Operation Impact (Canadian contribution) was the official designation for Canada's multinational military contribution to the international campaign against the Islamic State of Iraq and the Levant and related stabilization efforts in Iraq and the region from 2014 onward. The initiative encompassed air operations, training, advising, intelligence sharing, and logistical support conducted by the Canadian Armed Forces in coordination with Operation Inherent Resolve, the Global Coalition to Counter Daesh, and regional partners such as Iraq, Kurdistan Regional Government, Jordan, and Kuwait. The deployment was shaped by successive Canadian governments and intersected with debates involving parliamentarians from Liberal Party of Canada, Conservative Party of Canada, and New Democratic Party.
Canada's intervention followed rapid territorial gains by Islamic State of Iraq and the Levant after the fall of Mosul and the declaration of a caliphate in 2014, prompting international responses led by United States Department of Defense and coordinated through United Kingdom Ministry of Defence efforts. The stated objectives included degrading Islamic State of Iraq and the Levant military capabilities, preventing attacks against Canada and its allies, and supporting stabilization and governance in liberated areas such as Ramadi and Tikrit. Decision-making drew on intelligence from National Defence of Canada agencies, assessments by the Department of National Defence (Canada), and allied consultations with NATO and the Arab League.
Initial deployments under the Harper administration included CF-18 McDonnell Douglas CF-18 Hornet fighter jets, CP-140 Aurora surveillance aircraft, and refuelling tankers from the Royal Canadian Air Force, alongside maritime patrol contributions via the Royal Canadian Navy. Ground contributions shifted under Trudeau to a training mission based at the Erbil area, involving instructors from the Canadian Army and elements of Canadian Special Operations Forces Command. Participating units worked alongside contingents from the United States Armed Forces, United Kingdom Armed Forces, France, Australia, and regional forces including the Iraqi Army, Peshmerga, and Popular Mobilization Forces.
Canadian CF-18 sorties executed air interdiction, close air support, and reconnaissance missions in coordination with Combined Joint Task Force – Operation Inherent Resolve command structures and coalition air wings. Notable coalition operations in which Canadian elements contributed intelligence or support included the Battle of Sinjar, Second Battle of Tikrit, and the Siege of Mosul (2016–17), though Canadian pilots did not participate in every assault. Maritime and surveillance assets contributed to operations against ISIL logistics networks and foreign fighter movements linked to incidents like the 2015 Paris attacks deterrence efforts.
Following parliamentary decisions, Canada transitioned to a training, advising, and capacity-building role focused on the Iraqi Army and other local forces. Training occurred at Camp Taji, facilities in Erbil, and partner bases in Jordan and Kuwait, covering infantry tactics, improvised explosive device mitigation, medical care, and logistics. Canadian training teams coordinated with advisors from the United States Army Training and Doctrine Command, Australian Defence Force, and the United Kingdom Ministry of Defence to enhance interoperability with coalition partners and assist the Iraqi Security Forces in planning operations such as the Battle of Mosul (2016–17).
Parliamentary debates in Ottawa reflected partisan divisions: the Harper ministry authorized air strikes and support, while the Trudeau ministry re-evaluated mandates and shifted emphasis to training, prompting motions in the House of Commons of Canada. Civil society groups including Amnesty International and Canadian Centre for Policy Alternatives scrutinized rules of engagement and humanitarian impacts, and veterans' organizations such as the Royal Canadian Legion engaged in policy discussions. Public opinion polls during the period showed fluctuating support influenced by events like the 2014 Sinjar crisis and the 2015 Paris attacks.
Operation casualties for Canadian Forces were limited relative to some coalition partners, with non-combat fatalities and several combat-related incidents among personnel, plus isolated friendly-fire and aircraft incidents in the region. Financial analyses by the Parliamentary Budget Officer and the Department of National Defence (Canada) reported multi-year expenditures encompassing operations, equipment deployment, and training programs. The broader campaign contributed to the territorial dismantling of Islamic State of Iraq and the Levant control over cities such as Mosul and Raqqa, though post-conflict governance and reconstruction challenges persisted in areas including Anbar Governorate and Nineveh Governorate.
Post-deployment assessments by the Office of the Auditor General of Canada, parliamentary committees, and allied think tanks such as the Canadian Global Affairs Institute and International Crisis Group examined the mission's strategic effectiveness, force posture, and lessons for expeditionary operations. Evaluations stressed the value of intelligence-sharing with National Defence partners, capacity-building with the Iraqi Security Forces, and interoperability with NATO and coalition partners, while also highlighting challenges in stabilization, civilian protection, and long-term reconstruction tied to treaties and agreements in the region. Operation Impact influenced subsequent Canadian defence policy debates on expeditionary readiness, force structure, and commitments to multinational coalitions such as Operation Inherent Resolve and future stabilization missions.
