Might some of the OICs have to do with Canadian aid to Ukraine or the financial measures against Russia/Russian citizens? Not all secrets are necessarily evil.
I will agree on that point, however, if they were very much things that would reach the news cycle anyway, why keep the Opposition and other Parliamentary committees in the dark?
The problem with democracy is that if it's to be maintained, it needs to transparent. Anything that blurs that transparency, even if necessary, blurs that transparency; and opens the door to further allowances.
In cases where "Yes this is something we don't want on Hansard because XYZ..", fine. You can have those with the proper clearance be kept in the loop, but off the mic about it. Making everything so secret that even those who are trusted to keep said secrets can't see it... that's not just protecting information; that's withholding the truth.
Our current government has played fast and loose with every imaginable rule we have to protect our democracy, to a degree that has rivaled the previous government they attacked for a lack of transparency. My spidey senses are tingling that this is more than just "Protecting Canada and Canadians."
