The Canadian educational documents (diplomas, certificates, transcripts and letters) can not be used out of Canada unless they are signed and stamped by the principal/Vise principal or a relevant office of the registrar (The name of the person signing must figure on the document that needs the authentication and legalization ) as a first step and afterwards the next steps are the notarization by the notary public ,authentication by DFAIT and legalization by the embassy.
We, Imperial Legalization & Visa, are dealing with these academic credentials (diplomas, certificates, transcripts…) in our daily basis for their notarization, Apostille/authentication and legalization.
