The TTC has produced a map outlining changes to its Sunday subway service.

Nearly a week after launching its new Sunday schedule, TTC spokesperson Brad Ross posted the map on Twitter, which shows the exact times that trains leave major stations.

Prior to Jan. 3, the first subway trains left at approximately 9 a.m. Now, service begins an hour earlier with the first trains leaving around 8.

However, the 8 a.m. start-time is approximate, so the new map breaks down specific times by station, so those who rely on transit can time their journeys to the minute.

For example, the first southbound train from Downsview Station leaves at 8:02 a.m., while the first southbound train from Finch Station leaves at 7:55 a.m.

Those using Dundas West Station can expect the first eastbound train to leave at 8:14 a.m., while those travelling westbound from Dundas West will be picked up at 8:21.

Schedules for stations not listed on the map can be found online, by selecting the subway line and station name.
