I think this is the section he was pointing you to:Link not working @legalfalcon
"Before foreign nationals who apply for a visa, permanent residency or file any other immigration application can be admitted into Canada, it has to be ensured that they would not present a risk to the safety or security of Canadians. All foreign nationals undergo a security screening, which is done primarily by partner agencies, such as CBSA and CSIS. You can read an in-depth article on security screening here. GCMS notes released by IRCC will redact the security-related information in the GCMS notes pursuant to section 15 / 16 of the Access to Information Act. If the security screening has not yet started the security field will reflect “not started” against it. However, if it is in progress or passed, it may show as blank and have s15/16 listed on the top right corner of the page."
