Some of the people being evacuated from the remote Attawapiskat First Nation in northern Ontario have been taken to northern Quebec.
Emergency Management Ontario says about 350 people were flown to Val d'or.
Another 310 have been taken to the northern Ontario communities of Kirkland Lake, Fort Frances and Wawa.
EMO says 240 others will be taken to communities that have yet to be determined.
Attawapiskat First Nation leaders have declared an emergency due to the high risk of flooding and asked that about 1,000 vulnerable residents be moved out the community on the west coast of James Bay.
An evacuation involving more than 1,500 residents from the Kashechewan First Nation was completed last week.
