Naturalization After 1917
Naturalization records created after 1917 are more detailed than earlier naturalizations, indicating the surname, given name, date and place of birth, entry into Canada, and in some cases, the names of spouses and children.
A typical record may consist of an Application for a Decision, a Royal Canadian Mounted Police Report, a Petition for Naturalization, an Affidavit Proving Petition, an Oath of Allegiance, and other documents and correspondence
