Today on the Hill: More grist for the electoral reform mill expected

OTTAWA - Proposed changes to Canada's election laws will remain in the spotlight on Parliament Hill today on three fronts.

Besides the anticipated questions in the House of Commons that are being asked daily of late, the government will hear from Yves Cote, the commissioner of Elections Canada, when he appears at a Senate committee studying Bill C-23.

Cote will be followed by Harry Neufeld, the former chief electoral officer for Elections B.C., and others.

A Commons committee that's studying the controversial bill will also hear from a number of witnesses.

"On Wednesday, Liberal Leader Justin Trudeau vowed to repeal the proposed changes if he becomes prime minister, but also called on Stephen Harper to allow a free vote on the bill."

Here are some other events happening today around Parliament Hill:
