Bill C3 Citizenship By Descent FAQ Hub
This resource provides a high-level overview of common questions and legal considerations surrounding Canadian citizenship, specifically in light of Bill C-3 (An Act to Amend the Citizenship Act, 2025). This information is intended for general educational purposes and does not constitute legal advice or a formal service agreement.
1. 💍 Spousal Sponsorship
Can I sponsor my spouse or partner to move to Canada?
Once citizenship is confirmed, one acquires the legal right to sponsor a spouse or common-law partner for Canadian Permanent Residence under the family class rules. This process typically takes between 11 and 14 months. Please be advised that spousal sponsorship is a distinct legal proceeding governed by a separate set of IRCC regulations; as such, it would not be included in your citizenship by descent mandate and would require a new service agreement.
2. 👨👩👧👦 Adoption
How does Bill C-3 affect international adoptions?
For adoptions completed BEFORE December 15, 2025: If you were adopted abroad by a Canadian parent (even a parent born abroad) before this date, you are likely now eligible for a direct grant of citizenship. Under Bill C-3, the “First Generation Limit” that previously blocked second-generation adoptees has been removed retroactively. There is no residency requirement for the parents in these retrospective cases.
3. 📑Tax Obligations (The "US vs. Canada" Difference)
Does becoming a Canadian citizen mean I have to pay Canadian income tax?
No. Canada taxes based on residency, not citizenship. Becoming a Canadian citizen does not automatically make you a Canadian tax resident. If you live and work outside Canada and do not maintain significant residential ties, you are generally not taxed in Canada on your foreign income.
However, if you move to Canada and become a tax resident, you must report and pay tax on your worldwide income. Non-residents may still be taxed on certain Canadian-source income.
This differs from the United States, which taxes based on citizenship. U.S. citizens must file U.S. tax returns on their worldwide income regardless of where they live. As a result, individuals who hold both U.S. and Canadian citizenship and reside in Canada may have filing obligations in both countries.
Canada and the United States have a tax treaty designed to reduce double taxation. Taxes paid in one country can generally be credited against taxes owed in the other.
Important Notice: Because tax laws vary significantly based on your specific global assets, income sources, and duration of stay, you must contact a qualified tax professional or cross-border accountant for a formal determination of your tax obligations.
4. 🏠 Property Purchases & "Non-Resident" Taxes
Are there special rules for citizens buying property in Canada?
As Canadian citizens, you are not affected by the Foreign Buyer Ban on purchasing residential property.
However, if you own property in Canada while living abroad, other housing-related taxes may still apply depending on the province or municipality and how the property is used. For example, some areas charge taxes on homes that are vacant, underused, or not used as a primary residence. These rules are typically based on residency and occupancy, not citizenship.
If you plan to purchase property while living outside Canada, it is simply important to check the local rules where the property is located.
5. 🩺 Healthcare (The "Waiting Period")
Do I get immediate access to free healthcare?
No. Citizenship does not equal immediate free healthcare. To access provincial healthcare (OHIP, RAMQ, etc.), you must physically move to a province and establish residency. Most provinces have a 3-month waiting period before coverage begins. We advise maintaining private travel insurance for your first 90 days if you relocate.
6. 🗳️Voting Rights
Can I vote if I live outside of Canada?
Yes. Canadian citizens living abroad can vote in Federal elections via mail-in ballot, regardless of how long they have been outside the country (thanks to a 2019 Supreme Court ruling).
7. Dual Nationality: Canada and the United States
Dual citizenship means that a person is legally recognized as a citizen of more than one country at the same time.
Is dual citizenship allowed in Canada and the United States?
Yes. Both Canada and the United States permit dual citizenship.
Canada permits dual or multiple citizenship and does not require individuals to renounce another nationality when becoming Canadian. In most cases, no separate application or declaration is required to hold dual citizenship — it arises automatically if another country also recognizes you as its citizen under its own laws.
How does dual citizenship affect travel?
Entering Canada
✈️ By Air
- Canadian citizens must use a valid Canadian passport to board a flight to Canada. This applies even if you hold another citizenship.
- The only narrow exception is Canada-U.S. dual citizens, who may sometimes board with a U.S. passport plus proof of Canadian citizenship, but airlines may still deny boarding — so a Canadian passport is strongly recommended.
🚗 By Land or Sea (car, ferry, cruise, train)
- The “Canadian passport required” rule does NOT strictly apply. Canadian citizens can enter Canada with:
- Canadian passport (recommended), OR
- Other proof of Canadian citizenship + valid ID (e.g., citizenship certificate, birth certificate)
Canada cannot refuse entry to its own citizens, so border officers can admit you once citizenship is established.
Entering the United States
Under U.S. law, U.S. citizens — including dual citizens — must use a valid U.S. passport to enter and leave the United States.
8. 🐶 Bringing Pets to Canada
What are the requirements for moving to Canada with pets?
All dogs and cats over 3 months of age must have a valid rabies vaccination certificate (in English or French). If it is the animal’s first rabies vaccination, it must be administered at least 30 days before entry into Canada. Upon arrival, pets may be subject to inspection by the Canada Border Services Agency or the Canadian Food Inspection Agency. An inspection fee (approximately $30 CAD plus tax for the first animal) may apply. Please note that breed-specific rules may also apply at the provincial or municipal level. For example, Ontario has restrictions on pit bull–type dogs under provincial legislation.
9. 🛂Travel Documents & Verification
Can I travel to Canada immediately as a Canadian Citizen?
No. Before travelling as a Canadian citizen, you must first obtain proof of your citizenship — typically a Canadian Citizenship Certificate and/or a Canadian passport. A Citizenship Certificate is required in order to apply for a Canadian passport.
Additional guidance on travel requirements for dual citizens is provided in the Dual Citizenship section above.
10. 🎓Education & Higher Education
Do I qualify for domestic tuition rates at Canadian universities?
Generally, yes. Canadian citizens are eligible for domestic tuition rates, which are significantly lower than international student fees.
However, to qualify for the lowest “in-province” tuition rates or provincial student aid programs (such as OSAP in Ontario), you must typically establish residency in that province. This usually requires living there for at least 12 consecutive months before beginning your studies (excluding time as a full-time student).
11. 🇨🇦 Provincial Differences & Bill C-3
Does Bill C-3 apply differently depending on which province I move to?
No. The Citizenship Act and Bill C-3 are federal laws, meaning the rules for becoming a citizen or passing citizenship to your children are identical across all provinces and territories. However, once you arrive in Canada, “residency-based” benefits (like healthcare, tuition subsidies, and certain property taxes) are managed by the individual provinces. While your status as a citizen is federal, your benefits will depend on the specific rules of the province where you settle.
