It is listed as a City of Toronto Heritage Property. In the 1970s, a land developer in London, Ontario used the characters from de la Roche's Jalna series to name streets for a new subdivision named "White Oaks". Streetnames used from the Jalna series include: Jalna Boulevard, Ernest Avenue, Renny Crescent, Finch Crescent, Nicholas Crescent, Alayne Crescent, Archer Crescent, Piers Crescent, Meg Drive. In 1990, a French-immersion public school in de la Roche's birthplace of Newmarket, Ontario was named in her honour. Responding to an enquiry on the pronunciation of her name, her secretary told "The Literary Digest": "Her Christian name is pronounced "may'zo", and Roche is pronounced "rosh", to rhyme with "Foch"."
