What are the basic principles of democracy?
There is only one basic principle: rule by the people.
Same as most democracies: popular sovereignty, political equality, political freedom and majority rule. Look to the underpinnings of our Canadian Consitution for more traditionally Canadian aspects though: Responsible Gov't, Federalism, Judicial Review, Constitutional Monarchy, Rule of Law, and Democracy. I'd suggest reviewing Dyck's Canadian Politics: Critical Approaches as a basic starting point.
