After two years of failed negotiations and financing difficulties, the public-private partnership between Ontario and the Union Pearson AirLink Group was called off in July 2010, and Metrolinx was handed responsibility to directly own and operate the service. Metrolinx established the new operating division that would become Union Pearson Express. The name "Air Rail Link" was used as a placeholder until the official name was unveiled on 29 November 2012.
