First of all, I hope the Canadian government at all levels communicates, for example, Environment Canada and Health Canada and their jurisdictions. More collaboration makes for more data sharing and often, to do any computation you need data. Many times, this data is obtained but because they are under different jurisdictions, the data are not maximized or integrated or treated properly. Putting more data in the larger public domain is the first thing that should be done.
There are different types of modelling and assessment. Risk assessments are computationally much simpler. You have different data, and this is not to be unkind. It's just from a mathematical process, it's simpler.
When we talk about, for example, air pollution or climate modelling, we're talking about the models they have, which all run based on the conservation of mass and energy. You have chemical reactions of various types. You have physical processes. You have radiation and so forth, that can run online, meaning numerically you can calculate all of them for this set-up for the different grids that we discuss, sub-units of calculation, that can be integrated.
We are normally geeks and we integrate the data that way, but for many of the other data that is used for policy, you use a dumber, slightly less sophisticated—
