MPs will start off the week with a significant vote in the House of Commons: to extend Canada's mission against ISIS by one year and expand airstrikes to Syria.

The vote on the government's motion to extend and expand the mission is expected Monday night. While the opposition parties have expressed their intention to oppose the motion, the Conservative majority is expected to easily pass it.

After the motion passes, the next major question will be when Canadian planes can expect to start bombing ISIS targets in Syria. That date has not yet been released by the government. 

Here's how the rest of the week in Ottawa is shaping up. It will be a busy one.

Monday

Prime Minister Stephen Harper will make an announcement Monday afternoon at the Honda plant in Alliston, Ont., speaking alongside Trade Minister Ed Holder and Minister of Labour and Status of Women Kellie Leitch. 

Defence Minister Jason Kenney will be joined by Lt-Gen. Yvan Blondin in Trenton, Ont., Monday for a tour of Canada's newest CC-177 Globemaster cargo plane. Kenney will take questions from the media.

Veterans Affairs Minister Erin O’Toole will also be on the announcement circuit tomorrow in Ottawa. According to a news statement issuedSunday, O’Toole’s announcement will “benefit Canadian Armed Forces personnel, veterans and their families.” A story from The Canadian Press, quoting unnamed sources, says O’Toole will announce targeted improvements to bring lump sum awards for the most severely disabled veterans more in line with what courts award civilians injured in workplace accidents.Before it's even done review at the House of Commons level, the government's anti-terror bill will head to the Senate national defence committee with a hard-hitting roster of witnesses: Public Safety Minister Steven Blaney, Justice Minister Peter MacKay, RCMP Commissioner Bob Paulson and CSIS Director Michel Coulombe. 

And back on the Commons side, Chief of Defence Staff Gen. Tom Lawson will appear before the defence committee on the "Defence of North America." 

The Subcommittee on a Code of Conduct for Members will also meet in camera to deal with the issue of harassment complaints between MPs. The meeting comes on the heels of a harassment scandal that saw two MPs expelled from the Liberal caucus in November. 

Tuesday 

Tuesday marks the deadline for 68 NDP MPs to pay back $2.75 million in taxpayer dollars used to staff so-called satellite party offices. Last month, the multi-party Board of Internal Economy (BOIE) ordered the MPs to pay back the money.

It remains unclear how the BOIE will deal with the repayments after the Tuesday deadline. According to the BOIE bylaws, the board has the authority to request reimbursement from MPs. But the NDP Leader Thomas Mulcair recently told CTV's Question Period that he doesn't expect the board to actually garnish any wages, as the party has asked taken its fight to the Federal Court. 

Some NDP MPs owe around $1,000, while others face six-figure bills. For instance, Montreal MPs Alexandre Boulerice and Isabelle Morin will be asked to repay $120,000 and $170,000 respectively, while Leader Thomas Mulcair and party whip Nycole Turmel owe more than $600,000 combined. 

Also on Tuesday, the House of Commons public safety committee will consider government and opposition amendments to Bill C-51, the government's controversial anti-terror bill. 

CTV News has learned details of some of the government's amendments, including the removal of the word "lawful" from a portion of the bill that deals with protests that could be targeted. The goal of the amendment would be to limit the scope of what could be considered a terror-related activity. Another amendment will also make it clear that CSIS officers do not have the power to make arrests. 

The opposition parties have been calling for additional oversight of Canada's security agencies. It remains to be seen whether the Conservatives will consider this in the clause-by-clause review of the bill Tuesday.

And finally, Privacy Commissioner Daniel Therrien will appear before the Commons finance committee to discuss terrorist financing in Canada and abroad. 

Thursday 

Suspended Senator Patrick Brazeau's trial for sexual assault and assault charges will continue Thursday. The alleging victim, whose identity is protected by a publication ban, will appear.
