Officials say members of the Baagwatting Community Association pledged $100,000 to help Attawapiskat residents and the aid will be delivered Thursday.
The aid includes 250 water purification systems, water purification tablets, 300 adult and child hygiene kits, medical supplies and 300 sets of thermal clothing.
The team delivering the aid will include a Durham Region police officer, two paramedics, one each from Durham Region and Toronto EMS, and a water technician.
They are members of the Ontario Volunteer Emergency Response Team, which operates out of Durham Region.
The Attawapiskat First Nation declared an emergency in October because 25 families were living in housing too flimsy to face the harsh winter.
Ottawa has placed the band's finances in the hands of a third-party manager, a decision that has infuriated band leaders and sparked a legal fight.
