The 2016 Governor General's Award in nonfiction goes to University of Saskatchewan historian Bill Waiser for
A World We Have Lost: Saskatchewan before 1905. From the jury statement:
"From its first page, Bill Waiser’s A World We Have Lost: Saskatchewan Before 1905 surprises the reader with its reconsideration of Canada. In a sweeping blend of narrative, historical detail, and compelling images, Waiser refocuses the country’s story by putting Indigenous peoples and environmental concerns in the foreground."
Since Waiser also wrote Saskatchewan: A New History, the history of the province since 1905, he has pretty much got Saskatchewan covered.
