Short answer - probably not! In Ontario only licensed Officiants, some city clerks and Justices of the Peace are able to legally marry people. BUT ... we're happy to perform the legal aspects of a ceremony either during, before or after a ceremony performed by someone who is not licensed!
Marriage licences are good for three months and we generally recommend that you don't leave it until the last minute, especially if either party has been divorced or is not a Canadian citizen.
NO!!! And you won't get any notification from the government that they've registered your marriage and they don't automatically send a certificate, YOU HAVE TO APPLY YOURSELVES 6-12 WEEKS AFTER YOUR WEDDING!
Marriage licences are issued by municipalities, and you can get married anywhere. You can download the application at ontario.ca then you bring it in with ID and any other documentation (e.g. divorce decree). The cost varies by municipality but is usually around $150.
At the wedding your Officiant will complete the licence and the marriage register (kept by the Officiant) and you'll be given the Record of Solemnisation from the second page of the licence. The signed licence is the legal record of your marriage and the Officiant is responsible for sending it to the Registrar General for Ontario.
There are only three parts of a marriage ceremony which are legally required - Statement of Intent, Witness Affirmation and Declaration of Marriage. Everything else is personal choice including ring exchange, vows, readings,, hand fasting, candle and unity ceremonies, etc.
