The Conservative government is scrapping the mandatory long census form for the 2011 census, replacing it with a voluntary national household survey. All Canadians will still receive a mandatory short census. One in three households will be sent the new household survey as well. Previously, one in five households were sent the mandatory long-form census.
While more people will receive the longer survey, the fact that it is voluntary means Statistics Canada will have to double its efforts to get people to respond.
