Prism Linguistics provides Thai interpreters and certified Thai translation across Canada. Thai is a tonal language written in its own alphabet and is the national language of Thailand, and the community here, built largely through family sponsorship, study and business ties, is concentrated in the Greater Toronto Area and Metro Vancouver. Work spans IRCC files, medical and court settings, and civil-document translation nationwide.

Thai is tonal and its written form runs together without spaces between words, but the more practical point for interpreting is register: everyday Thai, polite Thai and the formal royal vocabulary differ, and a court or IRCC setting calls for a careful, complete rendering rather than a casual summary. Standard central Thai serves most work, though we note when a speaker uses a strong regional form such as Isan in the northeast or a southern variety, so an interpreter can follow it accurately.
Across Canada, Thai interpreting is arranged for IRCC interviews and family-sponsorship matters, hospital and clinic appointments under PHIPA and PIPEDA, courts and tribunals, and business meetings. On-site attendance is realistic in the Toronto and Vancouver areas, and telephone or video interpreting reaches speakers anywhere else in the country; consecutive interpreting suits interviews and clinical visits where each turn must be rendered faithfully.
Common settings include legal and court interpreting, medical and hospital interpreting, IRCC and Immigration and Refugee Board (IRB) interviews, and police and enforcement work. See all on-site interpreting options or start a free quote.
Certified Thai translation works from the Thai script, and two features need attention. Thai official dates use the Buddhist Era, which is 543 years ahead of the common calendar, so we convert and note dates carefully, and Thai personal names are often long and are transliterated to match the passport spelling. We deliver a complete English or French translation with a signed Certificate of Translation Accuracy, or a sworn affidavit before a commissioner of oaths where required.
The papers we handle most are the Thai national identity card, the house registration record known as tabien baan, birth, marriage and divorce certificates, the official name-change records that are common in Thailand, and education transcripts and police clearances for permanent residence and provincial licensing. Where a person's name has changed we note each version so a reviewing officer can follow one individual across a file, and acceptance ultimately depends on the receiving institution.
For documents rather than spoken interpreting, see certified Thai translation, our full Thai translation services, or general document translation. Every translation moves through our TEP workflow — translation, editing and proofreading by separate linguists — with free revisions.

Thai is the official language of Thailand, with around 60 million native speakers and another 20 million using it as a second language. The Thai community in Canada is modest but well established, concentrated in Toronto, Vancouver, and Montreal, anchored in part by the Thai restaurant and hospitality industry. Translation work is split between civil documents -- Thai birth certificates, marriage records, and household-registration papers for IRCC applications and sponsorship -- and business content tied to hospitality and trade. Thai is tonal with five tones and uses its own script, an abugida derived from Old Khmer.
