The federal Conservatives want MPs to create an anti-corruption committee to investigate the WE Charity issue.
Tory ethics critic Michael Barrett says the new forum would press for answers to lingering questions about the controversy.
In the meantime, the Conservatives plan to press the House of Commons ethics and finance committees this week to resume looking at the matter.
They say the proposed new anti-corruption committee could soon take over the probe of the Liberal government's choice of WE Charity to administer the the multimillion-dollar Canada Student Service Grant program.
Opposition MPs have been grilling the government for months over the now-abandoned program because of WE Charity's close connections to the families of Prime Minister Justin Trudeau and Bill Morneau, the recently departed finance minister.
The Liberals have consistently said it was federal public servants who recommended the grant program be administered by the youth group, but the Conservatives say there are still unanswered questions.
