The government adopted a procedural manoeuvre on Wednesday intended to end debate over three disgraced Conservative senators.
Government Senate leader Claude Carignan intends to make a motion to suspend the trio.
Failing that, political turmoil over Senate expenses and allegations of a cover-up are expected to carry over from Parliament Hill to Calgary, where the Conservative national convention begins on Friday.
Prime Minister Stephen Harper, who has been implicated in the scandal through allegations made by Senator Mike Duffy, will address party members at the convention on Friday.
MP Cathy McLeod, who plans to attend, maintains that the underlying issue remains unchanged.
"That Nigel Wright paid back the money and that was wrong; that Nigel admitted it and has taken full responsibility; and the RCMP are investigating," she said. "I don't know that things have changed in terms of those facts."
McLeod avoided speculation on whether the controversy would dominate other matters on the convention floor.
"I certainly think there's going to be a lot of great conversation, lots of policy conversation, and conversation around accountability and transparency," she said.
Don Cameron, a former Tory MP who remains a party member, recognizes the difficulty that the issue poses at convention time.
"Going to a convention - I've gone to many - this is not a good thing," he said. "You want things in place and quiet. For the opposition parties, it's wonderful."
Cameron, 96, won't be attending the gathering, yet echoed the comments made by McLeod and Senator Nancy Greene Raine about the controversy, focusing on Senate accountability.
"I'm concerned about the money and there should be some controls," he said. "I hope they get to the bottom of it quickly."
He doesn't doubt that the scandal will have a negative impact on the party's fundraising capacity.
