They are pushing out from Kandahar in southern Afghanistan into areas where the Taliban has returned after being defeated by U.S.-led coalition forces in 2001, the CBC's Kas Roussy said from the Kandahar base.
They intend to pacify the area, a necessary first step to improve local governance and people's lives.
Part of the forces' work involves opening a road from Kandahar City to the north.
"It is a dangerous mission," Roussy said. He added that the area the Canadians are moving into "is still very insecure."
U.S. officers who know the area said there are dozens of militants operating in several bands. Six U.S. soldiers and 18 Afghans, including civilians, were killed on duty in the area in 2005.
Few details are available for security reasons, but Roussy described seeing vehicles and soldiers preparing to leave the base over the previous 24 hours.
The mission could last until the end of the month.
There are 2,200 Canadians in southern Afghanistan, part of a multinational force led by Canadian Brig.-Gen. David Fraser.
A battle group from Princess Patricia's Light Infantry took over frontline duties in Kandahar from a U.S. task force in late February.
Since then, two Canadians have been killed in an accident, and five have been hurt. Five more were wounded in a suicide attack, and a sixth received a severe axe wound to the head from a Taliban militant, who was shot dead by other Canadians.
That was believed to be the first engagement between Canadians and the Taliban.
