As far as I read our officials had problems with the punishment, not the crimes.

They were dual-cirizens. If they’re Chinese citizens and according to China’s legal system they had to go, how would it look in China if they don’t apply the rules because they were also Canadian citizens?

Flip it around, some Canadian citizens commit crimes that call for life in prison in Canada. Would we expect our courts to not sentence them because they also hold Chinese or some other citizenship?
