Canadian lawmakers voted Tuesday to join the international coalition launching air strikes on the Islamic State of Iraq and Syria (ISIS) group in Iraq, Al Arabiya reported.
Parliamentarians led by Conservative Prime Minister Stephen Harper carried the vote, 157 to 134, in favor of the six-month mission.
Both the opposition New Democrats and Liberals voted against it, saying they fear the mission could become a quagmire.
Six hundred air crew and other personnel, along with six fighter jets and several other military aircraft, will now head to the Middle East.
Harper has ruled out sending ground combat troops.
But 69 special forces soldiers already on the ground will continue to advise security forces fighting the Islamic State group in the northern part of Iraq.
The White House welcomed Canada's decision.
"The United States welcomes the Canadian government's deployment of fighter and refueling aircraft, as well as intelligence, surveillance and reconnaissance aircraft to participate in the campaign to degrade and destroy ISIS in Iraq," a White House spokesman said.
"Canadians and Americans have fought alongside each other in several major conflicts over the past century, and we are grateful for Canada's further contribution against terrorism," the spokesman added.
ISIS gained international attention in August, when its fighters and those from other militant groups swept through the northern Iraqi city of Mosul, then overran swaths of territory north and west of Baghdad.
Western governments fear ISIS could eventually strike overseas, but their biggest worry for now is its gains in Iraq and the likely eventual return home of foreign fighters.
U.S. President Barack Obama last month outlined plans for a broad international coalition to defeat the group in Iraq and Syria.
The coalition, which includes Arab countries, intends to "significantly degrade the capabilities of ISIS, specifically its ability to engage in military movements of scale or to operate bases in the open," Harper said on Friday, using an alternate acronym for the group.
The military mission is supported by 64 percent of Canadians, according to a poll published by the daily Globe and Mail.
