She became the first Canadian author to win a big international literary prize in 1927. She wrote the popular 16-volume Jalna series about a dynastic Ontario family.

By the time she died in 1961, 11 million copies of her books had sold in 93 languages. She lived at two Toronto addresses, possibly more: 86 Yorkville Ave. and 157 Dunn Ave. in Parkdale.

Mazo de la Roche is the subject of Back Lane Studios’ next Extraordinary Women event, presented in partnership with the Revue Cinema.

Filmmaker Maya Gallus will introduce her impressive documentary The Mystery of Mazo de la Roche, and discuss the author's life and work.

De la Roche carefully guarded her privacy, and much remains unknown, including the parentage of her two adopted children and the nature of her relationship with her lifelong companion and cousin, Caroline Clement. One thing is clear: Without Clement, De la Roche would not have become the prolific, successful author she did.

$15 general admission, $13 for seniors or Revue members at the door.

Tickets in advance for $13 on Eventbrite.

The Extraordinary Women series helps support Back Lane Studios' video and photography programs for students and seniors.
