To date, there has not been a single case where citizenship was not granted. However, many expectant mothers who are new to this are rarely aware of it, and some even doubt: Is there really such a good thing? But the fact is exactly that! Canada implements a birthright citizenship system: as long as a child is born in Canada, they automatically possess the nationality of this country.
Internationally, there are generally three types of nationality policies: jus sanguinis, jus soli, and mixed principles. A total of 23 countries worldwide implement the principle of jus soli (those born within the airspace, territory, or territorial waters are citizens), but the only developed countries among them are the United States and Canada (other developed countries basically implement jus sanguinis). Furthermore, the current U.S. President has repeatedly stated that this birthright citizenship principle is unreasonable and that he wants to find a way to abolish it!
Canada's birthright citizenship system is stipulated by the Canadian Constitution, so no one can deprive a person born in Canada of their Canadian citizenship, not even if the child's parents make the decision for them! We can now definitively answer the question raised in the title: Is the nationality of a baby born in Canada really Canadian? Yes! Any child born within Canadian airspace, territorial waters, or territory is a Canadian citizen! Expectant mothers from our country who come to Canada to give birth can have their children automatically obtain Canadian citizenship, hold a Canadian passport, enjoy all the benefits enjoyed by all Canadian citizens, and be under the jurisdiction and protection of the Canadian government.
However, are there any exceptions? Yes! When the child reaches the age of 18, they can go through the process of renouncing citizenship in Canada and take an oath, which would mean renouncing Canadian citizenship and no longer being a Canadian citizen. However, no one has done this so far, because Canada allows dual citizenship, which does not conflict with your other nationalities, so in most cases, there is no need to do so.
Of course, if the child has better development opportunities in another country in the future, or takes on a high-level government civil service or military position that requires exclusive citizenship of that country (this refers to the child; in the vast majority of cases, it has nothing to do with the child's parents), then they would need to choose whether to retain their Canadian citizenship. In such a case, the child can come to Canada after reaching adulthood to go through the process of renouncing citizenship and then take an oath to relinquish their Canadian citizenship.
