Citizenship and Immigration Canada holds records of naturalization and citizenship from 1854. The originals of records dated between 1854 and 1917 have been destroyed. However, a nominal card index has survived, which provides information compiled at the time of naturalization, such as present and former place of residence, former nationality, occupation, date of certification, name and location of the responsible court. The index rarely contains any other genealogical information.
Records created after 1917 are more detailed, indicating the surname, given name, date and place of birth, entry into Canada, and in some cases, the names of spouses and children. The file will typically include the original petition for naturalization, a Royal Canadian Mounted Police report on the person, the oath of allegiance, and any other documents.
Many people were naturalized under acts prior to 1914, and therefore, the original naturalization records no longer exist. However, if they interacted with the department in later years, those papers may still be available. Examples are Series E certificates, which were often issued to persons whose fathers or husbands had been naturalized earlier. The person was technically already naturalized through the naturalization of the father or husband. If the person later wanted a naturalization certificate, he/she could apply for one. Those application papers normally include much of the information that was on the father's/husband's pre-1914 papers, now destroyed.
Under the 1914 Act, naturalization certificates were issued based on the category of naturalization. Each certificate bore a letter (A, B, D, C or E) referred to as "the Series," and a number. Certificates issued in French also include the letter F after the number.
