I would add a couple extra points.
Back in the 1980s, the Mulroney government had a one-day prorogation. You can do something like that. You can have a one-day or a two-day prorogation. He didn't need six weeks.
The timing is absolutely important. You cannot divorce Bill Morneau's resignation from his implication in WE. Think of that committee meeting when he announced that he had written a cheque to WE Charity for $45,000 hours before testifying. That's pretty damning.
What happened after the prorogation? What was the coverage? It was about prorogation. It was less about Morneau's resignation for the ostensible reason of seeking this job at the OECD, which has quickly collapsed.
