Why do we say the canadian constitution is made up of many parts???

The Constitution of Canada (French: Constitution du Canada) is the supreme law in Canada.[1] It outlines Canada's system of government and the civil and human rights of those who are citizens of Canada and non-citizens in Canada.[2] Its contents are an amalgamation of various codified acts, treaties between the Crown and indigenous peoples (both historical and modern), uncodified traditions and conventions. Canada is one of the oldest constitutional monarchies in the world.[3]

According to subsection 52(2) of the Constitution Act, 1982, the Canadian Constitution consists of the Canada Act 1982 (which includes the Constitution Act, 1982), acts and orders referred to in its schedule (including in particular the Constitution Act, 1867, formerly the British North America Act, 1867), and any amendments to these documents.[4] The Supreme Court of Canada has held that the list is not exhaustive and also includes a number of pre-confederation acts and unwritten components as well.[5] See list of Canadian constitutional documents for details
