First, you should find "admissibilities" section (goes after general information about the application data, in my case it starts on page 29). In this section of CBSA notes, you will see "security" activities, and, probably, "security screening" subactivity. In my case, there is smth like this inside of it:
security screening type (A34): comprehensive
# of people sent for screening: 1
I'm not an expert, but I think this is a sort of evidence that I'm under comprehensive SS
