Emergency Management Ontario says flights began Friday night to evacuate some 100 members of Moosonee to Sudbury, while a similar number are set to be taken Saturday to Timiskaming Shores.
EMO has said Moosonee's mayor requested the precautionary evacuation of about 246 people — including escorts — from the community of about 3,500 residents, which isn't connected to the road system.
It says Kashechewan First Nation, which sits further up the James Bay coast, has declared an emergency in anticipation of Albany River water levels rising due to ice breakup in the coming days.
EMO says Kashechewan had 240 of its residents evacuated earlier this week due to a rapid snow melt that overwhelmed the community's sewer system and left 40 residences without heat or power.
It says a total of eight communities in the province's north are under state of emergency warnings, most due to rising water levels.
Meanwhile, farther south emergency declarations remain in place for Bancroft, Kawartha Lakes, Minden Hills, and Sagamok First Nation as authorities deal with flooding.
