As for the principle of the separation of church and state you are dead wrong as to interpretation. This website is filled with quotes from Thomas Jefferson, author of the American version of the principle. He couldn’t have been more clear as to what it meant. A search on Google will quickly reveal this.

You are correct in saying that Canada has never formally adopted the principle. Few states have. It is, nevertheless, something that today, is a given basic characteristic of modern liberal democracy. So basic, you really don’t have to spell it out. Like one person one vote. That isn’t in the Canadian Constitution either but it is a characteristic of our democracy to which few would take exception. That’s why the separation of church and state is referred to as a ‘Principle’. It is, as Jefferson noted, the most important democratic principle of all because without it, you don’t have a democracy.

Bear in mind, as well, that the separation of Church and State, which we never adopted in Canada, incidentally, does not mean the separation of faith from State, nor God from State. It simply means that the State will not legally “establish” any one particular denomination or religion as the State-sanctioned religion of political choice.

What separation intends to accomplish is the freeing of personal and religious conscience from the totalitarian temptations of State control; it does NOT mean any suppression of religious expression by those members of government duly elected.
