MyHeritage lists 417,794 births, 583,442 marriages, and 506,460 deaths in new database additions. All are freely available and are Crown copyright 2023, Province of Nova Scotia.
Compared to those available at https://archives.novascotia.ca/vital-statistics/, MyHeritage falls a bit short on births and is close to complete on marriages and deaths.
Direct access to available image originals saves the trouble of going to the separate Nova Scotia website.
