The Mounties say the 24-year-old woman was attacked while on her way home early Saturday morning in Little Grand Rapids.
Her body was found at a construction site hours later in the community 300 kilometres northeast of Winnipeg.
A forensic investigation determined she died from the animal attack and her death is not suspicious.
"She will always be remembered as a loving, caring mother and a person of great character."
RCMP are not naming the woman but several media reports identify her as Donnelly Rose Eaglestick.
"She will always be remembered as a loving, caring mother and a person of great character," the Southern Chiefs' Organization wrote on Facebook.
Dozens of people from the First Nation gathered Sunday night at a candlelight vigil to remember the young mother.
