British North America Acts
Section 52(2) of the "Constitution Act, 1982" says "The Constitution of Canada includes (a) the "Canada Act 1982", including this Act; (b) the Acts and orders referred to in the schedule; and (c) any amendment to any Act or order referred to in paragraph (a) or (b)." The schedule, in turn, lists the following documents. Most were British North America Acts and were renamed as Constitution Acts in 1982. Others include the "Parliament of Canada Act, 1875", the "Statute of Westminster, 1931", and acts that created new provinces or changed provincial borders.
