The report is framed around three broad questions: 1. What do we know now about equity of postsecondary access in Ontario and what are the key data sources that contribute to that understanding? 2. What do we need to know in order to design policies and programs that effectively address access‐related issues? 3. What are the relevant criteria for effective data infrastructure and models to which Ontario can look in order to expand policy‐relevant knowledge about equity of access? This project was based on 35 in‐depth interviews with leading researchers, institutional stakeholders, and policy actors, as well as an extensive literature review.
