The Canadian All Hazards Risk Assessment (AHRA) has been developed as a result of the government’s acknowledgement that there is an increase in natural and man-made threats and lessons learnt from domestic and international events which could also affect developed nations such as Canada. This chapter discusses the approach to emergency management in Canada and the governance framework in the risk assessment process which revolves around the concept of an all hazards approach with the objective of assessing and viewing risks in a standardised approach using a common set of principles and steps. While the AHRA methodology is published, transparency and accountability does not extend to full publication of the identified risk profile due to national security concerns. The introduction of legislation dictates specific roles and responsibilities to a lead ministry and specific ministries with responsibility for their own sector. This is discussed in the chapter as a core element for a standardised risk assessment methodology leading to effective multi-level governance and multi-actor participation.
