The Candiac line is a commuter railway line in Greater Montreal, Quebec, Canada. It is operated by the Agence métropolitaine de transport (AMT), the umbrella organization that plans, integrates, and coordinates public transport services across this region.
The Candiac Line was originally operated by the Canadian Pacific Railway (CPR) between 1887 and 1980. The AMT resumed passenger service on this line in 2001.
There are 9 inbound and 9 outbound trains each weekday. 
The line offers nine departures every weekday towards Montreal and nine return trips to Candiac every weekday. Most departures are during rush hour, but three are offered during off-peak hours in each direction.
Service started on September 4, 2001 with 2 round trips every day. One trainset was used for both departures. In September 2003, service was increased to 4 round trips per day and a second trainset was used. Service was extended to Candiac in 2005. In 2009, two additional departures were added in each direction with leased trainsets being used until new locomotives and rolling stock is received.
Service on the line was suspended from February 17, 2006 to March 9, 2006 after the derailment of 6 Canadian Pacific freight cars on February 17. The freight cars derailed on a bridge used by the train service. This was one of the longest disruptions in train service for the AMT.
The line was renamed on July 1, 2010 from "Delson-Candiac" to simply "Candiac" to standardize formatting across the network.
- Improve railway infrastructure on the Adirondack/Lacolle subdivision. The $20-million project includes improving signaling, adding a siding for freight trains, refurbishing switches and improving pedestrian crossings. Work should be completed by 2014.
- Extending the line to Saint-Jean-sur-Richelieu. A study on the projet will start in 2014.
- Build a new train station named Du Canal in Lachine along Saint-Joseph Boulevard. This project is part of the MTQ's mitigation measures for the reconstruction of the Turcot interchange. The new station is expected in 2016.
- Build a new layover facility (overnight service and storage yard) at the end of the line. Construction is linked to the railway improvement project above.
