There have been some precedents. There might be scenarios where, as part of a parliamentary function, there is a need to share classified government information. In those cases, the members of Parliament receiving the information would have to go through the process before receiving the information.
If there are, within each caucus, certain members who already have security clearances—because of their particular position, because of their role on specific committees, or maybe because they're more subject to foreign interference—and if there's a need to know, the government could share this information with those members without having them go through the process again, because they will already have received their security clearances.
