Canadian
If you were born in Canada, you are automatically Canadian for life. Even if you have become Canadian, you retain that nationality, even if you no longer live in Canada. Incidentally, you can also have become Canadian if you have a parent who is Canadian. This is true even, with some restrictions, if you were born outside of Canada.
European
The rules regarding citizenship in European countries are sometimes complicated and they are not the same in all countries of the Union.
The rule of thumb is that you have European citizenship if at least one of your parents also had it.
However, you can lose it, for example if you voluntarily acquire Canadian citizenship.
Dual nationality
There are countries where it is sometimes looked at strangely if you have more than one nationality. Yet it can happen. A good example is someone who has parents of different nationalities.
In Canada, keeping another nationality is not a problem at all. The country has been used to it for a long time.
In some European countries, the concept of dual nationality is also becoming more normal.
However, it is definitely worth a thorough investigation to see whether you may also have dual nationality.
The rule of thumb is that if you can get a passport from a country, you are a citizen. But you can also be a citizen of a country if you have never had a passport from it. Or if it has long since expired.
Advantages
There are interesting advantages to holding more than one nationality. For example, you are always welcome in that country. After all, you can always come home.
As a citizen you are entitled to certain consular services. Sometimes this can be important.
As a citizen, you can also pass on this privilege to the next generation.
Furthermore, there are conceivable cases where you could get an easier border crossing somewhere with a certain passport.
Do you know now?
It is absolutely essential that you realize which nationality(ies) you possess. If in doubt, it is a good idea to ask quickly.
If you ask the Consulate in writing, you will have some evidence in your hands. But it often takes a long time before you hear anything back.
