A replacement bus service will operate in place of the soon-to-close transit line until the new Scarborough Subway Extension comes online, currently expected for 2030.

TTC CEO Rick Leary has since released a statement on the derailment, saying, "Earlier this evening, the trailing car of a southbound train at Ellesmere Station on Line 3 Scarborough became uncoupled from the front cars and derailed."

"While we still don't know the cause of this incident, we do know there were several injuries onboard the derailed cars."

"Approximately 45 people were on the train in total and four people injured. I want to apologize to all those impacted by this incident:
and to assure our customers that safety is always paramount to all we do."

"I have spoken to my executive team and ordered an immediate review of this incident, using outside help and expertise as necessary."

"In the meantime, I have also directed that Line 3 Scarborough remains on full bus replacement until such time as we are confident it is safe to resume train service."

"I know this will be an inconvenience to our customers, but it's the right thing to do. We will share more information on this very serious incident with the public as soon as we know more."
