StatsCan chief Munir Sheikh has resigned:
"I want to take this opportunity to comment on a technical statistical issue which has become the subject of media discussion. This relates to the question of whether a voluntary survey can become a substitute for a mandatory census.
It can not.
Under the circumstances, I have tendered my resignation to the Prime Minister."
