I wanted to click "no" but then got a pop up saying "even if you got a citizenship from the country you were born, you have to click yes"
So I selected "yes" and entered "Belgium, Citizen, -my date of birth-"
I have no idea if I did the right but I though to myself, better safe than sorry.
But it was very confusing.
I want to point out that, in French, the meaning is TOTALLY diffrent. In French (the language I filled it in) is: "Avez-vous déjà obtenu un statut d'immigrant ou la citoyenneté dans un pays autre que le canada ou que votre pays de naissance"
Which means in English: "Have you ever had immigration or citizenship status in any country other than Canada or your country of birth?"
So the FRENCH FORM IS WRONG and POORLY TRANSLATED
