What type of construction work is happening?   

This weekend, we're working to transform your line to enable future two-way, all-day service as well as access to new stations and transit connections on your line. This will mean more trains, more often – from Stouffville to Markham, Scarborough, and Toronto. Learn more about how we're working to transform service on your line.
