Traveling from Toronto and arrive in Shanghai

I'm traveling from Toronto Monday November 13th at 6:40am and arrive in Shanghai on Tuesday November 14th at 2:05pm. I am then leaving Monday November 20th at 9:40am to Taipei Taiwan. I am eligible for the 144 hour free transit, correct? and this is done once I check in Toronto correct? And finish when I arrive there and check in the free transit counter ...? Also, Taiwan does not require a visa so I am still ok with that, since it says I need a visa for my next destination... Aside from flight/ticket information I don't need hotel information or what not?
