When a group declares its intentions to engage in combat with us, why should our response not include a military response, Alexander asks.
Murray responds by accusing the government of "undermining" the opposition parties for advocating a non-combat role.
We're back to NDP foreign affairs critic Paul Dewar. Asking for clarity from the Liberals: asking whether the Liberals believe that the House should have both a debate and a vote on a potential combat mission.
Murray says the Liberals have been clear, including looking for the best role for Canadians in the fight against ISIS.
Up now, Defence Minister Rob Nicholson. Comartin says he only has about seven minutes to speak before the debate breaks for daily question period.
If left unchecked, the threat posed by ISIS "will continue to grow," and further destabilize the security situation in the Middle East, Nicholson says.
"We must address this threat at its source," Nicholson says, after noting that ISIS poses a direct threat to Canada and its allies.
"Now is the time to act. We must help repel this threat before it unleashes a tidal wave of fundamentalist rule across the entire region," Nicholson says.
"This is a reasoned response, carefully considered" vis-a-vis Canada's duty to help, Nicholson says. "We must shoulder our share of the burden," he says.
Nicholson, like Baird, outlines the aircraft and personnel details of the current mission. No new details.
It's possible that there may be risk to our deployed (Canadian Forces) members, Nicholson acknowledges.
Nicholson appears rushed. Quickly flipping through the remainder of his speech to get it in within the seven-minute time frame the speaker gave him. Comartin says he has three minutes to continue after question period.
The debate has now paused for members' statements, to be followed by question period.
While MPs turn to question period, we will break here and return when the debate resumes in one hour.
Well, daily question period is winding down and MPs will soon turn back to their debate over the mission against ISIS.
We've got some government business to take care of before we get back to the debate.
And we get back to Defence Minister Rob Nicholson, who is told he has three minutes left to speak.
Canadian Forces members "will remain under the command of the chief of defence," Nicholson says. The opposition had questioned whether Canadian soldiers would fall under the command of an ally.
NDP defence critic Jack Harris is back up.
Harris asks if it has to be a military mission or bust? Nicholson responds that Canada has helped in other ways, including one million pounds of supplies to Iraq.
Marc Garneau is back up to ask whether Canada would proactively ask Assad if Canadian Forces could launch airstrikes in Syria, or just wait for Assad to approach the Canadian government. Nicholson does not directly answer the question, says Canada will act where it has authorization to do so.
Now, Green Party Leader Elizabeth May is up for the first time in this debate. Cites media reports that U.S. airstrikes are not pushing back ISIS militants in northern Iraq.
Nicholson says Canada is "doing what is reasonable under the circumstances" and says he's "disappointed" that Canada's actions don't have opposition support.\
Up now is Employment and Social Development Minister Jason Kenney.
Kenney quotes a UN report on ISIS's human rights abuses, including sexual assault, kidnappings, forced conversions, denial of humanitarian assistance, etc.
Iraqis, particularly religious minorities, are asking us to do what we can to help protect them, Kenney says.
The Iraqi government has requested Canada's assistance, and ordinary Iraqis have asked for this assistance, Kenney says.
Kenney quotes from letters he says have been written by Iraqi religious leaders, supporting the Canadian government's decision to launch a military mission against ISIS.
"There is an arc of violence held together by a common perversion of ideology," Kenney says of the terror groups inflicting violence around the world.
"The Iraqi government has not requested ground troops from Canada," Kenney says to question from Paul Dewar.
On the issue of humanitarian aid, Kenney says Canada has contributed $29 million, as well as an additional $10 million announced today. There will be more to come, he says.
Up again is Marc Garneau, asking again whether Canada would send CF-18s into Syria after asking permission from Bashar al Assad, or would we strictly wait for Assad to call up with a request.
Kenney responds that it's a hypothetical scenario not covered in the motion. Kenney then criticizes the Liberals for not supporting the motion, as well as Justin Trudeau's comment about whipping out our CF-18s and showing how big they are. "How profoundly un-serious," Kenney says of that quote.
Up now, a statement from Foreign Affairs critic Paul Dewar. The question before MPs is not whether Canada should do something. "We should," Dewar says. "We should, and our response should be serious and significant."
"The only ideology it supports is the ideology of hate," Dewar says of ISIS. The NDP is clear that "Canada has an important role to play in contributing to the international response to this crisis," he says.
Dewar says when he visited Iraq with Foreign Affairs Minister John Baird earlier this year, "nobody ever asked for fighter jets."
The federal government is sending Canadian Forces into war with a plan that is "so ill-defined it borders on irresponsible," Dewar says.
The motion allows the government to "go far beyond Iraq, and far beyond ISIL," Dewar says.
Dewar says the NDP has asked the federal government for four things: Support construction of refugee camps; help victims of sexual violence; help with international prosecutions of war crimes; and help protect religious sites.
Dewar then tells a story about a visit to a refugee camp in Iraq, and finding children playing. How can we best help them to grow up and thrive in a peaceful and prosperous Iraq? he asks.
