Reduced service on GO trains and buses and the UP Express will start on Wednesday, March 18.
Ridership has fallen about 40 per cent across the network since January according to Metrolinx.
The decline is expected to continue due to COVID-19 and what that means such as school closures, event cancellations and more people working from home.
The March break vacation will also have an impact on numbers.
“Our key consideration is ensuring our services can continue and our employees and customers are safe,” said Metrolinx President and CEO Phil Verster. “We want to ensure there is a reliable and sustainable plan for service to continue over the weeks to come.”
“GO and UP Express are vital to our region,” Verster said. “Every route we serve, we will continue to serve.”
Normally, there are seven southbound trains between Barrie and Toronto weekday mornings and seven return trips northbound at the end of the work day.
This will be reduced to five trains in both directions starting Wednesday.
There is no change to weekend train service on the route.
