Given how bumbling and third-rate many Canadian institutions are today, I would generally doubt the Canadian government's ability to assess anything like this competently.

I'm also not confident in our government's ability to prevent full-on Chinese state actors from tampering with such an assessment.

Added: though this should not be taken as a reason to defer to the U.S. government either. Our institutions regularly fail to serve their purposes, and the first step to solving that is to actually care that it's the case.
