Politicians in Quebec City want to talk to the men in charge of one of the province's largest retirement funds, which happens to be run by Quebec's largest union.

Quebec Federation of Labour president Michel Arsenault, along with the director of the union's investment fund Fonds de solidarité-FTQ Yvon Bolduc, have been ordered to appear before the standing committee on public finances on Nov. 5.

The move comes after the Parti Quebecois voted against a CAQ motion to have the fund's directors appear before a parliamentary committee, arguing that would have too broad a mandate.

The QFL and its investment arm have been under scrutiny for several years, ever since former QFL executive Ken Pereira went public with allegations of wrongdoing by top executives.

In recent testimony before the Charbonneau Commission Pereira accused top QFL executives of collaborating with organized crime, and said suspected or known gangster's bragged about having control of the Fonds de solidarité-FTQ.

This year the federal government has also eliminated a 15 percent bonus tax break given to investors in the fund.
