This article introduces and discusses the findings of the Canada School Choice Policy Index (CSCPI). This is the first index of its kind that measures the development of school choice policies across the Canadian provinces from 1980 to 2020 using eight unique indicators of choice. In contrast to other countries in the Organisation for Economic Co-operation and Development (OECD), the CSCPI reveals that although Canada has witnessed an increase in school choice over time, this increase has largely been contained within public education systems rather than in the expansion of private education options. Our findings raise the importance of future research to address growing choice in public education systems across the provinces, in addition to choice in the private sphere.
