Lets wait for OP's response, because a real pacifist would rather be shot than shoot. In which case, OP should answer NO to the question without regard to what happens with their citizenship.
Otherwise they're betraying themselves for what? Visa free travel to most countries? In that regard, Canadian Citizenship is better, so they should head north.
Life is not that easy in real world. It is not that any country's citizenship can be just aquired when you need it. It is also impossible for anyone to just go back
in time by 10 years and restart a different path of life.
