Glossary of IRCC and Canadian Citizenship Terms

This glossary defines the 30 terms that recur across every Canadian citizenship application: the federal agencies involved, the immigration statuses that determine how days count, the calculation vocabulary IRCC uses, the language tests, the documents you will need to file, and the adverse situations that can stop a grant. Each definition links to the long-form guide where the term is used in context, and to the relevant page on Canada.ca or the Citizenship Act.

Government acronyms

IRCC — Immigration, Refugees and Citizenship Canada: The federal department that processes permanent residence, citizenship grants, refugee claims, and visa applications. IRCC sets the rules interpreted throughout our citizenship requirements guide. See the IRCC home page.
CBSA — Canada Border Services Agency: The federal agency that controls Canada's borders, records every traveller entry, and produces the Travel History Report used to verify physical presence. See the CBSA home page and our physical presence guide.
CRA — Canada Revenue Agency: The federal agency that administers tax law. IRCC checks CRA records to confirm that an applicant met the income-tax filing obligation for 3 of the 5 years inside the eligibility window. See the CRA home page.

Immigration statuses

Permanent Resident (PR): A non-citizen with the right to live and work in Canada indefinitely. PR is the status during which days count one-for-one toward the 1,095-day rule. Read the eligibility guide.
Temporary Resident: A person in Canada on a study permit, work permit, or visitor visa. Time as a temporary resident before becoming a PR counts as half-days, capped at 365 half-days. See the calculation guide for the cap.
Protected Person: A person Canada has formally protected from removal because of risk in their home country, including positive refugee claimants. Pre-PR days as a protected person count as half-days toward citizenship.
Convention Refugee: A person Canada has recognized as meeting the United Nations Convention definition of a refugee. Convention refugees are a sub-category of protected persons and follow the same pre-PR half-day rules.
Crown Servant: A federal public servant or member of the Canadian Armed Forces. Days abroad in Crown service count as Canadian days under section 5(1.03) of the Citizenship Act, and the credit extends to accompanying spouses and dependants. See our special cases section.

Calculation concepts

Physical Presence: The total number of days an applicant was physically inside Canada during the 5-year eligibility window — every calendar day where the applicant set foot in Canada counts as a full day. See the full physical presence guide.
Eligibility Period: The 5-year window immediately before the signature date during which IRCC counts days. Days outside the window — even as a PR — do not count. Read the step-by-step calculation guide.
Half-day: A pre-PR day in Canada that counts as 0.5 days toward the 1,095-day rule. Half-days apply to time as a student, worker, visitor, or protected person and are capped at 365 half-days (182.5 days of credit). See the FAQ on half-days.
1,095-day rule: The statutory threshold of 1,095 days of physical presence within a 5-year window required by section 5(1)(c) of the Citizenship Act for a citizenship grant.
Backwards calculation: The method of computing the 5-year eligibility window by starting at the planned signature date and counting backward exactly 5 years. Worked through in the calculation guide.
