Service was extended beyond Georgetown to Guelph on October 29, 1990, but was again cut back to Georgetown on July 2, 1993.<ref name=transittoronto/>

Limited weekday midday service was introduced in April 2002, with four trains in each direction between Union and Bramalea.  These trains were discontinued in 2011 to facilitate construction of the Georgetown South Expansion project.

On December 19, 2011, the Georgetown Line was renamed the Kitchener Line as service was extended to [[Kitchener railway station|Kitchener]], making one intermediate stop at [[Guelph Central Station|Guelph]]. Another intermediate stop, [[Acton GO Station|Acton]], opened on January 7, 2013.<ref name=transittoronto/>

Weekday midday service was re-introduced in September 2015, with hourly service between Mount Pleasant and Union.<ref name=TheStar-2015-08-19>{{cite web
