The big incident from the end of the Conservative convention was in the closing, when Senator Irving Gerstein took to the stage to boast about the party’s fiscal position, but in the process, revealed that he told Nigel Wright that he refused to allow the party fund – which he controls – to pay for Duffy’s expenses. This contradicts the Wright affidavit that said that they initially offered to pay the bill when they thought it was a mere $30,000 but balked when the bill was $92,000. Wright’s lawyer responded that they had nothing to say about “the latest characterisation of events” at this time – which has us all wondering which version of events is the truth. And more to the point, that if Gerstein was involved in the repayment scheme, even by refusing it, it begs the question as to why he’s not being hung out to dry like the others are. On Global’s The West Block on Sunday morning, Jason Kenney hinted that at some point, Wright will reveal what he knows, which could be very interesting if and when that happens – and if that timetable moves up should the PM continue to demonise him for the whole affair. As well, a PMO staffer says that the legal fees the party covered for Duffy were related to his audit.

Also from the Conservative convention in Calgary, Kady O’Malley rounds up the party constitution and policy resolutions that were agreed to before the plenary session, and the final outcomes somehow being characterised as a “shift to the right,” rather than an affirmation that this is a party on the right so motions about abortions and union-bashing shouldn’t surprise anyone. Laura Payton has four things that the delegates were talking about over the weekend, and not surprisingly, the current Senate woes weren’t really among them. Paul Wells gives his reading of the weekend and doesn’t see the Senate referendum in the future that others do – just a lot more economic populism. Colby Cosh ponders the hallucinogenic quality of party conventions. Andrew Coyne considers the convention as the party closing in on itself and cutting itself off of any distant early warnings of trouble.

The Supreme Court has upped the stakes in the Justice Nadon reference, and has effectively quarantined him until the reference is heard in January.

The RCMP are on the lookout for a letter that a staffer that Senator Wallin wrote to Senator Carolyn Stewart-Olsen, who was then on the Internal Economy committee, after Wallin fired her. Apparently this letter highlights some of Wallin’s questionable spending habits. Here’s a profile of the two Senate leaders that we keep hearing about with the proceedings there.

It seems that potential issues with the Sikorsky Cyclone helicopters were first flagged in 2004 when the then-Liberal government was shopping around, and their evaluators considered the risk “medium” because of things like a largely untested engine system. And yet they went ahead with it anyway.

A workplace harassment survey in the Canadian Forces shows that women, Aboriginals and visible minorities find themselves as the subject of more harassment – not that this should surprise anyone, really.

A high profile fundraising campaign for our war memorial in Vimy has been launched.

And Nathan Tidridge has a new book out about Prince Edward, Duke of Kent, who was father to Queen Victoria and who had a role in shaping Canada that most people don’t realise, including the first use of “Canadian” to the English-speaking population at the time when it was simply a reference to the French-speaking canadiens.

Up today: Expect to hear more from Senators Duffy and Brazeau in the lead up to the expected suspension vote on Tuesday.
