As you grew up in Canada you are already a citizen. What is the name used in your citizenship ID and Canadian passport. You have to use that name.
I'm not a citizen, I was born in Japan but moved to Canada at a young age and grew up there. I'm still a PR. My PR card and Japanese passport is in my Japanese name. But I'm just wondering if my english name will affect me in any way. It is not registered. Most of my ID in Canada is in my english name but, as I said, my primary IDs are in Japanese.
