To answer that very quickly, there are national systems in place from the Meteorological Service of Canada under which there are 700 different monitoring stations across Canada. Those are in both rural areas and urban areas. There's greater concentration and monitoring in urban areas, but there's coverage in rural areas as well. Those collect data on pollutants, criteria pollutants, levels of greenhouse gas emissions, and others. So it's a complicated network.
In terms of the AQHI, the pilots have finished. The rollout is across Canada. The first stage to 2011 is to get at the communities of 100,000 and over. My understanding from the department is that after that first stage is finished, they want to go to fuller coverage, including rural areas.
