CanIL began with a simple conviction: that Canada should train its own for the worldwide work of Bible translation. In 1985, at the invitation of Wycliffe Bible Translators of Canada, the Canada Summer Institute of Linguistics opened at Trinity Western University in Langley — then a small university with, as the story goes, scarcely a linguistics book in its library. The Wycliffe veteran George Cowan got that first summer running, and a handful of students came.

The early years were lean; one summer the whole program numbered ten. But the founders — led by Mike Walrod, who directed CanIL through its first decades — believed the need was real, and they went looking for students in churches, colleges, and universities across the country. In 1991 they set a marker: if thirty students enrolled for the summer, they would take it as the sign to grow beyond a single season. The thirtieth registered on the last office day before classes began.

Growth followed. Advanced courses began in the fall of 1992, spring courses in 1994, and by 1995 CanIL taught year-round — so "Summer" no longer fit the name, and the Canada Summer Institute of Linguistics became the Canada Institute of Linguistics. In 1999, CanIL incorporated and formed its own board of directors.

By the early 2000s the program had outgrown its borrowed rooms. CanIL launched a campaign to build a home of its own on the Trinity Western campus, and in 2003 — after what many who were there remember as a string of remarkable provisions — broke ground. Classes began in the new Harvest Centre in the summer of 2004, and on July 11, 2005 — the first anniversary of its grand opening — the 32,000-square-foot building was announced completely paid off, built debt-free through donated funds, labour, and materials.

That same instinct — that money should not stand between a person and this calling — shaped how CanIL came to treat its students. Through bursaries, scholarships, matching grants, and paid work experience, many graduates now finish their training debt-free and ready for the field.

The degrees matured alongside the partnerships: a bachelor's in linguistics in the late 1990s, and the MA in Linguistics with Trinity Western in 2006. In the fall of 2015, CanIL's training grew eastward, taught alongside Tyndale University in Toronto. In 2020, it began offering the Master of Arts in Translation of Scripture with Northwest Seminary. Today CanIL trains alongside Trinity Western and Northwest Seminary in Langley and Tyndale University in Toronto, as a member of SIL Global, with faculty who carry over 350 years of combined field experience among minoritized language communities worldwide.

More recently, the work has widened. CanIL has taken on the long-term development of TBTA and TaBiThA — more than twenty years of computational-linguistic research that helps translators safeguard the meaning of the source as they work — and established a new department, Language Services and Research, to steward it. Beyond Bible translation, the department also serves First Nations language preservation and revitalization here in Canada: the same craft, turned toward the languages of this land.

Forty years on, the calling is the same as it was that first summer — to help every language, and everyone who speaks it, flourish.
