Yes, I do.
I want to just explain a little bit or elaborate a little bit on Environment Canada's role and academia's role. When it comes to long-term monitoring of something, that seldom gets research grants from the large research-granting councils either at the federal level or at the provincial level, because it's not the research of most interest. So when you're talking about wanting ongoing monitoring, meeting the standards that are needed for that, that is very often the remit of federal government and Environment Canada, and in my branch we're responsible for a lot of that.
Then research is something where research scientists will have an area of interest and they'll respond to where money is being given and what the newest science is. So ozone and/or a technology like LiDARs might be of interest this year and in three or four years not of interest.
LiDARs are of interest, but remain right now really a research technology. They're very expensive. They haven't developed to the point where you could apply them really for routine monitoring, as I understand them. The way we're using them and planning to use them in the oil sands is as an additional method to look at some of these air contaminants that we do have some concerns about.
