Canadian Forces members with the 3rd Canadian division were streaming into Prince Albert on Monday and will be at the centre of the action in the La Ronge area within a day or two, provincial officials said.
Some 500 personnel will be patrolling the fire lines, putting out hot spots and providing logistical support doing such chores are moving fire hoses around. Many of them will be moving around in light armoured vehicles that can manoeuvre off the roads.
They're joining the more than 600 firefighters who've been battling the blazes for weeks.
More than 100 forest fires are burning in Saskatchewan today, and as many as 13,000 people have been forced to leave their homes. One of the worst-hit areas is around La Ronge, which is about 380 kilometres northeast of Saskatoon.
At least 7,000 evacuees are in shelters in Regina, Saskatoon, Prince Albert, Cold Lake, Alta., and other communities.
More army personnel could be deployed to fight the fires as conditions change, officials say.
