Events of National Historic Significance (French: Les événements d'importance historique nationale) are events that have been designated by Canada's Minister of the Environment, on the advice of the Historic Sites and Monuments Board of Canada, as being defining actions, episodes, movements or experiences in Canadian history. To be designated, an event must have occurred at least 40 years ago; events that continue into the more recent past are evaluated on the basis of what occurred at least 40 years ago. As of September 2010, there are 417 designated Events of National Historic Significance.
Canada has related programs for the designation of National Historic Sites of Canada and Persons of National Historic Significance.
