Peak period service on the 53A (Finch Station-Staines) branch will be scheduled until express service returns system-wide, to serve areas east of Markham Road, where scheduled 953A STEELES EXPRESS service was temporarily suspended due to the COVID-19 pandemic. The 53A service will operate every 18 minutes during peak periods.

Service will also be reduced on this route to reallocate resources to other busier routes. Late evening service will be reduced from every 10 minutes to every 12 minutes.
