Jim,I like the simple example of why people need to evaluate their rate of return and borrowing costs before looking at the TFSA. I am in agreement with MyviAndOwsor? with using the TFSA in conjunction with RRSP. Even if you have a defined pension it makes sense to contribute to your TFSA. My mortgage(s) rates are variable and it makes little sense to pay them down aggressively when I can take advantage of the low interest rates with some stock market investing.
