Civic registration of births and deaths began again in 1908 but those records will not be publicly accessible before ca. 2008. They are not reasonably complete before about 1914. For more information, contact the Provincial Registrar of Vital Statistics. The Genealogical Society of Nova Scotia have published an index to Marriage bonds from 1763 to 1864. As the document was filed before the marriage, the existence of a bond is no guarantee that the ceremony actually took place.

These record local vital stats and other information of use to genealogists, especially for the period before the beginning of civil registration. Other provincial repositories often have copies of those pertaining to the local area and a few are available on microfilm from the National Archives of Canada and through the network of Family History Centres. Some of these have been published by GANS or other individuals or local organizations.
