Nope, totally different technologies. You can no more get a Presto card to work with a normal TTC turnstile than you can get a key to open a combination lock.
---Explanation---
(I may in fact be oversimplifying... there could, for instance, be separate identifiers for adult metropasses versus the discounted ones that get logged by the turnstiles for statistical purposes, and rather than a monthly code that needs to be changed, the turnstiles might have an automatic internal calendar that checks against a date written into the card's strip, which would presumably cut down on the amount of physical fiddling with them. AFAIK the TTC doesn't ever really talk about the precise functionality of this stuff, for obviousish reasons.)[/I]
