The 1993 amendment to the Act contained provisions for proportional value and proxy methods. Unlike job-to-job and proportional value where comparisons are made within the organization, the proxy comparison method allows organizations in the broader public sector, which have mostly female job classes, to obtain and apply pay equity information from another public sector organization.

In 1996, the government repealed the proxy comparison method with the passing of Bill 26, Savings and Restructuring Act, Schedule J. However, a legal challenge was brought against this legislation, and the Ontario Supreme Court decided that repealing the proxy method violated the Charter of Rights and Freedoms. The court declared that Schedule J had no force or effect, reinstating the proxy method in the Pay Equity Act as though it had never been repealed.
