Where citizenship stands
Two things dominate this area right now. A change in December 2025 made a large number of people citizens overnight, many of whom have no idea. And for everyone else, becoming a citizen is voluntary, which means the real question is what it changes rather than whether you qualify.
Since December 2025 many people are citizens already and do not know it
The first generation limit is gone. From 2009 until 15 December 2025, a person born or adopted outside Canada was not a citizen by descent unless their Canadian parent had been born in Canada or naturalised here. A citizen by descent could not pass citizenship to a child born abroad.
If you were born outside Canada before 15 December 2025 to a Canadian parent, in the second generation or beyond, then in most cases you are automatically a citizen, which is how the department itself puts it. Nothing needs to be granted to you. What you may need is a certificate proving it, which is a separate application and is not what makes you a citizen.
The Act carries narrow exceptions to that, so the words in most cases are doing work. The main two are a person who made a declaration of alienage before 1947, or before 1949 for Newfoundland, and a person who became a citizen by a grant and later renounced it. If either could describe you or an ancestor in your chain, the answer turns on the documents rather than on the general rule.
The reach back is generational. The chain of proof can run through several generations, provided there is a parent or parental ancestor who became, or would have become, a citizen on or after 1 January 1947, or 1 April 1949 for Newfoundland. Citizenship still passes from a parent, but the documents may go back much further.
- Nobody has to become a citizen. Permanent residence does not expire, and applying is voluntary with no deadline. The decision is about what changes rather than about a requirement.
- The residency obligation is the biggest practical difference. A permanent resident must meet 730 days in every rolling five years or risk losing status, and not all of those days have to be spent in Canada. Days outside Canada accompanying a citizen spouse or partner, or a parent in the case of a child, and days employed full time abroad by a Canadian business or in the federal or a provincial public service, count towards the 730. Humanitarian and compassionate relief is also available. A citizen has no residency obligation at all, and the intention to reside requirement that once applied to citizenship applicants was repealed in 2017.
- A citizen cannot be removed. A permanent resident can be, for serious criminality or for breaching the residency obligation. The only exposure a citizen has is revocation for fraud, and that is a different thing decided in a different forum.
- Citizenship by descent is automatic, not granted. If it applies to you, you are already a citizen and always were. The application you make is for proof.
- The presence rule is not simply five years of living here. It is 1,095 days in the five years before you apply, of which the department says 730 must be as a permanent resident, with earlier time counted at half and capped.
- Your permanent resident card is taken at the ceremony. The permanent resident card is collected or destroyed when you take the oath, so a Canadian passport becomes essential rather than optional for travel.
What changes when you become a citizen
| Permanent resident | Citizen | |
|---|---|---|
| Residency obligation | 730 days in every rolling five years. Days abroad accompanying a citizen spouse, partner or parent, and days employed full time abroad by a Canadian business or in the federal or a provincial public service, count towards them, and humanitarian and compassionate relief exists. Breach can cost you the status | None |
| Right to enter Canada | No absolute right. You need a valid permanent resident card to board a commercial carrier, or a travel document if you are abroad without one, and you are screened on arrival | A constitutional right to enter, remain in and leave Canada. As a rule you fly here on a Canadian passport and cannot use an electronic travel authorisation. A Canadian American dual citizen is the exception and may travel on a valid United States passport instead |
| Voting and running for office | No | Yes, at every level |
| Removal from Canada | Possible, for serious criminality or for breaching the residency obligation | Not possible as a citizen. The only exposure is revocation for fraud. Where the fraud was in the citizenship process only the person reverts to permanent resident status and keeps the right to remain, and becomes a foreign national only where permanent residence itself was obtained by false representation |
| Some security cleared employment | Closed to some roles | Open |
| Health care, social benefits, work and study anywhere in Canada | Yes | Yes |
Dual citizenship is permitted in Canada. A dual citizen other than a Canadian American ordinarily flies to Canada on a Canadian passport. The special authorisation for a short trip is narrower than it sounds. You must not be a Canadian American dual citizen, the flight must be within 10 days, the other passport must be from a visa exempt country, you must already have held a citizenship certificate or a Canadian passport or have been granted citizenship after permanent residence, and the authorisation lasts only 4 days.
