As far as Justin Trudeau goes, unless a development has been made that I'm unaware of, two Canadians are being held in China against their will right now. Likely in a cell with the lights turned on 24 hours a day.
They've been held captive since Dec. 10, 2018. 337 days of torture. Canadians can call China's ambassador to Canada
to release them by dialing 613 789 3434, Ext 0. There is a third Canadain being held as well who was sentenced to death on a drug charge. There may be more. I am aware of these three. This all has to deal with Canada holding Meng, the Huawei woman who the US wants to prosecute.
I have called that number a few times. I'm not sure what good it does anymore but I do think about them.
Trudeau needs to go to China and not leave until the Canadians are released.
