Report says the pilot project intergrating GO Transit and TTC using a sticker has been a failure so far, only 134 bought so far:

The only thing that surprises me is that it looks like about 96% of the usage is for Danforth, rather than at Exhibition. So that's about 64 a month on average for Danforth.
Given that GO reports only about 250 boarding a day at Danforth, that's 26% of riders already using the pass.
Even at Exhibition the 5 people who purchased the pass represent 10% of daily ridership of 50 people.
I'm not sure how that's a failure.
Expensive? Without discounts (MDP, tax credit, etc.) that's $201.50 from Danforth, compared to $181.60 for monthly GO "pass". With an annual subscription it's $189.75 compared to $181.60. How much cheaper could you make it?
It already seems to be capturing a significant portion of the existing ridership.
There's no indication that it would capture more ridership ... but how could it given that there's no time savings at Danforth to walk from subway to GO. This is part of the reason SmartTrack is such a horrific concept in terms of downtown relief.
I'm a bit surprised though that there's 50 people willing to pay $$$ for a daily Liberty bus, but only a handful who'd use the more frequent GO.
