CTTIC was founded in 1970 and is the legal successor of the Society of Translators and Interpreters of Canada (STIC), which was incorporated in 1956.
It is now a federation of seven provincial bodies, one of which, the Association of Translators and Interpreters of Ontario (ATIO) is a founding member, along with the Ordre des traducteurs, terminologues et interprètes agréés du Québec (OTTIAQ).
Since 1972 they have been joined by the following organizations:
- Society of Translators and Interpreters of British Columbia (STIBC)
- Association of Translators and Interpreters of Alberta (ATIA)
- Association of Translators and Interpreters of Saskatchewan (ATIS)
- Association of Translators, Terminologists and Interpreters of Manitoba (ATIM)
- Corporation of Translators, Terminologists and Interpreters of New Brunswick (CTINB)
- Association of Translators and Interpreters of Nova Scotia (ATINS)
Following a decision made at CTTIC’s 2017 AGM, CTTIC withdrew from the International Federation of Translators (FIT) in 2018.
