Risks in Montreal
What is a major risk?
A major risk is the combination of the possibility of the occurrence of a hazard (flood, storm, ice, etc.) and how significant the consequences could be for vulnerable elements of the environment (the public, property, etc.) Hazard and vulnerability cannot define risk alone. For example, when 100 mm of ice paralyzed the greater Montreal area and Montérégie in January 1998, the consequences would not have been as disastrous in an uninhabited region of northern Québec. The consequences for vulnerable elements of the environment depend on the nature of the hazard and its intensity, but also the level of vulnerability of the exposed elements.
In many situations, the only way to reduce the impact of the hazard is to decrease the vulnerability of the public and property.
