I didn't know that Canada had a national registration by questionnaire in 1940.
The questionnaires included the following details:
- date of birth;
- marital status;
- number of dependents;
- place and country of birth of individual and his or her parents;
- year of entry into Canada (if an immigrant);
- racial origin;
- general health;
- occupation, employment status, farming or mechanical skills; and
- previous military service.
There was a different form for males and females regarding questions about occupation, work history and military service.
If the person has passed away more than 20 years ago or was born more than 110 years ago, it is possible to apply for information -- there is a $45 fee.
