> i would like to open an account in some canadian bank,and would you be so kind to inform me:

> 1.is there canadian bank service in china

Yes. e.g. Royal Bank. But these banks are more like seperate banks from their Canadian entities. It's said that the account of Canadian bank in China couldn't be transferred to Canada. You'd better make a phone call to the bank office.

> 2.will i be charged tax for my deposit once i transfer money to my bank account.

No.

> 3.will any money transfered from mainland after my landing be charged income tax.

If the money is your income from China after you immigrate to Canada, you may pay tax for that part. If the money is your income before you go to Canada, it's tax free.
