For Tutu, you don't need care what kind of investment, the only 2 things for you, are the return and risk. I can tell you, return is not higher comparing to the 5 years term, ricky is almost 0%. However, you can take adventage of the your income dedut for Ontario provincial tax.
For Xiang
you can sell your Bond as you like like stock. I don't recommend this bond if you want to invest your money, because the rate is not high with 5 years term. Even you can find some 1 year term bond over 5% return. From my oppinion, $5000 is your minimum purchasing amount usually. And other point, it is only dedutable income for Ontario provincial tax. You still need to pay federat tax.
