Candiac (also designated line 14, formerly known as Delson–Candiac) is a commuter rail service in Greater Montreal, Quebec.

[3] The former Agence Métropolitaine de Transport (AMT) started service on this line on September 4, 2001, with two round trips every day.

In 2009, two additional departures were added in each direction with leased trainsets being used until new locomotives and rolling stock is received.

The line was renamed on July 1, 2010, from "Delson-Candiac" to simply "Candiac" to standardize formatting across the network.

In 2016, the study's final report rejected that option, citing longer travel times by train for people in the area.
