Officers determined that two men inside the home, Conroy Keesaynew and Zachary Worm, were wanted on outstanding warrants for weapons-related offences in the Pierceland and Loon Lake areas.
A number of children were also reported to be in the house.
The area was contained and classes were cancelled at a nearby school due to the heavy police presence.
Approximately seven hours later, eight people were arrested at the home and six children, all under the age of 10, were located unharmed.
Three adults and two youth were arrested at a nearby home.
Eight people were released a short time later.
Keesaynew, 38, and Worm, 31, were scheduled to appear Thursday afternoon in Loon Lake provincial court on the outstanding charges.
Police said they continue to investigate.
Big Island Lake Cree Nation is approximately 320 kilometres northwest of Saskatoon near the Alberta boundary.
