I think once you become a citizen of Canada, you won't have to worry about that 10 year ban since Canadians have visa free entry and there isn't a database out there of people who have a 10 year bar. I think you just have to take a flight and show your passport to customs and they'll stamp it and let you in.

I feel bad for y'all. I got DACA before I turned 18 so I don't have to worry much about coming back to the US if I do qualify for express entry.
