Canada's critical infrastructure - the physical and cybernetic elements on which we rely to operate most modern services and systems - may be facing excessively high levels of risk from both natural disasters and human error or malice. The dispersed nature of this infrastructure heightens our vulnerability. Dealing with this unique threat in advance requires that we understand its nature, and, once the real risks are identified, that we implement a cohesive, sustainable approach led by the federal government. Because the problem includes so many stakeholders, the federal government needs at the very least to develop a culture that increases the level of information shared among them and encourages communities of practice to mitigate potential disasters.
