On 23 October, MPs in the House of Commons gave a standing ovation to Vickers for his heroism. As Mulcair of the New Democratic Party put it: "Just as we have all borne witness to these horrific acts, we have watched in awe your acts of courage, now an abiding emblem of Canadian strength, values and valour." Prior to the day's session, Harper laid a wreath at the War Memorial; MPs from all parties attended a moment of silence and sang "
O Canada" at the Memorial before walking together to Parliament. Over the following days, several NHL teams held moments of silence and "O Canada" was sung prior to games in the United States in which no Canadian team was participating. On 25 October,
pre-game ceremonies were jointly held in Ottawa, Montreal, and Toronto to honour the deceased and first responders. On the same day of the attack, before an NHL game between the
Pittsburgh Penguins and the
Philadelphia Flyers, the
Canadian National Anthem was sung in honour of the attack. The largest Canadian flag was used for a pre-game ceremony between the
Ottawa Redblacks and the
Montreal Alouettes of the
CFL. A fund to benefit the families of Cirillo and Vincent was started on 22 October with a goal of CDN$10,000. It surpassed its goal by noon the following day, when representatives of Canadian banks called to arrange a donation of $80,000. By 29 October, the fund, known as the
Stand On Guard Fund, had raised $550,000. The fund raised $705,000 of a newly-set $750,000 goal by the time the fund-raising deadline was reached. A mosque in
Cold Lake, Alberta, was defaced overnight with graffiti. This was immediately cleaned up in a joint effort with local residents. An Ottawa mosque was the scene of two incidents: A member praised the attacker as a martyr after prayers, leading to the police stopping him for national security reasons the next day. A vandal then destroyed several windows, causing over $10,000 in damages. As soon as the war memorial was reopened to the public, a makeshift memorial to Cirillo grew in front of it; residents laid out flowers, cards, and wreaths. On 24 October 2014, Cirillo's body was transported home to Hamilton in an official motorcade along
Ontario Highway 401, the portion of which between
Trenton and Toronto is known as the
Highway of Heroes. The times of the motorcade were publicized and people stood at overpasses to observe and as it passed. Cirillo's family released a statement and gave thanks to the Canadian Forces for the support offered and to those who came to the soldier's aid. Thousands attended visitation at the funeral home where Cirillo
lay in repose. He was accorded the honour of a full regimental funeral service and funeral procession on 28 October in Hamilton, attended by family, soldiers, and dignitaries. On 27 October, a concert by the
National Arts Centre Orchestra (NAC Orchestra) (from Ottawa) and
Royal Philharmonic Orchestra (from London) concert was dedicated to Patrice Vincent and Nathan Cirillo and was attended by
Prince Charles. The NAC Orchestra dedicated its entire UK tour of five performances to Vincent and Cirillo. On 11 November, the annual
Remembrance Day service at the war memorial was held as planned. It was attended by
Anne, Princess Royal, along with the Governor General, the Prime Minister, and other dignitaries. It was attended by a larger than normal crowd of 50,000. This was attributed to "a rising tide of concern for Canada's Forces" since the attacks. There was an increased police presence at the event because of the two killings and military
armored vehicles patrolled the area, while military personnel were deployed on nearby rooftops. Other Canadian politicians and
social media also reacted.
Elizabeth II, the
Queen of Canada, issued a statement from her and
Prince Philip, Duke of Edinburgh, expressing shock and sadness. Her federal representative,
Governor General David Johnston, extended his sympathies to the family of the deceased Canadian soldier and gratitude for the "professionalism and courage of our security personnel and emergency responders." In a televised address that evening, Harper called the shootings a "brutal and violent attack"
Justin Trudeau, the leader of the
Liberal Party of Canada, said "Canadians know acts such as these committed in the name of Islam are an aberration of [the Muslim] faith. Mutual respect and admiration will help to prevent the influence of distorted ideological propaganda posing as religion." A public statement by the
Muslim Association of Canada condemned the violence in Ottawa and Quebec: "MAC would like to offer its condolences to the victims of violence over the past week. We are horrified by these acts of violence, especially in the Parliament of our nation's capital. We stand with all Canadians in condemning these attacks and seeking justice for those responsible." The National Council of Canadian Muslims also said it: "stands united with Canadians in categorically condemning today's shooting attacks." A national poll by the Angus Reid organization released on November 25, 2014, revealed that Canadians in general were also split as well on whether the attack and shooting was an act of terrorism or mental illness. 38% felt that it was the result of mental illness, while 36% felt it was terrorism, with 25% undecided. Asked about what the federal government should do as a result, 54% felt that more initiatives should be done to prevent radicalization, while 34% favoured harsher punishments. On how to deal with homegrown terrorists, 54% felt that indefinite incarceration only motivated persons to commit crimes, while 46% felt it prevented violent crime.
American President
Barack Obama was briefed about the attacks. The
White House released a statement that read: "President Obama condemned these outrageous attacks, and reaffirmed the close friendship and alliance between our people." Greenwald's opinion was in turn criticized by academic
Daniel W. Drezner who said that his argument was both banal and incomplete, and that the reason why there was shock in Canada at the attack was that democracies at least claimed to adhere to jus in bello when they prosecuted violent conflicts, whereas some of their opponents did not.
British Prime Minister
David Cameron said he was "appalled by [the] attack in Ottawa" and offered his full support to his Canadian and Commonwealth counterpart, Stephen Harper, and the Canadian people as they dealt with the incident. An editorial in
The Economist from 8 November 2014, in discussing the impact on US-Canada border security, said: The attack in Ottawa last month by a lone gunman, who killed a Canadian soldier and stormed parliament, seems likely to make matters worse. Although there is still uncertainty about the motives of the gunman, Michael Zehaf-Bibeau—possibly a deranged outcast, possibly a religious extremist—the United States is reviewing security along the 5,525-mile (8,890km) line which separates the two countries (including the Alaskan land border).
