The province is introducing a year-long pilot project that will use electronic highway signs to show drivers nearby transit information.
The signs will also promote alternative travel options in an effort to help manage congestion.
A sign will be installed on the Q-E-W near Appleby GO station on Monday displaying information about upcoming GO train departures from that station.
By the end of the year, the pilot is to expand to the Bronte and Oakville GO stations.
