A flag-draped coffin carrying the body of Master Corporal Byron Greff made a sad trip down the Highway of Heroes Tuesday, as Canada welcomed its latest fallen soldier home from Afghanistan.

MCpl. Greff arrived at Canadian Forces Base Trenton in eastern Ontario Tuesday afternoon, just three days after he was killed during a training mission in the Afghan capital Kabul.

The 158th Canadian soldier to return from Afghanistan in a coffin, Greff was travelling between bases aboard an armoured NATO bus when a suicide bomber detonated a car packed with 700 kilograms of explosives.

Greff was killed in the massive blast alongside eight other soldiers, five civilian contractors and four Afghans including two children.

Greff is survived by his wife and two young children, all of whom were on hand for the repatriation at CFB Trenton Tuesday afternoon.

The family was joined by dignitaries including Governor General David Johnston, Defence Minister Peter MacKay and Chief of Defence Staff, Gen. Walt Natynczyk, to watch as Greff's flag-draped coffin was carried ceremoniously by military pallbearers from the C-17 Globemaster plane to a waiting hearse.

During the ceremony his widow Lindsay Raphael, pushing her newborn daughter in a stroller, placed two roses on the coffin. Her son was lifted up so he could place his own rose.

Other family members also paid their respects before the motorcade of hearse and limousines began the journey along the Highway of Heroes to the coroner's office in Toronto.

Greff, who was serving with the Edmonton-based Third Battalion of Princess Patricia's Canadian Light Infantry, was on his second tour of Afghanistan.

As one of the 900 Canadian soldiers who are taking part in the training there, Greff was working as a trainer and mentor to Afghan military personnel.

He is the first Canadian to die during the training mission slated to last until 2014.

In Ottawa, the New Democrat's defence critic David Christopherson called for an end to the training mission after question period on Tuesday.

"I think what Canadians now understand is that as long as we have soldiers in Afghanistan, they're going to be at risk," he said.

"Their lives are going to be at risk and most Canadians believe the effort we have made in Afghanistan is more than our fair share and that this is not the mission for us."
