Yes. Again, I'll start by talking a little bit about our work in the area of oil spills, and Carol can comment and add any details on the specific amounts in supplementary (B)s.
This is an area where we're doing a fair amount of work at the moment. From the Environment Canada angle, it comes in two forms. When there is an oil spill, often we're not the lead department in that exercise. It could be Transport or another department that would be leading. We are very important in a couple of regards, one of which is that we provide a coordination effort in terms of the response to an emergency, whatever it might be, such as an environmental emergency. We are putting a lot of effort into making sure we are doing that effectively. We've got some greater efficiencies in that area now, and we're able to better manage when something happens, making sure everybody knows what's going on.
I would also add that we contribute with our weather services in terms of the need to track wind patterns or anything that would help determine what the impacts of the spill would be and what the next steps would be. We provide efforts on that front.
The other area, in terms of oil spills, is that we are doing some scientific research on how diluted bitumen behaves, for example, in water. Does it behave the same as other types of oil? Are there things we can see that would help us know about the behaviour? This is if there were to be a spill. We do everything we can to prevent there ever being one. So we contribute on that science side of things to the debate to try to bring that scientific information to the front.
Those are a couple of the areas where we contribute to the oil spills regime. I think Environment Canada plays a pretty significant role.
Carol, if you want to talk a little bit about subsidies—
