| Abstract | The Geological Survey of Canada (GSC) has contributed earthquake hazard information for the National Building Code of Canada (NBCC) since the 1950s. The requirements for seismic hazard modelling and
mapping have changed over the years as scientists¿ understandings of earthquakes and their effects on buildings have evolved and improved. As the knowledge of, and sophistication in, probabilistic seismic hazard modelling techniques have advanced,
Canada¿s national mapping efforts have moved from qualitative assessment in 1953, to fully probabilistic for the hazard model proposed for the seismic provisions of the 2015 NBCC. The GSC now provides hazard models for the NBCC on a five-year cycle.

| Summary | (Plain Language Summary, not published)
The Geological Survey of Canada (GSC) is responsible for providing seismic hazard information to key stakeholders with the ultimate aim of safeguarding
Canadian citizens from the negative impacts of earthquakes. This contribution outlines the evolution of the national seismic hazard models in the context of the National Building Code of Canada (NBCC). The recently developed 5th generation national
hazard model is briefly described and intended to form the basis for the seismic provisions of the 2015 edition of the NBCC. Finally, the future needs of the national hazard model are discussed in terms of the key research priorities. These include:
sensitivity of hazard to various declustering algorithms; exploring the use of smoothed seismicity as an alternative earthquake occurrence model; the evaluation of modern GMMs; exploring risk-targeted hazard for the NBCC; and investigate the need to
consider hazard from induced seismicity. |
