On November 20th, 2019, OC Transpo announced that they are adding 20 dedicated buses that will be on standby during peak periods to support R1 bus replacement service, when needed. These dedicated buses will ensure that OC Transpo can implement R1 bus replacement service without impacting transit reliability across the system.
These 20 new buses will be in service the first week of December.
A copy of the O-Train Line 1 and Bus Service Update presentation is available on the O-Line Blog.
