I will arrive PVG on 14:10 at T2 from Vancouner. Need to catch flight dispatching 16:05 at T1.

Well, is it international to domestic transfer at PVG? If yes, your time is a little bit tight. Although there is a special passageway, you still need to complete those transfer procedures step by step. However, if you purchase the interline tickets, you will catch the next flight. Thus you are advised to consult your airline again.
