Tax Requirements
Precious metals, such as gold, silver, and platinum, are considered capital property under Canadian tax law when they meet specific purity and form requirements. When you sell such metals, any resulting capital gain or loss must be reported on your tax return. This is because the proceeds from the sale are considered part of your income for the year. While the sale of investment-grade precious metals (meeting purity requirements) is generally exempt from GST/HST, capital gains tax may still apply to any profit from the sale.
For further details, you can visit the CRA's guidelines on reporting capital property sales: CRA - Capital Gains
Please note that payment will not be issued until your we receive a copy of your SIN.
