Two Canadian soldiers were killed Sunday when their armoured vehicle rolled over in rough terrain near Kandahar City.
Military officials said the incident was "unrelated to enemy fire."
One of the killed soldiers has been identified as Cpl. Eric Labbe, 31, of the Royal 22nd Regiment. He was born in Rimouski, Que.
The identity of the second soldier is being withheld at the request of the family.
"We're saddened by this tragic loss. They will be missed and we will honour their sacrifice to the service of Canada and their contribution to bring peace to the people of Afghanistan," Brig.-Gen Guy Laroche told reporters in Afghanistan.
"On behalf of all the members of Joint Task Force Afghanistan, I would like to convey my most sincere sympathies to the families of our lost comrades."
CTV's Murray Oliver, reporting from Kandahar Airfield early Monday morning, said the accident happened at about 6:30 p.m. local time, about 40 kilometres southwest of the city in the Zhari district.
Both soldiers were travelling inside the turret of a LAV-3 as it journeyed along a dirt track made slippery by rain. They died on the scene.
Two other soldiers inside the vehicle were unhurt in the accident. They were driving to an area where they hoped to set up camp for the night.
"An investigation is underway to determine the exact circumstances of the incident," said Laroche.
The soldiers were part of operation Teng Azem, or "Steadfast Decision," an operation aimed at flushing out insurgents around the nearby community of Nalgham.
The operation has been underway since Friday and will likely continue, Oliver reported.
The deaths come one week after a roadside bomb blast claimed the life of Gunner Jonathan Dion, 27, as he travelled to Kandahar Airfield for New Year's Eve.
He was a member of the 5th Regiment d'Artillerie legere du Canada, which is based in Valcartier, Que.
Four other soldiers were injured in the attack.
Canada has 2,500 soldiers operating in southern Afghanistan as part of the NATO mission.
Since military operations began in 2002, 76 military personnel and one diplomat have died in the country.
