The Berton has become a bit complicated. Presented for years by Canada's National History Society (first recipient: Pierre), it has now also acquired the governor general's patronage. So now it is announced as the "Governor General’s History Award for Popular Media: The Pierre Berton Award," which seems like an unfortunate bit of brand blurring. But there it is.
Congratulations to the Dictionary of Canadian Biography. I do still pull a copy off my bookshelf once in a while, but the go-to now is the online edition here.
