For the cost of $3.50 (price goes up to $7 in June 2009), you can get OPUS, a smart card in circulation since Spring 2008 with comparable transit technology as that in San Francisco and Paris. Commuters can stock up with the fare plan of their choice and reuse the card up to seven years. STM will eventually phase out all non-OPUS passes and tickets but residents can still opt for old-fashion fare passes and tickets, at least for now.
