The Hilary Weston Writers' Trust Prize for Nonfiction is a Canadian literary award, presented annually by the Writers' Trust of Canada to the best work of non-fiction by a Canadian writer.
Canada's most lucrative non-fiction prize, the winner receives a prize of CA$60,000 and all finalists receive CA$5,000.
[1][2] First established in 1997, the award's original corporate sponsor was Viacom.
Pearson Canada, an educational book publishing company, took over the award in 1999, and Nereus Financial, a stock brokerage, became the sponsor from 2006 to 2008.
After Nereus dropped its sponsorship, the award had no corporate sponsor until 2011,[3] when philanthropist and former Lieutenant Governor of Ontario Hilary Weston was announced as the award's new sponsor.
