As you've described the process, the House of Commons finds itself in this awkward situation of being the host of the event at the request of the government, and without the capacity or tools to properly vet people. However, the former Speaker, Anthony Rota, actually said in his interview with CTV North Bay that normally lists go to the Prime Minister's Office, where they go through them with a fine-tooth comb, and then the invitation goes out from protocol, which seems to contradict the testimony you gave.
Who is more accurately describing what actually happens, Mr. Janse?
