Last week, BAI Canada and the TTC brought free Wi-Fi service for TTC passengers to Castle Frank, Sherbourne, Bathurst and Christie stations.

Wi-Fi service is now available to passengers at all 1 Yonge - University line stations south of Bloor Street and 2 Bloor - Danforth line stations between Castle Frank and Christie stations.

BAI Canada also confirmed its commitment to a fully rolling out a Wi-Fi and cellular network across the subway system over the next 20 years, with plans to bring 25 more stations online by the end of next summer. It intends to complete all stations by early 2017. BAI Canada continues to work with WIND Mobile to extend cellular service into more stations.

Each station hosts the TCONNECT Wi-Fi service to connect transit riders and let the TTC use business and transit applications, such as digital signage, for its passenger information services.

The partners launched the service at Bloor-Yonge and St. George stations in December 2013, expanded it to Bay Station in August, 2014, to Wellesley Station in September, 2014 and to College Station, also in September, 2014. They added Dundas, Queen, King and Union stations to the network in November, 2014. They connected Queen’s Park and Museum stations and Spadina Station earlier this year. (And, they also seem to have quietly added St. Andrew and Osgoode stations to the list, too.)

TCONNECT is ad-supported, meaning advertisers sponsor the Wi-Fi service with short ads. The service comes at no cost — no cost for passengers to sign onto the network and no cost to the TTC, passengers or Toronto taxpayers for installing the infrastructure. (In fact, it generates revenue for the TTC.)
