Canada dual citizenship: clearly allowed
Canada receives the top rating of 100 out of 100 points for allowing dual citizenship. The assessment is straightforward: Canada generally does not require naturalized citizens to give up their previous citizenship.
For long-term movers, that is a major advantage. A person who becomes Canadian can often keep family, property, inheritance, work or return ties to another country. The important caveat is that Canada controls Canadian law only; the other country may treat multiple citizenship differently.
What the measured value means
The measured value is not a complex index here. It reflects the legal position that multiple citizenship is generally accepted by Canada. That makes the rating especially stable because it depends less on processing culture and more on the basic citizenship framework.
The top rating follows from the fact that Canadian naturalization does not normally force a choice between Canada and a previous passport. For internationally connected families and professionals, that can reduce one of the biggest psychological and legal barriers to citizenship.
What Canada allows and what it cannot control
Canada recognizes that Canadian citizens can also be citizens of another country. It does not decide whether the other country keeps, restricts or removes that citizenship. Some states prohibit dual citizenship, require prior permission or treat foreign naturalization as a loss event.
Applicants should therefore check both sides: Canadian rules and the rules of their other citizenship. This is especially important for countries with military service, tax residence implications, property rules, reporting duties or restrictions on political rights.
This matters for families as well as individuals. Children can acquire nationality by birth, descent or later naturalization, and the legal effect may differ across countries. A household can therefore have several citizenship situations at the same time.
The practical conclusion is that Canada's openness removes a major Canadian-side barrier, but it does not remove the need to understand the other passport. That is why the indicator is very strong while still needing careful personal planning.
Travelling with two passports
Travel planning is also important. Canada tells dual Canadian citizens to travel to Canada with a valid Canadian passport or travel document in many circumstances. The passport used for boarding and entry can therefore matter even when dual citizenship itself is allowed.
When travelling to the other country of citizenship, that country may treat the person as its own citizen. Canadian consular protection can be limited in those situations. This does not weaken Canada's openness, but it is a practical point that dual citizens should understand.
Dual citizens should also keep documents consistent. Names, birth dates and passport details should match across travel bookings and official records where possible, because mismatches can create avoidable boarding or border questions.
Naturalization is still a separate process
Allowed dual citizenship does not mean automatic citizenship. Applicants must still meet the normal citizenship requirements, including permanent resident status, physical presence, language and knowledge requirements where applicable, and correct documentation.
The strength of this indicator is therefore not that citizenship is instant. It is that, after qualifying, Canada does not add a general requirement to renounce a previous nationality.
What this indicator does not measure
This indicator does not measure how quickly citizenship is granted, how strong the Canadian passport is or whether the other country allows dual citizenship. Those questions belong to separate indicators.
It also does not measure tax residence. Citizenship, residence, taxation and reporting duties can interact, but they are legally different issues.
Frequently Asked Questions
Does Canada require renunciation of a previous citizenship?

In many cases, yes. Canadian citizens should check Canada's official travel-document guidance before boarding a flight to Canada.
Does dual citizenship remove the normal naturalization requirements?
No. Multiple citizenship is allowed, but the applicant must still qualify for Canadian citizenship through the normal process.
