A growing area of student mobility research points to the importance of examining regional differences in educational trajectories within Canada. Students from the northernmost parts of provinces often face significant proximity and socio-demographic barriers to attending postsecondary education, accessing various types of postsecondary education, and accessing many lucrative fields of study at the university level, such as the STEM fields (Science, Technology, Engineering, and Mathematics). This project explores regional differences in educational trajectories within Ontario. Building on the first phase of research utilizing Statistics Canada’s Postsecondary Student Information System (PSIS), this second phase explores graduation rates, access to STEM fields, and timely completion for transfer students in Northern and Southern Ontario.
