The department said CF-18s hit artillery belonging to the Islamic State in Iraq and Syria, also known as ISIS or ISIL, using laser-guided munitions near Bayji, in northern Iraq. The Canadian Forces believed the equipment could have been used to attack coalition assets, the department said.
It is the second acknowledged strike by Canadian jets following the targeting of construction equipment near Fallujah, a militant stronghold about 71 kilometres west of Baghdad, on Nov. 2.
The CF-18 fighter jets arrived at a base in Kuwait on Oct. 30.
The latest strike involved a series of coalition forces.
"On this Remembrance Day, we reflect on the service and sacrifice of our veterans and serving members for their courageous dedication to our country," Defence Minister Rob Nicholson said in a statement. "I also commend the nearly 600 men and women in uniform for their tremendous work today in the international fight to degrade ISIL.
"This strike demonstrates Canada's firm resolve to tackle the threat of terrorism and stand with our allies against ISIL's atrocities against innocent women, children and men."
The department said it would provide further details on the strike later in the week.
