario is creating a Great Lakes Guardians' Council to improve collaboration among governments, agencies and First Nations around the world's largest supply of fresh water.

Environment Minister Glen Murray says there have been dramatic changes in water levels in the Great Lakes in recent years because of climate change, which will require new infrastructure to protect the drinking water supply.

Murray says right now there is no overall provincial body that brings together all the governments and parties involved in the Great Lakes.

He says the Guardians' Council will identify priority areas that need action and help find funding sources for the projects.

But the Progressive Conservatives say there's so little detail in the Great Lakes Protection Act it's like an old episode of Seinfeld -- "much ado about nothing."

The New Democrats say people are tired of 12 years of Liberal rhetoric on the Great Lakes and want to see real progress.
