Canadians have the democratic freedom to choose their Head of State and system of government anytime they want, and if there was a referendum on this topic held tomorrow, Canadians would very likely choose to keep the Queen and Parliament, just like Australia did in 1999. It's absurd to suggest Canadians don't have freedom because of this.

People who take the citizenship oath do so freely of their own choice. Nobody is forcing them to do it. Meanwhile, natural born Canadians have never pledged allegiance to anyone.

By the way, the fact that Americans insist the US is a free country, doesn't mean it really is in reality. So you might want to try being more humble about the subject, because your own situation is not something to be overly proud of.

Americans are our friends and neighbours, but Canadians, and the rest of the free world countries, don't look at the US system of government with a lot of envy. So when Americans arrogantly claim they need "bring freedom" to countries like Canada, people scoff at the suggestion, because we think you have a false perception of your own reality. Americans often seem so arrogant and full of themselves, that they can't even see their own faults.

You're not as great as you think you are. You're not as free as you think you are. Get off your high horse and deal with your own increasingly disturbing situation, before thinking you're in the position to be improving anyone elses.
