Some people had already left Stanley Mission due to thick smoke from the fire, which has blanketed the community for several days.
On Saturday, the Lac La Ronge band decided that around 1,300 residents who remained also needed to leave.
A wind shift was the reason for the decision.
Evacuees are now staying in La Ronge, Prince Albert and Saskatoon.
The fire is about 10 kilometres from Stanley Mission and isn't near homes, but power lines into the community are threatened.
In addition to using their own cars, residents were being bused out of the community until 2 a.m. Sunday morning.
"The people I've seen and spoken to at the reception centres all seem quite settled. They understand that there's a risk but this isn't that unusual for people living in the north and everyone was calm and settled at the reception centre," said Deanna Wysoskey, and emergency services co-ordinator with the province.
Additional aircraft have been flown in from Ontario to help Saskatchewan's own planes fight the blaze.
A small group of residents will stay in the community to provide home security and care for any pets that had to be left behind.
