Wellesley has become the fourth TTC station to offer Wi-Fi on the platforms so riders can surf and send emails on the go.

Bloor-Yonge, St. George and Bay stations are already on-line. All the Yonge-University-Spadina subway stations south of Bloor St., plus Spadina Station, are expected to have Wi-Fi by next summer in time for the Pan Am Games. Installation has already begun at College, Dundas and Union Stations.

The entire system should have Wi-Fi on the platforms and public areas by 2017 and it should be available in the tunnels by 2019, according to TTC provider BAI Canada’s Ken Ranger.

But he had no update on when the company will reach a deal with major cell providers here to enable calling and texting on transit.

“We take a long-term view on our progress with providers,” he said on Monday.

TTC buses will be Wi-Fi capable by 2016 as part of a new 95-million computer-aided dispatch automatic vehicle location system that is supposed to make surface transit more reliable.

It’s not clear if or when Wi-Fi will be made available to TTC bus and streetcar riders.
