You will need the original documents + the original notarized translations. Once you have that, you’ll need to authenticate all the documents either at ODS in Toronto or Global Affairs in Ottawa. ODS only authenticates documents from Ontario; if your documents are from another country or another province other than Ontario you’ll need to authenticate them at Global Affairs in Ottawa.
Note: Global Affairs will not authenticate the wallet-size birth certificates; they will only authenticate original certificates issued by the Vital Statistics Office and that are signed by the Registrar. See this information:
* If your documents are not from Canada, the requirements are different. You’ll need your documents to be stamped by your country’s consulate/embassy, after that they’ll need to be authenticated at Global Affairs. If that’s not possible, your other option would be to authenticate your document in your country and legalize it in the Cuban consulate/embassy of that country. As long as your document has a stamp from the Cuban consulate it’ll be accepted in Cuba.
Once your documents are authenticated you can make an appointment at the consulate of Cuba in Toronto. You can contact them via email at toronto2@embacubacanada.net and send them a picture or scanned copy of all the documents already authenticated + a copy of your passport so they can review that your documents are ok. Then, they’ll get back to you with any questions or a date for an appointment. They charge $176 per each document in English and Spanish. So, if you have 2 English and 2 Spanish documents, your total would be $704. They accept payments via INTERACT debit card or money order or Canadian bank Certified Check made to “Consulate General of Cuba” or “Consulado General de Cuba”.
