I think it's important to clarify that the July 20, 2021, intelligence assessment of CSIS was sent by CSIS to various points within the Government of Canada, including the Privy Council Office. That is my understanding of what happened. What exact points other than the Privy Council Office it went to is not clear.
I think it's also important to note that if one is to take the Prime Minister at his word, then clearly there was a breakdown in the machinery of government. In the government's “Open and accountable government” document, it's clear that the sole responsibility for the machinery of government is the Prime Minister's. It's also clear in that same foundational document that the Prime Minister is the lead on national security and has a special responsibility for national security.
Combining those two facts—that the Prime Minister has a special responsibility for national security and is alone responsible for the machinery of government—I think it's clear that the Prime Minister failed to structure the machinery of government in a way that would ensure information flowed to MPs and to the House of Commons when those MPs and the House were targets of foreign interference threat activities.
