Thank you very much for the question.
Yes, Health Canada partners in a number of ways with Environment Canada and others on the environmental file, because there's often a concern on both the environmental and human health sides. Environment tends to be the lead department, but we are very much, we think, an important partner in a number of environmental activities. Certainly one of the ones that's in these estimates is something that's very specific to air quality.
There is a need for additional research to support the development and refinement of an indicator that would help us measure the connection between air quality and health, because I think that understanding which conditions are linked in the epidemiological research to which air quality indices or air quality findings is critical to taking action. So the research function of a new health air indicator we think is quite important. It would allow us to track changes over time in air pollution levels, for example, and to see what links those might have to the health of Canadians.
So there is actually $240,000 in supplementary estimates (B) for the expansion of this indicator to include other pollutants. It's an ongoing piece of work that we are doing. Currently, we have an air quality indicator for ozone and for particulate matter, but we are working to expand that as part of our overall clean air agenda in terms of the work we do with Environment Canada under the chemicals management plan and the work we do on the environmental and health files generally.
