A market-linked GIC pays a return based on a formula tied to an index, but the return is still treated as interest income for tax purposes in a non-registered account. First calculate the index gain: 19,000 minus 13,600 equals 5,400. Divide 5,400 by 13,600 to get 39.7059%. Apply the 70% participation rate: 39.7059% × 70% = 27.7941%. Apply that return to Maya’s $5,000 investment: $5,000 × 27.7941% = $1,389.71. Because the GIC matured in the current year, that full GIC return is taxable in the year of maturity. Therefore, the correct taxable amount is $1,389.71.
