Our research focuses on the role of Greek HL school principals in Canada, highlighting their impact in shaping the schools’ vision, encouraging language heritage use, and securing resources to sustain the Greek programs. Principals, acting as cultural liaisons, seek to cultivate meaningful relationships with families and communities, support teachers by providing them with professional development opportunities, while also striving to fulfill their administrative responsibilities. In addition, school leaders have a crucial role in ensuring that the school environment enables students to develop their language skills, cultural awareness, and sense of belonging. An important area of investigation within the Hellenic Relay is, therefore, how principals perceive and address institutional, pedagogical, and cultural challenges at the school context. Research data processing, based on questionnaires and interviews, revealed that principals tend to operate as agents of continuity and sociocultural change reinforcing linguistic and cultural maintenance in the diaspora.
