During OD or AD (not sure because we had both the same day) they will ask you some questions, i.e. Where are you from? What is your nationality? Do you hold a Canadian passport?
If you make it to the FI, you will fill some papers, including your nationality. Since you don't have the answer to your question, travelling all the way to Canada to attend OD is quite expensive to find the answer...
Best of luck : I really hope your dream of becoming CC will come true!
