Dual Citizenship and Canada: What Happens to Your Original Citizenship
Canada allows you to hold multiple citizenships without restriction. The moment you take the Oath of Citizenship, you are Canadian — and Canada will never ask you to give up that status. The complication is that your country of origin may see things very differently.
What happens to your original citizenship depends entirely on the laws of the country that issued it, not Canadian law. For the five largest source countries of new Canadian citizens — India, Philippines, China, Pakistan, and Nigeria — the outcomes are different, and getting this wrong can have serious consequences for property rights, inheritance, travel, and family obligations back home.
India: Automatic Cancellation and the OCI Pathway
India is a single-citizenship country. Under Section 9 of the Indian Citizenship Act, you automatically cease to be an Indian citizen the moment you voluntarily acquire another country's citizenship. This happens on the date you take the Canadian Oath of Citizenship — not when you file paperwork, not when you apply for a new passport.
What you must do after becoming Canadian:
- Surrender your Indian passport to a BLS International center (India's authorized service provider for consular matters in Canada). You will receive a Surrender Certificate, which is proof that you have formally relinquished Indian citizenship.
- Apply for an Overseas Citizen of India (OCI) card. Despite the name, an OCI is not citizenship — it is a lifelong, multiple-entry visa that gives you near-resident rights in India.
What the OCI gives you:
- Visa-free travel to India, multiple entry, no expiry
- Parity with Non-Resident Indians (NRIs) in financial investments, education, and certain property purchases
- Eligibility to work in most sectors in India
What the OCI does not give you:
- The right to vote in Indian elections
- The right to hold constitutional offices or government positions
- The right to own agricultural land or farmland
- Consular protection as an Indian national
The OCI application is typically processed through BLS International and requires the Surrender Certificate plus proof of Canadian citizenship and relationship to India (your old Indian passport is usually sufficient). Processing takes approximately 12 to 16 weeks.
China: Strict Single-Citizenship, No Equivalent to OCI
China maintains one of the world's most rigid single-citizenship policies. Chinese law considers that a person automatically forfeits Chinese citizenship the moment they naturalize elsewhere. Unlike India, China has no OCI-equivalent program — there is no formal pathway to maintain any Chinese residency rights after naturalization.
Practical implications:
- You must enter and exit China using your Canadian passport with a Chinese visa
- Chinese authorities may not recognize you as a Canadian for consular protection purposes if they have records of your prior Chinese citizenship (though this is inconsistently applied in practice)
- Inheritance of property in China may face complications under Chinese law
- Some Chinese financial accounts and property registrations become legally ambiguous after naturalization
If you have significant assets or family obligations in China, consult a cross-border lawyer before taking the Canadian Oath. The decision is irreversible from the Chinese side.
Philippines: Dual Citizenship Permitted, But Not Automatic
The Philippines allows natural-born Filipino citizens to retain their Philippine citizenship after naturalizing in another country — but it is not automatic. Under Republic Act 9225 (the Citizenship Retention and Re-Acquisition Act), you must file an application with the Philippine consulate in Canada and take an additional Oath of Allegiance to the Philippines.
Once you have completed this process, you hold both citizenships fully. You can travel on either passport, vote in Philippine elections if registered overseas, and own property in the Philippines without restriction.
If you naturalize in Canada without completing the RA 9225 process, you technically lose your Philippine citizenship under default law. Many Filipino-Canadians delay the RA 9225 filing; it can be done after the fact, but processing can take several months and requires documentation of your natural-born Filipino citizenship.

Pakistan: Dual Citizenship Formally Allowed with Canada
Pakistan updated its arrangements for dual citizenship in 2024 and 2025, formally allowing Pakistani nationals to hold Canadian citizenship simultaneously. Pakistan now has bilateral dual citizenship agreements with 22 countries, and Canada is among them.
Pakistani-Canadians can hold both passports. You should still register your Canadian citizenship with the relevant Pakistani authorities if you intend to maintain property or family ties in Pakistan, but there is no requirement to renounce Pakistani citizenship when naturalizing in Canada.
This is a meaningful change for the large Pakistani-Canadian community — previously, the dual citizenship question was more legally ambiguous, and many applicants were uncertain about their obligations under Pakistani law.
Nigeria: Dual Citizenship Permitted for Natural-Born Citizens
Nigeria allows dual citizenship for natural-born Nigerians. You can become Canadian and retain Nigerian citizenship, with full rights to travel on a Nigerian passport, own property in Nigeria, and maintain Nigerian bank accounts. There is no formal surrender process required.
However, citizens who naturalized as Nigerians (i.e., obtained Nigerian citizenship through a formal process rather than by birth) do not have the same dual citizenship rights under Nigerian law. If you're in this category, consult the Nigerian High Commission for your specific situation.
Germany: Dual Citizenship Now Broadly Permitted
Germany changed its citizenship law in June 2024, allowing most German citizens to retain German citizenship when naturalizing elsewhere. Previously, this required a "retention permit" that was difficult to obtain. The reform now applies to most cases, though some exceptions exist. If you became Canadian before June 2024, you may have automatically lost German citizenship at the time — consult the German consulate about whether restoration is possible.
The General Rule: Research Before Taking the Oath
You are not required to inform your country of origin before or after naturalizing in Canada. Canada will not notify them. However, ignorance of your home country's laws doesn't protect you from their consequences.
If you have property, inheritance rights, voting registration, or professional licenses in your country of origin, the moment you take the Canadian Oath is when the legal clock starts in that country. The key questions to investigate in advance are:
- Does my country allow dual citizenship with Canada?
- If not, what happens to my property rights?
- Is there a formal process I need to complete (like the OCI application or RA 9225)?
- Will losing my original citizenship affect family members who remain there?
The Canada Citizenship Guide includes a dedicated section on post-oath obligations — including the OCI application process, the passport surrender timeline for Indian nationals, and how to manage the transition if you have ties to single-citizenship countries.
