Which instrument is commonly cited as the constitutional foundation of Canada in 1867?

• A. British North America Act
• B. Canadian Charter of Rights and Freedoms
• C. Statute of Westminster 1931
• D. Constitution Act, 1867

Answer: (D)

The question tests understanding of what officially created Canada’s constitutional framework in 1867. The instrument behind Confederation is the document that brought the provinces together and established how the new federation would be governed. That is the Constitution Act, 1867 (the document was originally enacted as the British North America Act, 1867, and later renamed). It laid out the division of powers between federal and provincial governments and created Canada’s basic constitutional structure.

The other options are not the foundational instrument for Confederation: the Charter of Rights and Freedoms was adopted in 1982 and concerns rights within the framework; the Statute of Westminster 1931 granted broader legislative independence but did not establish Confederation; so they come after the 1867 foundation.
