Thank you for your quick and specific answer.
Holding public hearings means telling people that they are welcome if they want to come and discuss interference. Cherie Wong very recently said she wouldn't participate in public hearings. She's a member of the Canada Hong Kong Alliance and doesn't want to appear because she's afraid of reprisals.
That's the difference between a public hearing and an inquiry. An inquiry will summon people and be conducted in camera. It can summon people and request that documents be submitted to it. That way, people can safely go and speak with inquiry members and be examined and cross-examined. Information thus gathered would give us a clear idea of the kind of Chinese interference being carried on here.
Mr. Johnston, don't you think that's a promising approach?
