I don't believe that the Government of Canada has an overall assessment of the costs of not adapting to climate change and the costs of adapting. The researchers would argue, and I've read studies, that not adapting is going to cost more than spending the money to adapt. However, because the Government of Canada has not done a good assessment of its risks across all of its assets, all of its programs, it does not have a good idea of the risks to government assets and programs, and delivery of programs to Canadians. If it doesn't have that, it can't have budgeted that. That has to be the first step.
