In the larger context of migration, the education and integration of immigrant children within Canadian school systems has become a pressing concern for education policy makers. Through a systematic content analysis, this study developed a Multidimensional Support Model to examine education policies and support measures that have been articulated by Ministries and Departments of Education across Canada to facilitate the integration and success of immigrant students in K–12 public education systems. The discussion underscores the timeliness and rationale for Ministries and Departments of Education to develop a stand-alone policy document to address all of the unique needs of immigrant students comprehensively and devote greater attention to the socio-economic challenges immigrant students disproportionately face. Developing this document would also address the importance of greater policy coherence and collaboration among ministry sectors. The utility of the proposed support model, which drew on the existing literature, is also discussed in relation to future research studies.
