Certified translation in Ontario, done right
Ontario is home to more newcomers, students, and internationally trained professionals than any other province, which makes certified translation part of daily life here. Whether you are filing an immigration application from Toronto, applying to a university in Ottawa, having foreign credentials assessed by a regulator, or submitting evidence to an Ontario court, the document that is not in English or French has to be translated and certified before it will be accepted. Certilingua handles exactly that, as a Canadian certified translation agency serving the whole of Ontario (ON) online.
In Ontario, a translation becomes official when it is produced by an accredited translator. The body responsible is the Association of Translators and Interpreters of Ontario (ATIO), the provincial association that grants the protected title of Certified Translator (C. Tr.). ATIO is a founding member of the Canadian Translators, Terminologists and Interpreters Council (CTTIC), the national council that sets common certification standards. When your translation carries the seal and signed declaration of an accredited ATIO translator, an Ontario institution reads it as the work of a qualified, accountable professional, which is why it is accepted without the back-and-forth that an uncertified translation can trigger.
As a certified translation company, our role is to bring that standard to you reliably. We coordinate a vetted network of accredited translators, match your document to the right professional in the right language pair, review the translation against the original, and certify it to the level your situation requires. The result is an official translation that is ready to submit, whether it is a single birth certificate or a full corporate file. For documents headed to a foreign authority or a court that asks for it, we can also provide a notarized translation with a sworn affidavit.
The needs across Ontario are varied, and so is our work. We translate civil status documents and police clearances for IRCC immigration and citizenship files, diplomas and transcripts for university admissions and credential assessments, professional licences for regulators and orders, and contracts and corporate records for businesses and law firms. Each comes with the same accredited, official standard, delivered on a timeline you can plan around, with express 24-hour service when an Ontario deadline will not move.
Choosing an accredited certified translation agency matters more than it first appears. Ontario institutions and immigration officers process a high volume of documents, and an uncertified or inconsistent translation is one of the most common reasons a file is delayed or sent back. An official translation from an accredited Ontario translator removes that risk, because the certification is a professional attestation backed by ATIO standards, not a claim. It is the difference between a document that clears review and one that sends you back to the start.
Certilingua brings more than two decades of focus to this work. We are a member of the Canadian Language Industry Association (CLIA) and the Globalization and Localization Association (GALA), and our translators hold accreditation through ATIO under the CTTIC framework. An established company, recognized memberships, and accredited translators together are what give an Ontario certified translation from us its authority, and what let individuals, students, professionals, businesses, and law firms across the province submit with confidence.
Who relies on certified translation in Ontario
The demand for official translation in Ontario comes from every direction. Newcomers and their families need certified translations of civil status documents, police clearances, and identity records for IRCC permanent residence, Express Entry, sponsorship, and citizenship applications. International students applying to Ontario universities and colleges need accredited translations of diplomas, transcripts, and proof of funds, often against tight admission deadlines. Internationally trained professionals, from physicians and nurses to engineers and accountants, need precise certified translations of credentials and licences so an Ontario regulator or professional order can assess them.
Organizations rely on us just as much. Ontario businesses translate contracts, financial statements, and corporate records as official documents for partners, banks, and authorities, while law firms across the province need court-ready certified and notarized translations that hold up as evidence. Whatever the document and whoever the reader, the standard is the same: an accredited, official translation from a translator certified in Ontario, prepared to be accepted the first time.

Ontario is one of the most multilingual places in the world, and our accredited translators reflect that.

Frequently Asked Questions
Do I need a certified translation in Ontario?
If you are submitting a document that is not in English or French to an Ontario institution, an immigration office, a court, a university, or a regulator, you almost always need a certified translation. It is the official standard these bodies rely on to accept a foreign-language document, and it confirms the translation is complete and faithful to the original. Submitting an uncertified version usually means the document is refused and has to be redone.
Who certifies translators in Ontario?
Translators in Ontario are certified by the ATIO, the provincial association that grants the Certified Translator (C. Tr.) title. ATIO is a founding member of the Canadian Translators, Terminologists and Interpreters Council (CTTIC), which sets the national standard for certification.
Is your certified translation accepted by IRCC and Ontario institutions?
Yes. Our certified translations are produced by accredited translators and are accepted by Immigration, Refugees and Citizenship Canada (IRCC), Ontario courts, universities and colleges, professional regulators, and employers across ON.
