Public Works and Government Services Canada (PWGSC) was created in 1993 through the amalgamation of the former Government Telecommunications Agency (Communications Canada), Public Works Canada (PWC), Supply and Services Canada (SSC), and the Translation Bureau (Secretary of State of Canada).

Following the government's decision to review the way in which corporate communications will be delivered, on April 1, 2004, PWGSC assumed some of Communication Canada's functions.

The Office of the Procurement Ombudsman, an independent Office, and part of the portfolio of the Minister of Public Works and Government Services Canada,was established on May 15, 2008, as one of the final steps in the implementation of the Federal Accountability Act.
