In Canada all laws the legislature passes have to be approved by the monarch or the monarch's representative.

In Canada the monarch is the judicial branch. Ministers are appointed and dismissed by the monarch. Parliament can be adjourned by the monarch.

Again, so?

When was they last time these things weren't rubber stamped?

What do you suppose would happen should the symbolic monarch not rubber stamp procedure?

Why is it that Canada, et al are regarded in the world as "full democracies" whereas the US is ramked a bit lower as a "flawed democracy"?
