What are some similarities between this preamble and the US preambles?

The preambles are similar in terms of their goals, structure, and some specific phrases. Both aim to establish a framework for a democratic constitutional nation and outline core ideals such as justice, liberty, peace, and happiness. They both begin with introductory phrases like "We, the People..." which indicate the people-centered approach to democratic governance. Moreover, the preambles share certain fundamental concepts about liberty, democracy, and pursuit of happiness. Overall, while the Preamble of Canada's Constitution Act emphasizes specific Canadian values and aspirations, it has common grounds with preambles such as that of the US declaration in terms of democratic principles and goals.
