Managing cultural differences between international students and host university members is a significant challenge for international student office (ISO) staff at Ontario universities. The current influx of incoming international students to the province of Ontario continues to stretch ISOs' limited resources and support functions. This study focused on understanding these Ontario universities' international student offices and their strategic initiatives to remedy the existing challenge of assisting international students more effectively. This qualitative study applied the case study approach for its collection and analysis of data from several data sources: staff member interviews, public documents, and notes taken during field visits. The study found that the international student offices functioned as coordinating units to work with other appropriate offices to provide services to their international students while they shared their expertise with other units. The study also found the international student offices extended their coordination functions to external entities.
