Note: Any documents that are not in English or French must be accompanied by:
the English or French translation; and

An affidavit is a document on which the translator has sworn, in the presence of a commissioner 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. 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. Translations by family members are not acceptable.
N.B.: Passport(s) and travel document(s) stamps that are not in English or French must also be translated.
