The phrase Common Sense Revolution (CSR) has been used as a political slogan to describe conservative platforms with a main goal of reducing taxes while balancing the budget by reducing the size and role of government. It has been used in places such as  Australia and the U.S. state of New Jersey in the 1990s. This article deals with the "Common Sense Revolution" as it was under Ontario Premier Mike Harris, and the Progressive Conservative Party of Ontario from 1995 to 2002.
