I'd be happy to give a much more textured response.
The main reason for the increases is the representation of new priorities on the part of the government in the area of natural resources. Some of the examples include the increase that accounts for the investments in the forest industry long-term competitiveness strategy and the investments in offshore development to which the minister made reference in terms of the investments we're making in research and development to substantiate our claims under the UN Convention on the Law of the Sea.
We have investments, of course, in the mountain pine beetle that are reflected in that increase. We have investments in nuclear waste legacy liabilities, which were announced in 2006, as well as increases in the low-level radioactive waste clean-up at Port Hope. We have additional investments that reflect the costs for the relocation of our CANMET laboratories, which will be relocated to a new innovation cluster at McMaster University. Also, there are overall investments in the clean air agenda, which are represented through the ecoENERGY investments.
