National Registration File 1940-1946 (a Census Substitute)

A good census substitute is The National Registration File of 1940 in Canada

This was the registration of all people 16 years of age or olde, from 1940 to 1946. There is a great deal of information on this Registration. This is another way to
find an ancestor in that time period.

Statistics Canada holds these records and for a fee they will search on your behalf. See the explanation and an online order form
