Route 46 was created in May 2008 to connect Churchill Meadows to the Erin Mills Town Centre when the usual routes 41 - Thomas and 49 - McDowell are diverted to Streetsville, and to provide a faster alternative to the 32 - Lisgar GO for those living along Tenth Line. In October 2016, it was removed from Lisgar GO and Tenth Line north of Britannia and rerouted through central Lisgar to replace the western end of route 10 - Bristol-Britannia, leaving Route 32 as the only connection between Lisgar and its GO station. At the same time, it was extended east from Erin Mills Town Centre to the transitway station, as a replacement for part of the 109 - Meadowvale Express.
