## Early life and Canadian beginnings
Cariou was born in St. Boniface, Manitoba in 1939 and grew up in Winnipeg, where his father George Marius worked as a salesman and his mother Molly Estelle (née Moore) raised the family.[1](https://www.canadiantheatre.com/dict.pl?term=Cariou%2C+Len) • [4](https://www.encyclopedia.com/education/news-wires-white-papers-and-books/cariou-len-1939) He studied singing as a child, and by grade 10 he was directing and starring in school plays at Miles MacDonnell Collegiate, where his theatrical debut came as Ralph Rackstraw in *HMS Pinafore*.[1](https://www.canadiantheatre.com/dict.pl?term=Cariou%2C+Len)
His first professional performance was in *Damn Yankees* at Winnipeg's Rainbow Stage in 1959, the start of a theatrical career that would run through roughly 85 stage productions.[1](https://www.canadiantheatre.com/dict.pl?term=Cariou%2C+Len) • [8](https://www.yahoo.com/entertainment/meet-actor-len-cariou-glimpse-150217423.html) He then played multiple roles at the Manitoba Theatre Centre, where he was a founding member, including Eilif in *Mother Courage* with Zoe Caldwell (directed by John Hirsch) and Nick in *Who's Afraid of Virginia Woolf?* opposite Kate Reid.[1](https://www.canadiantheatre.com/dict.pl?term=Cariou%2C+Len) From 1962 to 1965 he played supporting roles at the [Stratford Festival](https://www.edgepedia.org/stratford-festival).[1](https://www.canadiantheatre.com/dict.pl?term=Cariou%2C+Len)
John Hirsch, the Hungarian-born refugee who became a leading Canadian director, proved the decisive mentor: Cariou credited Hirsch with hiring him for Rainbow Stage and, without his knowledge, arranging his move to the Shakespeare Festival in Ontario.[9](https://www.tdf.org/on-stage/tdf-stages/len-cariou-on-just-about-everything/)
## Stage career on Broadway and in the classics
