Hi, Linu, Congratulation !!
1. You don't need to write POF on B4, “ If you are entering or leaving Canada and are carrying $10,000 or more including any combination of coins, domestic or foreign bank notes, and securities, such as travellers cheques, stocks and bonds, you have to complete
Form E677 (PDF, 41 KB), Cross-Border Currency or Monetary Instruments Report – Individual.”
2. Yes. This form is available in flight and at airport, however, if you need to fill in advance you can fill out this PDF form and keep print out with you. http://www.cbsa-asfc.gc.ca/publications/forms-formulaires/e677.pdf
3. You have to write the Description of all goods (include serial numbers, if applicable), Gold jewellery items should be specified on B4 form.
4. Example: Gold 4 ring, 2 chains, 4 bangles, and 4 ear rings etc... (80 gram – approximately).... Total value ...... $ .... CAD.
