This presentation discusses the use of digital technology for the teaching and research involving cultural and heritage materials in Canada-Hong Kong migration studies. I argue that the flow of people, ideas and materials between Canada and Hong Kong has been continuing in reciprocal directions. I conduct this research by using digitized artefacts, and online archives that has been curated for seamless, persistent and long-term access. I have studied the connections between the two locations from the perspectives of history, culture and literature, politics and democracy, economic and financial development and the network of people and community. In this lightning presentation, I illustrate the impact of technology on creating and curating materials for documenting the migration experiences for Hong Kong Diasporas using the three digital projects that I created, namely the Hong Kong Handover collection, the Hong Kong Basic Law Portal and the Hong Kong Political Movement Archive.
