A bill that would make it illegal to wear a mask during a violent demonstration is nearing its final hurdle in the House of Commons, with just two hours of debate left.

Other notable private members business this week Wednesday: Second reading vote on Bill C-305, the National Public Transit Strategy Act, sponsored by NDP MP Olivia Chow and report stage vote on Bill C-350, the Accountability of Offenders Act, sponsored by Conservative MP Guy Lauzon. Thursday: Third reading debate on C-293, the Act to Amend the Corrections and Conditional Release Act (vexatious complainants), sponsored by Conservative MP Roxanne James. Friday: Second hour of debate on motion 312 to strike a special committee to look at when human life begins, moved by Conservative MP Stephen Woodworth.

Bill C-309 would make it a crime for people rioting or at an unlawful protest to conceal their identities. It's already illegal to wear a disguise when committing an indictable, or more serious, offence, which includes rioting. Unlawful protests, however, don't fall under that law because they're classified as a summary conviction, or less serious, offence.

An unlawful assembly is a gathering that causes fear. It's up to city officials to decide what constitutes a riot.

Last May, MPs on the House justice committee increased the penalty in the bill to 10 years for rioters who conceal their faces and five years for those at an unlawful protest. The maximum sentence for rioting is two years.

The committee sent the bill back to the House last May. Debate will resume Tuesday evening for an hour. MPs must vote on the changed bill before it can go on to the Senate to be studied in the Upper Chamber.

The second hour of debate is likely to be sometime in the next week, with a final vote at third reading expected at the end of October.

Blake Richards, the MP behind the bill, says he wanted to give police another tool to prosecute rioters and he was told the existing law was difficult to apply.

Earlier this year, the City of Montreal passed a bylaw to ban masks during protests. The move came amid massive student protests in Quebec over the then government's plan to allow universities to raise tuition fees.
