I don't actually live in Toronto, but are you guys still trucking your garbage off to Michigan? That still makes me scratch my head...And Toronto is also the city known for taking recyclables and combining them with garbage and tossing it all in the dump which is in someone else's community.
As for dog poop etc... There will be a need for plastic bags for some time, until there are viable alternatives. Scooping poop into a paper bag isn't going to cut it. Putting it in your pocket isn't going to work either. This is one of the advantages of the ban... "Somebody" out there will come out with an alternative that is environmentally sound, just like someone will eventually come up with an alternative to gas-burning engines. It's inevitable...
