Certified Translation of Documents: When documents are not in English or in French, the principal applicant must submit a copy of the original document and a copy of the certified translation. The Office of Immigration will only accept translations prepared by certified translators. Translators must be certified by a regulatory body and cannot be a family member of the applicant or spouse, or common-law partner, or work for a paid consultant or representative who is preparing the application. The applicant must also supply proof from the translator describing their translation ability or certification.
