Service will be reduced during midday, early evening, and late evening periods due to low ridership. Service will be scheduled to operate every 30 minutes in the off-peak periods.

Schedules will also be revised, from Monday to Friday, to improve service reliability. Service levels and trip times will change throughout the day.

A new temporary service will operate in the evening, from Monday to Friday, to accommodate customer travel to the Toronto Christmas Market at the Distillery District. Buses will operate on a 121S (Union Stn-Distillery District) branch, turning back via Yonge Street, Wellington Street West, Bay Street to Front Street.
