Canada is a constitutional monarchy and a parliamentary system. A significant difference between Canadian and Australian government is that Canada has an appointed Senate unlike Australia's which is elected. The Governor-General appoints the Canadian Senate from recommendations by the Prime Minister. Canada is a federal system and has a bill of rights known as the Charter of Rights and Freedoms. This is entrenched into the Canadian Constitution of 1982. Canada has had a bill of rights since 1960, however, prior to the Charter of Rights and Freedoms it was a statutorial act, not a constitutional one.

That graph is from a 1998 Newspoll which asked those polled if they had to choose from the three models which would be their choice; direct election, parliamentary appointment after election within parliament and a council composed of judges and former governor-generals appointing the head of state. I am not surprised that the natural Australian instincts for democratism won out. (more)
