Andy Byford will be on hand at the busy transfer point between 4:30 p.m. and 6 p.m. to answer queries from customers who may have been affected by the delays, which caused some passengers to be late for work and appointments. Riders were encouraged to bring their comments and concerns.
In a tweet, TTC spokesman Brad Ross wrote: "This morning's commute was horrendous. For that, the #TTC sincerely apologizes. CEO Andy Byford statement to be posted shortly."
Ross will be accompanying Byford at Bloor station.
The TTC has also confirmed that the "signal issues" that were blamed on the delays have since been cleared up and should not cause further problems into the late afternoon rush hour.
This is not the first time that Byford has apologized personally to customers for the TTC's service problems. In March, he appeared in a YouTube video shot at Bloor station to explain why a host of technical problems contributed to "a frustrating ride home" for customers.
Adding to commuter headaches Wednesday, GO Transit announced in the afternoon that all GO bus services at the Union Station bus terminal have been suspended due to a collision at Lake Shore Boulevard and BayStreet.
