Canada Census 2011: Not Scientifically Valid?

The December 2010 (Vol 7, no. 4) of Significance Magazine (a joint publication of the American Statistical Association and the Royal Statistical Society) has a piece by Jon Baskerville on the reduced 2011 census of Canada (as well as comments about reduced statistics in the UK) on page 172.

The piece ends with the observation, “…if Canada finds a compulsory census incompatible with the freedom of its citizens, will the world have to follow??”
