TORONTO, Ont. – Metrolinx has signed an agreement with the TTC to roll out Presto fare cards in all subway stations, buses and streetcars, but the cards will not be in effect until 2016.

Ontario Transportation Minister Bob Chiarelli said more than 400,000 people use Presto cards across the greater Toronto and Hamilton area.

“Canada’s busiest transit hub will now have the fully integrated fare payment method, from Hamilton to Barrie to Peterborough, and will include the province’s largest public transit provider – the TTC,” he announced, Wednesday.

“When Presto first hit the market, there were 4,200 fare card stations. After a year, that figure had increased to 48,000. Today, more than 400,000 people are using a Presto card in the GTA chain, and we are signing up an average of 22,000 new Presto users per month,” he said.

A total of eight municipal transit systems will be covered by Presto.

Chiarelli said it’s not only a convenience for riders, but also a money-saver — noting the TTC will save $10-million a use with Presto.

The TTC has also formally signed an agreement with Metrolinx formalizing construction and future operation of the four new light-rail lines being built in Toronto, which will be owned by Metrolinx and operated by the TTC.

One of those lines includes the Eglinton-Crosstown LRT, from Black Creek to Kennedy, which is expected to be complete by 2020.
