About the records
These 8,437 files were created by the Circuit Court office in Montréal about people who applied for citizenship. Some files are for people who were born in Canada or Great Britain and became American citizens.
Before the Canadian Citizenship Act came into force on January 1, 1947, people born in Canada were British subjects. Immigrants born in Great Britain and the Commonwealth were already British subjects and did not need to apply for citizenship in Canada.
The archival reference is RG6 F3, volumes 876 to 958.
The files usually provide these details:
- name, age and place of birth
- former and present place of residence
- number of years residing in Canada
Most of the files include these documents:
- petition to be naturalized as a British subject
- oath of residence and oath of allegiance
- certificate confirming the oaths were taken
