The Canadian government is failing to protect its citizens from toxic chemicals and pesticides, according to a damning report released yesterday by Brian Emmett, the nation’s commissioner of the environment and sustainable development. He criticized the government for relying on an ineffective system of voluntary programs to measure and reduce toxics, and for failing to track pesticide sales and review pesticides to ensure they meet safety standards. The report comes as the government is considering toxics legislation that environmentalists say is far too lax.
