Children’s heritage language maintenance and development is a challenging issue that many immigrant parents have to face nowadays. Despite the multitude of Chinese immigrants overseas, Chinese as a heritage language often fails to be effectively sustained and suffi ciently developed inter-generationally due to pervasive language shift and language loss in Chinese immigrant families. Previous research focusing on Chinese families’ heritage language and bilingual/biliteracy education tends to privilege studies on single cases, resulting in a gap in the existing literature of an integrated perspective on how heritage language acquisition and education take place in the home milieu of Chinese immigrant families. Based on the qualitative data collected from Chinese immigrant families residing in different geographical regions in Canada, the authors developed a continuum development model to horizontally compare and analyze the dynamics of family language policies across different families. Four representative families are purposefully selected for a further discussion on the potential factors behind the formation of particular types of family language policies. Framed within the the oretical construct of family language policy, this paper aims to provide a new conceptual perspective towards immigrant family language policy development and minority language protection within the multilingual, macro social context of the host society.
