The OBPO believes that a more diverse workforce is better equipped to publish books by diverse authors, bringing more diverse stories to the Canadian public. Between 2018 and 2023, the OBPO, with the support of Ontario Creates, ran the Diverse Intern Initiative. In addition to providing financial assistance to publishers that allowed them to hire diverse paid interns, the OBPO offered professional development events focused on diversity, equity and inclusion. The OBPO continues to prioritise helping publishers employ, retain, and support a diverse workforce.
