Regular TTC subway service has resumed on the downtown portion of Line 1 following a police investigation. Police and paramedics initially responded to St. Andrew Station around 4:12 p.m. In a social media post, the TTC said crews were responding to an injury on the tracks. As a result, subway service was halted between St. George and College Station during the afternoon rush. Police said there is no threat to public safety. Service resumed around 5:30 p.m., but a subsequent medical emergency resulted in another service disruption between St. George and St. Andrew Stations. Subway service returned to normal just after 6:30 p.m.
