Government of Canada Bonds are fixed income securities issued by the federal government that pay a fixed rate of interest (coupon) and return the principal amount (par value) at maturity. They are considered low risk investments, as they are backed by the full faith and credit of the government. They also provide regular income to investors, as they pay interest semi-annually. For Sheldon, who has a low risk profile and an investment objective of receiving regular income, 3% Government of Canada Bonds at par would be an appropriate investment recommendation, as they would match his time horizon of 5 years and provide him with a stable and predictable income stream. The other options are not suitable for Sheldon, as they involve higher risk, volatility, or complexity.
