The Canadian Council of Ministers of the Environment have coordinated a new plan for reducing air pollution, according to this Communiqué, and also this Canadian Intergovernmental Conference Secretariat press release. The air pollution plan is based on the recommendations of a multi-party committee that included government, NGO, and industry experts. That report is not available, but may be soon. Check here, or sign up for their emails. The plan is "comprehensive" (though subject to provincial jurisdiction), will up air quality standards, and
[u]nder the new system, Canadians would have ready access to information about air quality through new public reporting, modeling and monitoring mechanisms. This system would facilitate discussions with the United States on air pollution that crosses the Canada-US border.
The Ministers also approved a Water Action Plan that will be implemented in 2011.
