London sits at the heart of southwestern Ontario, a regional hub of about 422,000 people anchored by Western University, Fanshawe College, and one of the largest hospital networks in the province. It has drawn newcomers for decades, and the result is a city where a growing Arabic-speaking community lives alongside long-established Spanish, Mandarin, Portuguese, and Polish speakers. That mix creates steady demand for accurate document translation and trained interpreters, whether the matter is an immigration application, a hearing at the courthouse on Dundas Street, a hospital appointment, or a foreign degree being assessed for admission or licensing. This page explains how certified translation and interpreting work in London, what IRCC and the Ontario courts actually require, which languages matter most locally, and how to arrange the right service when the provider does not need to be next door.
Key takeaways
- Certified translation in London, Ontario means a translation carrying the seal, signature, and membership number of a translator certified by a recognized professional body, most often the Association of Translators and Interpreters of Ontario (ATIO). IRCC accepts these without a separate affidavit.
- ATIO is the provincial association for Ontario, and the certification examination its members pass is set by the Canadian Translators, Terminologists and Interpreters Council (CTTIC), the national umbrella body. Certified Translator is a title reserved by Ontario law.
- According to the 2021 Census, the most common non-official mother tongues in London are Arabic at 3.7 per cent, Spanish at 2.7 per cent, Mandarin at 1.6 per cent, Portuguese at 1.3 per cent, and Polish at 1.1 per cent, which shapes the languages most often requested locally.
- The London Courthouse at 80 Dundas Street houses the Superior Court of Justice and the Ontario Court of Justice for civil, criminal, family, and small claims matters, and French language services are available there.
- Professional Interpreting Canada serves London remotely by secure video and phone and on site through interpreters dispatched from the Toronto and Hamilton area, covering medical, legal and court, conference, and immigration settings.

What Does Certified Translation in London Actually Mean?
People in London often use the phrase certified translation loosely, but it carries a precise meaning the moment a government office, court, or university reviews your file. A certified translation is a translation completed by a professional translator who is a member in good standing of a recognized translators association, who attaches a signed statement of accuracy and stamps the document with a seal showing their name and membership number. The certification ties a named, accountable professional to the accuracy of the work, which is exactly what an official reviewer is looking for.
In Ontario, the body that grants this status is the Association of Translators and Interpreters of Ontario. ATIO is the oldest organization of translators, conference interpreters, court interpreters, and terminologists in Canada, and in February 1989 the Province of Ontario granted reserved title to its certified members through the Association of Translators and Interpreters Act, 1989. That made ATIO the first translators association in the world whose certified members are recognized as professionals by law. The certification examination itself is controlled by the Canadian Translators, Terminologists and Interpreters Council, the national council of which ATIO is a founding member, and administered provincially by ATIO. Only members who have passed that examination and subscribed to the code of ethics may call themselves a Certified Translator, and translations bearing their stamp in the relevant language pair are accepted by most federal and provincial departments without any further certification by a notary or commissioner.
This is the standard we work to. Our translators are certified members of recognized associations, and you can read more about how that qualification is earned and verified on our page about ATIO certified translation. If you are weighing whether you need a certified translation or a notarized one, the distinction is set out in detail in our guide to the difference between certified and notarized translation in Canada.
Why London Generates Steady Demand for Translation and Interpreting
London is not a border city or a bilingual capital, but several features of its economy and population keep a steady stream of language work flowing through the city, and they explain why certified translation and qualified interpreting are needed here as much as in any larger centre.
A major university and college town
London is home to Western University and Fanshawe College, two institutions that together enrol tens of thousands of students, including a large international contingent. Fanshawe in particular became one of the country’s biggest recipients of international study permits in recent years before federal caps reduced those numbers. International students routinely need academic transcripts, diplomas, and supporting civil documents translated and certified, both to gain admission and later to apply for post-graduation work permits or permanent residence. The presence of these institutions alone keeps academic and immigration translation in steady demand across the city.
A regional health-care and research centre
London is the medical hub of southwestern Ontario. The London Health Sciences Centre is the city’s largest single employer, and the wider network of hospitals, clinics, and research institutes draws patients and families from across the region. Many of those patients do not speak English as a first language, and a trained medical interpreter is what allows a safe, accurate appointment to happen. Health care is one of the settings where interpreting demand in London is most reliable and most consequential.
A genuinely multilingual and growing population
London grew by ten per cent between the 2016 and 2021 censuses, faster than many comparable Ontario cities, and much of that growth came from immigration. Statistics Canada’s 2021 Census language data shows that beyond English, the leading mother tongues in the city are Arabic, Spanish, Mandarin, Portuguese, and Polish, alongside established Korean, Punjabi, Malayalam, and Urdu speaking communities. These are precisely the languages that turn up most often in our London caseload, whether for translating civil-status documents or interpreting at a clinic, a settlement agency, a school, or a hearing.
Certified Document Translation for IRCC and Immigration in London
For many people in London, the first time certified translation becomes urgent is an immigration or citizenship application. IRCC is clear about what it expects, and getting it right the first time avoids the most common cause of delay: documents returned because the translation does not meet the rules.
If a supporting document is not in English or French, IRCC requires a translation. Where the translation is done by a translator certified in Canada, meaning a member in good standing of a provincial or territorial association such as ATIO, the certified translator seals or stamps the document and no affidavit is needed. Where the translation is done by someone who is not certified, IRCC requires an affidavit. As IRCC’s guidance on translating documents explains, an affidavit for a translation is a document in which the translator swears, in front of a commissioner authorized to administer oaths in the country where they live, that the translation is a true and accurate representation of the original. There is also a firm restriction worth knowing: the translation cannot be done by the applicant, by a family member, or by an immigration representative, even if that person happens to be a qualified translator.
Using a certified translator from the outset is the simpler route, because it removes the notary step entirely. The documents we are most often asked to translate for London immigration files include the following.
- Birth, marriage, divorce, and death certificates
- Police and security clearance certificates
- Academic diplomas, degrees, and transcripts for study permits and credential assessment
- Employment records, reference letters, and professional licences
- Passports, national identity cards, and family registration documents
- Bank statements, proof of funds, and other financial records
Our dedicated walkthrough on how to get documents translated for IRCC sets out the certified versus affidavit choice step by step, and our document translation service handles the full range of personal and corporate paperwork. For the overall picture of certified work and the professionals behind it, see our page on certified interpreters and translators.
A quick comparison: certified translator versus affidavit route
| Consideration | Certified translator (e.g. ATIO member) | Non-certified translator plus affidavit |
|---|---|---|
| What proves accuracy | Seal, signature, and membership number on the translation | Affidavit sworn before a commissioner for oaths |
| Extra notary step | Not required | Required, in person before an authorized official |
| Accepted by IRCC | Yes, as a certified translation | Yes, when the affidavit accompanies it |
| Who may not do it | The applicant, a family member, or their representative | The applicant, a family member, or their representative |
| Typical turnaround impact | Faster, fewer moving parts | Slower, depends on notary availability |
Translating Foreign Degrees and Credentials in a University City
Because London is built around Western University and Fanshawe College, credential translation is a recurring need here in a way it is not everywhere. International applicants need their foreign transcripts and diplomas rendered into English before an admissions office or a credential assessment service will evaluate them, and internationally trained professionals applying for licensure in fields such as nursing, engineering, or teaching face the same requirement. The translation must be complete and faithful, reproducing grades, course titles, seals, and signatures, because the assessing body compares the document against recognized standards.
A certified translation gives those bodies the accountable, professionally sealed document they expect. We translate academic records for university and college admission, for assessment by services such as World Education Services, and for professional regulators. Our guide to foreign credential and degree translation in Canada explains how this works in practice and what assessing organizations look for, so you can prepare the right package before you submit.
Court and Legal Interpreting in London
London’s main courthouse sits at 80 Dundas Street, in the downtown core, and houses the Superior Court of Justice for civil, family, criminal, and small claims matters, with the Ontario Court of Justice also sitting in the building. The Government of Ontario, which sets out how court interpreters are arranged in the province, notes that French language services are available at this location over the phone and at the counter, reflecting the reality that proceedings sometimes run in French, and often in a third language when a party or witness needs one.
Legal interpreting is a specialized discipline, not simply bilingual conversation. A court interpreter must render testimony precisely, preserve register and tone, handle legal terminology accurately, and remain strictly neutral, because a misrendered phrase can affect a person’s rights or the outcome of a case. The right to the assistance of an interpreter in a proceeding is guaranteed by section 14 of the Canadian Charter of Rights and Freedoms. The same rigour applies to depositions, examinations for discovery, tribunal hearings, immigration and refugee proceedings, sworn statements, and lawyer-client meetings. Our work with the courts and the standards interpreters are held to are described in our overview of court interpreters, which explains the role in the Ontario justice system, and you can read more broadly about why qualifications matter in our piece on the importance of a certified interpreter.
For London legal matters we provide interpreters by secure video and telephone for remote hearings and client meetings, and we arrange on-site interpreters for proceedings where physical presence is required, subject to availability and notice. Law firms in the city also frequently need certified translation of evidence, foreign judgments, contracts, and corporate records, which we handle alongside the interpreting through our legal document translation services.
Medical Interpreting in London
Health care is one of the highest-stakes settings for interpreting, because the cost of a misunderstanding can be a wrong diagnosis, a missed symptom, or a consent form a patient did not truly understand. London’s hospitals, clinics, community health centres, and mental-health services see patients from every linguistic community in the region, and a trained medical interpreter is the difference between a safe appointment and a risky one. A professional interpreter conveys not only the words but the clinical meaning, manages sensitive and emotional content with care, and observes the confidentiality that medical work demands.
Relying on a bilingual family member, or on a member of staff who happens to speak the language, is widely discouraged in health care for good reason. Family members may soften bad news, omit details, or lack the clinical vocabulary to interpret accurately, and asking a child to interpret for a parent is never appropriate. Professional medical interpreting removes those risks. Our experience in this area is set out on our medical interpreter page, and although it is framed around Toronto, the same trained interpreters and the same standards serve London clients by video, by phone, and on site.
Video remote interpreting has become especially useful in London health care. It connects a qualified interpreter to a clinic or a telehealth appointment within minutes, which matters when a patient who speaks Arabic, Mandarin, or Spanish arrives without notice. For longer, more sensitive, or more complex appointments, an on-site interpreter is often the better choice, and we will advise honestly on which fits your situation. You can read more about how remote delivery works on our page about video remote interpreting in Canada.
Conference and Business Interpreting in London
London hosts academic symposia, association conferences, medical and research gatherings, and corporate meetings, many of which bring together participants who do not all share a language. This is the natural home of simultaneous interpreting, the mode in which interpreters render a speaker’s words in near real time so the audience hears the message in their own language with only a few seconds of delay. Western University and the city’s research institutes in particular generate events where international delegates need full language access.
Because simultaneous interpreting is cognitively demanding, interpreters work in pairs and switch every 20 to 30 minutes, supported by booths, consoles, and audience receivers for in-person events, or by remote simultaneous interpreting platforms for online and hybrid ones. Planning the language channels, the equipment, and the interpreter team in advance is what keeps quality high. Our conference interpretation service manages that end to end, and if you want to understand when simultaneous mode is appropriate versus consecutive, our explainer on the difference between consecutive and simultaneous interpreting lays it out clearly.
Which Languages Does London Need Most?
London’s language profile reflects decades of immigration to southwestern Ontario. English is the mother tongue of just over 71 per cent of residents, and the leading non-official languages, drawn from the 2021 Census, line up closely with what we see in day-to-day requests. The table below summarizes the picture.
| Language | Share of London residents (2021 mother tongue) | Common service needs |
|---|---|---|
| Arabic | About 3.7 per cent, the largest non-official mother tongue | Immigration documents, medical and settlement interpreting |
| Spanish | About 2.7 per cent | Civil-status document translation, legal and community interpreting |
| Mandarin | About 1.6 per cent | Academic and immigration translation, business interpreting |
| Portuguese | About 1.3 per cent | Civil documents, community and family interpreting |
| Polish | About 1.1 per cent | Civil-status translation, legal and notarial documents |
| Korean, Punjabi, Malayalam, Urdu | Each around 0.7 to 0.8 per cent | Healthcare, academic, and immigration interpreting and translation |
We work in more than 500 languages in total, including many that rarely appear in a single city’s top ten but still come up in immigration, medical, and legal contexts. Our full range is listed on our languages page. If you do not see your language there, it is still worth asking, because our network is wider than any list.
How Professional Interpreting Canada Serves London
We will be straightforward about how we operate, because honesty about logistics is part of doing this work well. Professional Interpreting Canada is based in the Toronto and Hamilton area, and we serve London in two complementary ways.
The first is remote service. For document translation, nothing needs to happen in person at all. You send us scans or photographs of your documents, our certified translators complete the work, and we return the certified translation electronically and, where you need them, by mail. For interpreting, secure video remote interpreting and telephone interpreting let a qualified interpreter join a London appointment, hearing, or meeting from wherever they are, often at short notice and in a wide range of languages. Remote delivery is frequently the fastest and most flexible option, and for many London clients it is all they need.
The second is on-site service. When a matter calls for an interpreter physically in the room, for a long or sensitive hearing, a complex medical procedure, or an in-person conference, we arrange on-site interpreters dispatched to London, subject to availability and adequate notice. Because on-site work in another city involves scheduling and travel, it benefits from more lead time than a remote booking, so the earlier you contact us, the better the match and the timing.
To be clear, we do not operate a walk-in storefront in London, and we will never pretend otherwise. What we offer is certified, accountable translation and qualified interpreting delivered to London by the means that suits your matter. The single phone number for all enquiries is (647) 558-5843, and every quote request is answered within 24 to 48 hours.
Nearby coverage across Ontario
London sits within the broader southwestern Ontario market we serve daily. Clients with operations or family matters spanning more than one city often need the same certified translation and interpreting in several places, and we provide a consistent standard across all of them. Alongside London, we regularly support clients in Toronto and the surrounding region, in Hamilton, and in Kitchener and Waterloo, with the same certified translators and the same interpreter network. You can see those city services on our pages for certified translation in Toronto, court interpreters in Hamilton, and interpreter services in Kitchener. Closer to London along the Highway 401 corridor, we also serve clients needing certified translation in Windsor and certified translation in Brampton.
How to Arrange Certified Translation or Interpreting in London
Getting started is simple, and the more detail you provide up front, the faster and more accurate our quote will be.
- Tell us what you need. Specify whether it is document translation, interpreting, or both, and for translation, name the documents and the source and target languages.
- Describe the purpose. An IRCC application, a court proceeding, a medical appointment, a credential assessment, and a conference each have different requirements. Knowing the purpose lets us apply the right certification and the right expertise.
- Share the details. For translation, send clear scans or photos of every page, including stamps and seals, which must also be translated. For interpreting, tell us the date, expected length, number of participants, languages, and whether you need remote or on-site service.
- Choose the mode for interpreting. Most appointments and interviews use consecutive interpreting; conferences and large events use simultaneous interpreting. If you are unsure, we will recommend the right approach.
- Request your quote. Send everything through our get a quote page or call (647) 558-5843. We respond within 24 to 48 hours with a clear quote rather than a guess, because price depends on language, length, document type, certification, mode, and notice.
We do not publish fixed prices, because a one-page birth certificate and a fifty-page set of corporate records are not the same job, and an hour of remote phone interpreting is not the same as a full day of on-site conference work. What we promise is a transparent quote and certified, professional results.
Frequently Asked Questions
What is a certified translation in London, Ontario?
A certified translation in London is a translation completed by a professional translator who is a member in good standing of a recognized body such as the Association of Translators and Interpreters of Ontario. The translator attaches a signed declaration of accuracy and a seal showing their name and membership number. Translations bearing the stamp of an ATIO Certified Translator are accepted by most federal and provincial departments, including IRCC, without an additional affidavit.
Does IRCC accept translations done outside London?
Yes. IRCC’s requirement is about the translator’s qualifications, not their physical location. A translation completed by a translator certified in Canada, who seals or stamps the document, is accepted regardless of where in the country the translator is based. This is why our remote certified translation service works perfectly well for London clients: the certification travels with the document, not with a local address.
Do I need an affidavit if my translator is certified?
No. According to IRCC, if your translation is done by a translator certified in Canada, the certified translator’s seal or stamp is sufficient and no affidavit is required. An affidavit, sworn before a commissioner authorized to administer oaths, is only needed when the translation is done by someone who is not a certified translator. Using a certified translator therefore removes the notary step.
Can a family member translate my documents for a London immigration application?
No. IRCC does not allow translations to be completed by the applicant, by a family member, or by an immigration representative, even if that person is a qualified translator. The translation must come from an independent translator. This rule protects the integrity of the application, and it is one of the most common reasons documents are returned, so it is worth getting right from the start.
Can you translate academic transcripts for Western University or Fanshawe College?
Yes. We translate foreign transcripts, diplomas, and degree certificates for admission to institutions such as Western University and Fanshawe College, for assessment by credential evaluation services, and for professional licensing bodies. The translation reproduces grades, course titles, seals, and signatures faithfully, and it carries the certification that admissions and assessment offices expect. Send us clear scans of every page and tell us the institution or assessor it is for.
Which languages are most in demand in London?
According to the 2021 Census, the leading non-official mother tongues in London are Arabic, which is the most common at about 3.7 per cent, followed by Spanish at 2.7 per cent, Mandarin at 1.6 per cent, Portuguese at 1.3 per cent, and Polish at 1.1 per cent. The city also has established Korean, Punjabi, Malayalam, and Urdu speaking communities. We work in more than 500 languages in total, so even less common languages can usually be arranged with adequate notice.
How do I get a court interpreter for the London courthouse?
The London Courthouse at 80 Dundas Street administers court proceedings for the Superior Court of Justice and the Ontario Court of Justice, and French language services are available there over the phone and at the counter. For private legal needs such as depositions, examinations for discovery, tribunal hearings, sworn statements, and lawyer-client meetings, we supply qualified legal interpreters by video and phone, and on site by arrangement. Tell us the language, the type of proceeding, and the date, and we will match an interpreter with the right experience.
How much does certified translation or interpreting cost in London?
There is no single price, because cost depends on the language pair, the length and type of document, whether certification is required, and for interpreting on the mode, duration, number of participants, and whether the work is remote or on site. Rather than quote a misleading flat rate, we provide a clear, itemized quote once we understand your needs. Send the details through our get a quote page or call (647) 558-5843, and we respond within 24 to 48 hours.
Do you have an office in London, Ontario?
We do not operate a walk-in office in London. Professional Interpreting Canada is based in the Toronto and Hamilton area and serves London remotely by secure video and telephone and on site through interpreters dispatched to the city, subject to availability and notice. For certified document translation, no in-person visit is needed at all, because documents are handled electronically and returned with the certification attached.
