I have about $10,000 that I want to invest for about 3-4 months. I was wondering if it would be better to put it in a TFSA account for that long or to purchase a T-bill with the money. I have room for $10,000 in my TFSA account. I will need the money at the end of the 4 months. The TD TFSA gives an annualized R.O.R of 1.25%.
