Yes, I'm now a Canadian citizen. Oh of course I'm still an Irish citizen and always will be, but I have sworn allegiance to the Queen of Canada. (I've also noticed that she quite resembles the Queen of the United Kingdom of Great Britain and Northern Ireland. Odd.) And having studied for (and apparently passed) the citizenship test I'm more Canadian than many Canadians themselves - well at least when it comes to answering questions such as "Who is the Lieutenant-Governor of Quebec?" Go on, who is it then? No, you can't Google it; for the test you get pencil and paper, that's it.
The citizenship ceremony was really interesting. We were told that there were 400 of us, from 68 different countries. Almost everyone I met spoke French; the popular perception is that most immigrants in Montreal choose to learn English rather than French but that isn't what I observed. The ceremony itself was in both languages, and we sang the bilingual "Oh Canada" that everyone in Montreal knows from watching the Habs games.
The presiding judge for the ceremony was Renée Giroux. She gave a speech, mostly in French, with two main themes: volunteering in your community as a way of being a good citizen, and that women in Canada have the same status and opportunities as men. She illustrated the latter by pointing to herself, a female judge, and asked the new female citizens to aim high.
I'm proud to be Canadian. Of course the Canada I know is actually Quebec, but for the foreseeable future the Canadian flag will continue to fly here so that's my flag now.
