I think, first and foremost, Canada needs to look at expanding its lifeboat scheme for Hong Kongers, particularly for young Hong Kongers who are not graduates and who need a lifeline out of the city and do not qualify for the U.K.'s BNO visa scheme. That should be first and foremost.
Second of all, the Canadian government needs to closely monitor what's happening with the immigration bill and make sure that if there is a restriction of freedom of movement out of the city, it's ready to go beyond sanctions, working with the U.S., U.K. and European partners.
The U.S. restricted trade to the Soviet Union because it restricted freedom of movement in the cold war. It's something similar to consider if China decided to restrict freedom of movement out of the city of Hong Kong.
