I like the point made way down at the bottom, especially about libraries:
For readers looking to find Third Places the good news is that for now they do still exist throughout the city. However, without regular patrons that could always change. Seek out the cafes, reading rooms, and esoteric bookstores of Kensington Market. For world renowned collections of books and high speed free public Wi-Fi, one hundred Toronto Public Libraries are scattered throughout the city. For close quarters laughs many small bars host casual open-mic nights for everything from comedy to music to poetry.
Also, seems wrong to not even mention Tim's. Are Tim Hortons in Toronto not like Tim Hortons outside of Toronto? Maybe they're too small to qualify as a third place?
