Before this morning, if I were asked to name the best contemporary Canadian author in English*, I would have responded, without hesitation, Robertson Davies (yes, I know he died in 1995, but for me, he is still a vital author). If pressed for another example, I would have mentioned Margaret Atwood. If pressed for a third example, I would have named Michael Ondaatje. If asked for a fourth example, I would have called out Mordecai Richler (died 2001). I might at some point have referred to Leonard Cohen, whom I consider to be a Canadian poet.
We would have gone fairly far down the list before I would have named Alice Munro.
(*I regret that I am woefully ignorant of contemporary Canadian authors in French or other languages.)
