renew the passport as soon as possible
Due to the new passport law of China, the passport will not be renewed after Jan. 1, 2007, So you have to renew your passport as soon as possible. The embrassy of China in Canada can renew your passport 18 months in advance ( the former policy is 12 months in advance). So if your passport will be expired in 18 months, you have to extend it asap, otherwise you have to fly to Ottawa for a new passport.
