Who is Sean Fine, and why has he been given this terrible assignment?

Many otherwise-reasonable Canadians are totally exasperated at Prime Minister Trudeau's often dubious choices (based on diversity and inclusiveness) for important government roles. To heck with (choosing my words carefully) the outdated idea of meritocracy ... both in the government and (now) apparently the press.
This seems as stupid (and ill-advised) as it is weirdly sadistic.
