I'll try my best to answer.
When we look at the amendment to clause 35, which is to expand the grounds of who can, in essence, request the commission's assistance, it is consistent with a change made earlier in the bill that this be expanded to third parties. It does not change the responsibility or the authorities of the commission to determine whether it wishes to investigate that complaint or whether that complaint meets the statutory threshold that exists elsewhere in the bill.
Expanding the class of persons who can bring the complaint doesn't change the process by which the commission itself, or the RCMP or CBSA, will make a determination, if it believes that the person has adequate standing, which could extend to consent or other grounds. It would, using its delegated authority in the statute, decide whether that third party has sufficient grounds to bring the complaint.
