The indexed data for the 1911 census of Canada became available world-wide on www.ancestry.com in January 2006.
This was the fifth census that Canada had held, and asked far more questions of the population than ever before,
there are over forty columns of data on the census form as well as details of the Provence, District and Town or Parish.
When searching the database be aware that your Joslin may be spelt in many ways, be very sceptical and adventurous
and think that some of the enumerators & families would have been French speaking, especially in the Quebec areas  
The 1911 census was begun on 1 June 1911 and includes nine provinces;
Alberta, British Columbia, Manitoba, New Brunswick, Nova Scotia, Ontario, Prince Edward Island,
