The bodies of three more Canadian soldiers slain in Afghanistan have been returned to Canadian soil.

A military aircraft carrying Cpl. Thomas Hamilton, Pte. John Curwin and Pte. Justin Jones touched down at CFB Trenton at about noon on Tuesday. All three served with Golf Company, 2nd Battalion, RCR based in Gagetown, New Brunswick.

A motorcade transported their caskets along the Highway of Heroes into Toronto for a standard post-mortem event.

They arrived on the eastern outreaches of Scarborough around 3 p.m. ET. People greeted the motorcade with Canadian flags and yellow ribbons. Some stood silently, and other applauded as the motorcade passed.

The OPP put out a news release Tuesday morning urging people not to pull over to the side of the 401 when they see the motorcade pass.

"Cars parked on the shoulder and people standing on the side of the road are a hazard to traffic on the road and to those who have stopped," it said.

Instead, they want motorists to pull right off the highway.

Having Canadians gather on the overpasses to show respect for returning fallen soldiers is a growing tradition -- one last exercised about a week ago when three other soldiers died.

Cpl. Mark Robert McLaren, Warrant Officer Robert John Wilson and Pte. Demetrios Diplaros, were from the 1st Battalion, Royal Canadian Regiment, based out of Petawawa, Ont. They died on Dec. 5. Their deaths brought Canada's military death toll in Afghanistan to 100 since 2002. The toll is now 103.

In both incidents, the soldiers died as a result of roadside bombs.

On Tuesday morning in Afghanistan, Lt.-Gen. Michel Gauthier told reporters that two insurgents had been killed while trying to plant roadside bombs on the same stretch of highway that claimed the six Canadian lives.
