Yes, Mr. Mulcair, the absence of a common sustainable development strategy nationally is an impediment to making progress on a number of environmental fronts. Canada promised at an international forum in Rio de Janeiro in 1992, and at the World Summit on Sustainable Development in 2002, in Johannesburg, South Africa, and on several other occasions to introduce a national sustainable development strategy. By strategy, I mean a legislative frameworkâideally for sound environmental governance. From that would flow a host of environmental benefits, because the environment, as it's trite to say, knows no borders. A host of environmental benefits could flow across the country and be coordinated. That's certainly something in the way of a policy that's been long overdue and long promised in this country.
