Bill C‑377 would mean that members who so request would be able to follow the process provided to get a security clearance. There is a clear saving provision in the bill, to avoid weakening the privileges.
The purpose of the bill is neither to claim nor to create new privileges. It would therefore not allow members to get more rights to access information, but it would allow them to get the necessary security clearance for accessing the information the government might disclose to them. It would still be the government that made these decisions, because it is still information that belongs to the government.
