Given the rise and diversification of the immigrant student population within Canadian school systems, the establishment of policies that support immigrant pupils' transition and integration has become of pressing concern for policymakers. Following our multi-dimensional support model, this study examined the extent to which Ontario's provincial education policies, guidelines, and strategies respond to the needs of immigrant students within the K-12 public education system. For the most part, the current analysis indicated that the ministry has established the necessary educational support measures to integrate immigrant students. However, our findings also suggest that this group of students warrants a stand-alone policy document to comprehensively address all of their unique needs. Moreover, this study underscores the importance of greater policy coherence and direction within Ontario, as well as the ongoing role that evidenced-based research should serve in the development and refinement of existing policies.
