A few weeks ago, the Ministry of Foreign Affairs spokesperson expressed that they may bar Hong Kong people from departing from Hong Kong.
Also, many of the high-profile social activists, such as Mr. Martin Lee, who is considered to be the father of democracy in Hong Kong, and even Jimmy Lai, as well as Joshua Wong, etc., have had their passports confiscated by police in Hong Kong. There is no way for them to be able to get out of Hong Kong unless there is collaboration among like-minded allies to provide a special tunnel to Hong Kong for them to get out, just like what happened right after the Tiananmen massacre in 1989.
When a lot of those social activists from mainland China arrived in Hong Kong, through a collaboration among different embassies in Hong Kong, they managed to get out of Hong Kong. I think this is one way Canada can consider. Collaboration with other allies in Hong Kong is of utmost importance.
The other possibility is that I think before anyone's passport is going to be confiscated, it is also important for us to offer them the safe harbour program so that they can also get out of Hong Kong as soon as possible. If they wish, they can stay here, at least temporarily, or even seek residency.
