Officials declared an emergency in the James Bay Coast community on Friday after a fire broke out earlier this week in a set of trailers being used as temporary housing due to a sewage system break.
No one was injured in the fire.
Two flights were scheduled Saturday to fly the evacuees to Kapuskasing, said Charlie Angus, the NDP Member of Parliament for the area.
The Ontario government is arranging the air transportation.
The Provincial Emergency Operations Centre of the Office of the Fire Marshal and Emergency Management is working with Aboriginal Affairs, Northern Development Canada and municipal leaders.
Angus says the housing complex is a "giant set of construction trailers with little holding cells that families are living in."
In 2011, Attawapiskat became a flashpoint for relations between the federal government and First Nations after a housing crisis triggered a state of emergency.
