And so does the political gamesmanship as all parties try to downplay past blemishes and gain the upper hand in the race to be seen as the champion of transparency in the eyes of the voting public.
Who's willing to disclose all? Who's got something to hide? Who's trying to have it both ways?
As the one-upmanship unfolds, CBC Politics blogger Kady O'Malley hosts her weekly people's caucus to take your comments and questions about the ongoing expenses controversies in both the Commons and the Senate.
- Will tomorrow's Senate board of internal economy committee meeting with the audit team from Deloitte become public? How confident are you that Auditor General Michael Ferguson's involvement will help sort out the fundamental issues on Senate expenses?
- If MPs have nothing to hide, why did the Commons not unanimously adopt Trudeau's motions about disclosing House expenses and making its board of internal economy proceedings more transparent?
- What do you make of recent Elections Canada expense file revelations: not only the case against two Manitoba MPs who some feel should be suspended, but also this week's disclosure of parliamentary secretary Eve Adams' tastes?
Plus: What do you make of Harper's transparency announcement for the resource sector today in London? Has Canada been transparent enough about what's happening at the table with its EU trade talks?
