Are you referring to the1911 Census of Canada, that was taken in Ontario? If so, I have 6 records, and they were taken on the following dates:
June 1, 2, 5, 6, 8, 29, and one record that is undated.
Thank you Chuck! Yes, the 1911 Canadian Census taken in Ontario. My record was undated. Now I know, :)
From the National Archives
Under instructions from the Minister of Agriculture, 264 commissioners and 9 703 enumerators were to begin work on Thursday, June 1 and continue working every day, except Sunday, until the work was completed. Enumerators in the Northwest Territories and the Yukon were authorized to begin before June 1, so they could complete their work by the end of that month. By February 26, 1912, all the reports were received; over 96 percent of them had entered the statistics office by the end of August.
That was interesting, Victor, thanks. I noticed on the 2010 US Federal census that it started in Alaska weeks before the lower 48 states.
