- Applicants from outside Ontario may use any translator, but the translation must be notarized.
Customers looking for certified translation in Ontario often encounter the term ATIO-certified translator. For many private and federal uses, the receiving institution's own rules determine what is acceptable. For the Ontario Immigrant Nominee Program, however, Ontario publishes specific translation requirements.
What is ATIO?
ATIO is the Association of Translators and Interpreters of Ontario. Its public directory allows users to search for certified translators by language direction.
Language direction matters. Certification in Arabic to English, for example, should not automatically be treated as certification in English to Arabic unless both directions are held.
What does OINP require?
Ontario's current OINP guidance says that supporting documents not in English or French must be accompanied by a copy of the original and a complete certified or notarized translation.
For applicants applying from within Ontario, translations must generally be completed by an ATIO-certified translator. If an appropriate ATIO-certified translator cannot be located, Ontario provides an exception requiring a notarized translation plus a letter explaining why the translation is not certified and evidence of efforts to locate an appropriate ATIO-certified translator.
For applicants applying from outside Ontario, the translation can be completed by any translator but must be notarized. Ontario also reserves the right to require an ATIO-certified translation if the notarized translation is considered unacceptable.
Certified translation across Ontario
Certified translation demand is not limited to Toronto. Customers in Ottawa, Mississauga, Brampton, Hamilton, London, Windsor, Kitchener-Waterloo, Vaughan, Markham, Richmond Hill and other Ontario communities may need certified document translation.
Where electronic workflows are permitted, the translator and customer do not necessarily need to be in the same city. What matters is the translator's appropriate certification, language direction, availability and the receiving institution's format requirements.

ATIO maintains a public certified translator directory.
