From the CIC website: http://www.cic.gc.ca/english/information/applications/guides/3900ETOC.asp
'Any document that is not in English or French must be accompanied by:
the English or French translation; and
an affidavit from the person who completed the translation; and
a certified copy of the original document.'
If you use a translator who is a member of a provincial or territorial organization of translators and interpreters in Canada, the translator should know what to do. 'Translators who are certified members in good standing of one of the provincial or territorial organizations of translators and interpreters of Canada do not need to supply an affidavit.'
If your translator is not a member, then he or she should give you an affidavit: 'An affidavit is a document on which the translator has sworn, in the presence of a person authorized to administer oaths in the country in which the translator is living, that the contents of their translation are a true translation and representation of the contents of the original document.'
Certified true copies
'To have a photocopy of a document certified, an authorized person must compare the original document to the photocopy and must print the following on the photocopy:
“I certify that this is a true copy of the original document”,
the name of the original document,
the date of the certification,
his or her name,
his or her official position or title, and
his or her signature.
Who can certify copies?
Persons authorized to certify copies include the following:
In Canada:
a notary public
a commissioner of oaths
a commissioner of taking affidavits'
So basically you get a translation of the document into English or French. You put in the application the translation; a copy of the original that has been certified as a true copy by a notary public, a commissioner of oaths, or a commissioner of taking affidavits; and an affidavit from the translator. If the translator is a member of one of the translator and interpreter societies of Canada, you do not need an affidavit from him or her. (In addition, if it says on the form checklists that CIC wants the original, send the original, not a copy of the original. This would basically only be the police certificates in most cases.)
