We tend to assume that there is a lot of room for spontaneous adaptation. Hopefully the private sector and communities habituated to looking for their own self-interest will see the opportunities, as well as the dangers, and respond accordingly.
A role for government in this is to provide the best scientific information about climate change—its variability, trends, and future scenarios—and then engage the Canadian stakeholders, public and private, in an informed debate about what they can best do to respond to the risks and opportunities, and adapt accordingly.
Knowledge about the best way to adapt is not just scientific; it's the knowledge by the people in those sectors—those who are at risk or have the opportunity. As your question suggests, we need to generate a whole debate and a sense of the development of public policy as to how to encourage and facilitate people to go about this, which means removing the barriers and creating the opportunities.
