Documents in another language often need a certified translation. Here is what that means, and when a sworn affidavit is needed.

Government offices, courts and immigration authorities often need documents in English or French. A document in another language usually needs a certified translation.
Use a certified translator (for example, a member of the Association of Translators and Interpreters of Ontario). If a certified translator isn't available, many authorities accept a translation with an affidavit of translation sworn by the translator.

In Ontario, certified translators are members in good standing of ATIO (or another Canadian provincial association). Their translations carry their stamp or seal.
When a non-certified translator is used, they may need to swear an affidavit before a commissioner or notary, confirming the translation is accurate and that they are fluent in both languages.
IRCC requires translations of documents not in English or French, together with a copy of the original. If the translator isn't certified, an affidavit is usually needed. Family members of the applicant generally can't do the translation.
Courts have their own rules for translated documents; check before filing.
Keep originals safe and provide copies, certified if needed.
