I may be partial, but Nova Scotia knows how to do it right. A compilation of birth, marriage and death records to the linked original scans. There are mistakes in transcriptions, so think of other ways you can spell a name, if you don’t find results the first time. As of January 2017: Births: 1864-1877, 1908-1915 (delayed registrations 1830-1915). Marriages: Bonds 1763-1864 Registrations 1864-1940. Deaths: 1864-1877, 1908-1965
City of Halifax 1890-1908.

I was searching for vital stats of Ontario and discovered that most, if not everything, listed for a price at ancestry.com is free on familysearch.org.
