As diversity in Canadian schools continues to grow, it is essential to equip teacher candidates with effective strategies to support English language learners (ELLs) and international students. This chapter explores the crucial role of mentorship in teacher-education programs, preparing new educators to address diverse linguistic and cultural needs. Mentorship, defined as a professional relationship where experienced educators guide novice teachers, is examined in both one-on-one and group settings, promoting collaborative learning and reflection. The chapter emphasizes the development of key professional and soft skills, including empathy, cultural competence, effective communication, adaptability, and emotional intelligence, through targeted mentoring strategies: fostering cultural competence, providing nuanced and sustained feedback, modelling comprehensive support for diverse learners, modelling targeted language acquisition support, and maintaining professionalism while building trust. These strategies enhance both pedagogical skills and personal growth, fostering emotional resilience and reflective practice. A framework for effective mentorship programs is presented, supported by practical examples, demonstrating how mentorship empowers teacher candidates to build strong relationships with ELLs, navigate cultural barriers, and adapt instructional methods to meet diverse needs. By integrating research with practical insights, this chapter provides evidence-based strategies to provide mentorship that models culturally responsive and academically enriching environments for ELLs and international students, ultimately promoting equity and improving educational outcomes for all learners.
