The Executive and Legislative powers of all three NAFTA countries share similarities and differences in their internal relationships. They are fundamentally the highest branches of government for law, policy making and many other roles that heavily influence the every day lives of their citizens. Unlike the United States and Mexico which have adapted democratic systems, Canada governs using a parliamentary style of government This is somewhat essential to the main differences of Canada's relationship between the executive and legislative branches and those relationships of the United States and Mexico. The relationships and powers between these seemingly separate branches are as distinct as the culture's of these nations. As we examine the legislative and executive branches of these nations we see how the placement and displacement of power have greatly influenced their ability to initiate change. The relationship between the executive branch and legislature often influence the decision making abilities of government and vary between the nations of NAFTA in a way that somewhat reflect their different cultures. .
Canada's parliamentary government is distinguished from the other NAFTA nations by the roles and responsibilities of the executive branch as well as the structure of the legislature. To understand the relationship between these two branches of government we first must understand their composition. The executive branch is comprised essentially of two parts. The Queen or monarch of England retains the power to appoint a Governor General who in turn appoints the other half of the executive, the Prime Minister pending the Queens consent. The Prime Minister represents the majority party in power and acts on behalf of both the crown and party. In the legislature there is again a division of power. While the House of Commons is comprised of democratically elected officials the Senate is appointed by the Prime Minister which must ultimately be approved by the Governor General.
