The landscape of Canadian citizenship is now undergoing one of its most important transformations in history. In December 2025, the Government of Canada passed Bill C-3, an amendment to the Citizenship Act that has completely changed how citizenship is granted, especially for people from overseas or adopting abroad.
These changes are there to modernise citizenship law, make it more inclusive, and cut off completely outdated ways that families live nowadays under the new citizenship rules Canada 2025. The most significant change is the abolition of the old first-generation threshold for citizenship by descent, which prevented second and subsequent generations born overseas from automatically becoming Canadian citizens.
Under the new rules, many individuals previously excluded from citizenship can now apply for proof of status, while future cases depend on a “substantial connection” to Canada demonstrated by at least three years of physical presence by a Canadian parent. This update brings clarity, fairness, and broader eligibility, benefiting countless immigrants and families worldwide.
What the New Citizenship Rules Change in 2025
In December 2025, Bill C‑3 of the government of Canada officially changed the Citizenship Act by amending the rules about how people are granted citizenship through descent. Decades ago, only the first generation of Canadian citizens born in a place other than Canada was able to automatically obtain citizenship through a parent who was also Canadian; that is, if one’s grandparents were born in Canada, then it could be used to make going forth to invest only possible.
But if both one’s mother and oneself had each been born outside of their homeland, for instance, then even though they could boast an imported pedigree of their forefathers, this would not guarantee that they would ever be able to return home. Hence, the new provisions provide greater flexibility in such matters for those born overseas with some level of ancestral connection to Canada. Now, people who the old laws would have considered to be Canadian citizens but who are not so qualified can register. Kids born on or after December 15, 2025, must satisfy a ‘substantial connection’ test to prove Canadian citizenship passed from their parents.
Ending the First‑Generation Limit
One of the most dramatic changes in the rules is the removal of the old one-generation limit for gaining citizenship through descent. Previously, Canadian citizens born outside the country could not give automatic citizenship to their children, unless those children were also born abroad to one family. This restriction, in many cases, is erased by C‑,3, allowing common citizens (in effect) to flow into the next generations as long as several original conditions are satisfied. Importantly, those born before the law was changed and by this rule have lived in its shadow may now be recognised as citizens. Their right to Canadian citizenship depends only on whether they file for proof of citizenship. This represents a big change to a legal system that many considered outmoded and unfair for families living overseas.
The Substantial Connection Requirement
Under the new framework, whether a child born or adopted abroad on or after December 15th, 2025, can inherit citizenship depends on whether the Canadian parent has a close enough connection to Canada. To meet this requirement, the parent would have to have been physically present in Canada for at least 1,095 days (about three years) before the child’s birth. This sets such children off from those who inherit citizenship merely by descent: they must also have a real connection to Canadian society. Time spent in Canada as a resident, employee or student can count as time spent towards meeting this requirement. In substance, the present regulation offsets general qualifications against specific ties to Canada.
“Lost Canadians” and Citizenship Restoration
The phrase “Lost Canadians” defines those who were formerly not defined as Canadian citizens by outdated legal provisions such as the first‑generation rule and earlier historical restrictions. Under the new laws- find subsistence for these people, as well as for their generations The children of such people may apply for proof that they are Canadian citizens Once they have this proof, they can get a Canadian passport and enjoy the full rights of other Canadians. By bringing back the rights of these citizens this changes also right the historic wrong done to thousands of people throughout the world.
How to Apply Under the New Law
Applying for proof of citizenship with Immigration, Refugees and Citizenship Canada (IRCC) is the first step for most immigration applicants under our current laws. Even if you become a citizen automatically after October 1, 1977, it’s essential for travelling and other legal purposes to have a certificate of citizenship. When you apply for certificates of citizenship for children affected by substantial connection, IRCC staff will require several documents as proof that your Canadian parent met the physical presence requirement in Canada through prescribed periods. IRCC reviews applications and issues certificates as proof of Canadian citizenship under the law; this is required for passport applications and border entry.
Other Requirements and Practical Tips
The principal thrust of the 2025 Amendments will be naturalisation by descent, but normal citizenship requirements still hold for those other applicants seeking Canadian citizenship in this way, including residency, linguistic ability and understanding of Canada. Furthermore, processing fees and procedural occasions may well have altered since that time. Always check for the most current fee schedule and documentation requests at official IRCC websites before you apply. Knowing in advance and meeting the new requirements will reduce stalling time and ensure that applications are all in order, complete and correct.
