Quebec's chief electoral officer wants to take a closer look at fundraising in Transport Minister Julie Boulet's riding of Laviolette in the Mauricie region.

A formal investigation has been launched, after a preliminary review. Back in February, Boulet spoke in the national assembly, saying it was legal for companies to make political donations. In fact, only private individuals can make donations to political parties, and even then there is a $3,000 limit.

Boulet says that a verbal report from the staff of the chief electoral officer indicated her office had followed all the rules. CTV's John Grant reports that Boulet has no idea what is still under investigation.

Boulet is not the only cabinet minister whose fundraising is coming under scrutiny. The offices of junior transport minister Norm MacMillan and Education Minister Michelle Courchesne are also being looked at by Quebec's chief electoral officer.
