Comprehensive Guide to Bill C-3: Navigating Canada’s New Citizenship by Descent Rules and Passport Eligibility
Understanding the 2025 Amendments to the Citizenship Act and the Removal of the First-Generation Limit
On December 15, 2025, Bill C-3 (An Act to Amend the Citizenship Act) officially came into effect, fundamentally reshaping how Canadian citizenship is inherited by individuals born or adopted outside Canada. This groundbreaking legislation permanently eliminates the restrictive “first-generation limit” (FGL) on citizenship by descent, restoring automatic rights to thousands of “Lost Canadians” and establishing a clear, multi-generational pathway forward based on a “substantial connection” to Canada.
For federal public servants, legal professionals, and families navigating the passport application or citizenship certificate process, understanding the precise statutory boundaries of Bill C-3 is critical.
The Evolution of Citizenship by Descent: Before vs. After Bill C-3
Prior to the enactment of Bill C-3, the Citizenship Act imposed a rigid cap on citizenship by descent. A Canadian citizen who was themselves born or adopted abroad could not pass citizenship down to their children if those children were also born outside of Canada. This systemic restriction was struck down as unconstitutional by the Ontario Superior Court of Justice on December 19, 2023, prompting the federal government to draft corrective legislation.
The table below breaks down how eligibility has altered following the implementation of Bill C-3:
| Legal Parameter | Before Bill C-3 (Pre-December 15, 2025) | Under Bill C-3 (On or After December 15, 2025) |
|---|---|---|
| First-Generation Limit (FGL) | Enforced strictly. Citizenship could not pass to the second generation born abroad. | Permanently Abolished. Citizenship can extend to second and subsequent generations. |
| Requirements for Pre-2025 Births | Disqualified automatically if born abroad to a parent who was also born abroad. | Automatically Restored. Citizenship is retroactively granted with no physical residency tests required. |
| Requirements for Post-2025 Births | N/A | Dependent on the Substantial Connection Test met by the Canadian parent. |
| Parental Physical Presence Test | Not applicable / No mechanism existed. | Requires 1,095 days (3 years) of cumulative physical presence in Canada prior to birth/adoption. |
| “Lost Canadians” Inclusion | Section 8 “Lost Canadians” and their descendants remained excluded from status. | Fully Included. Historical exclusions are corrected, and status is fully accessible. |
| Renunciation of Status | Subject to standard, complex regulatory review pathways. | Streamlined via a simplified renunciation process for those retroactively added. |

Strategic Framework: How to Secure a Canadian Passport via Bill C-3
A common administrative misconception is that newly eligible individuals can apply directly for a Canadian passport. Because Passport Canada requires definitive legal proof of citizenship before an identity document can be manufactured, applicants must follow a mandatory multi-step operational sequence.
- Collate Vital Statistics and Lineage Proof (Prerequisite Phase): Gather all legal, long-form birth certificates or official adoption records establishing an unbroken genealogical chain back to an original “anchor” ancestor (a person born or naturalized within Canada). Documents must clearly list parental names across every generation.
- Apply for a Canadian Citizenship Certificate (IRCC Processing Phase): Submit a formal “Proof of Citizenship” application to Immigration, Refugees and Citizenship Canada (IRCC). Note: If you had an active file caught in processing under previous interim enforcement measures, IRCC is automatically evaluating it under the new Bill C-3 statutes without requiring a fresh submission.
- Execute the Passport Application Workflow (Final Issuance Phase): Upon receiving your paper or electronic Citizenship Certificate, complete the standard Adult or Child Canadian Passport Application. Secure two identical passport photos, coordinate a qualified guarantor signature, and submit the package to a Service Canada branch or an overseas Canadian consulate/embassy.
Critical Operational Constraints and the “Substantial Connection” Doctrine
For children born or adopted abroad on or after December 15, 2025, passing down citizenship requires satisfying the Substantial Connection Test. To successfully transmit citizenship to a second-generation (or later) child born overseas, the Canadian parent must demonstrate at least 1,095 days (3 years) of cumulative physical presence within Canadian territory at any point in their life preceding the child’s birth or adoption.
Crucial Travel Warning for Commercial Border Crossings: Individuals who have automatically acquired Canadian citizenship via Bill C-3 but do not yet hold a physical Canadian passport face significant travel obstacles. Under Canadian border integrity laws, commercial airline carriers will deny boarding to citizens attempting to enter the country on an Electronic Travel Authorization (eTA) or a foreign passport. To avoid being stranded abroad, eligible individuals must complete the Citizenship Certificate and Passport sequence before booking international flights to Canada.
