Canadian intergovernmental relations are complicated by many factors, including the division of powers between the federal and provincial governments. It is well known that the Constitution Act, 1867 defines the powers and jurisdiction of the federal and provincial governments. For the Constitution to be upheld and upheld, a national court was needed. Prime Minister Alexander Mackenzie and Parliament passed the Supreme Court Act which created a final Canadian court of appeal and the Supreme Court of Canada consisting of a Chief Justice and five Puisne Justices (Iacobucci, 28) . However, the number of Supreme Court judges increased to nine, including the Chief Justice. Judges are chosen from across Canada “so that they bring to the Court a rich diversity of experience and understanding” (Iacobucci, 32). The functions of the Supreme Court of Canada include interpretation of the Constitution, including the Canadian Charter of Rights and Freedoms, judicial review, and determining the distribution of powers between the federal and provincial governments. The Supreme Court of Canada played an important role in determining the sharing of powers between the federal and provincial governments. therefore, made Canada what it is today. The role of the Supreme Court of Canada has changed throughout history, having different effects on the Canadian government. The Supreme Court's interpretation of the distribution of powers between the federal and provincial governments has changed considerably thanks to the Judicial Committee of the Privy Council, the peace, order and good government clause, the inabilities of the provinces and the Canadian Charter of Rights and Freedoms.Previous in the middle of the document ......fr introduced with new jurisdictional questions such as the environmental question which were not their main concern before. Furthermore, with the introduction of the Canadian Charter of Rights and Freedoms, the way in which the Supreme Court interprets the division of powers has changed again, because it must take into account a new factor. Recently, the role of the Court has not been as important as it was in the 19th and 20th centuries in determining the division of powers between the two levels of government. This is because the provinces and the federal government do not like the winner-takes-all system in the courts, even though they have relatively tried to remain balanced in decision-making today. Overall, the evolving role of the Supreme Court of Canada in the distribution of powers between the federal and provincial governments has played an important role in the way Canada functions today..
