What type of investments should be in a TFSA, given its tax-free growth and withdrawal benefits?
A questoin that I deal with almost every day.  Like most investments it comes down to.....What is the purpose for this money?  If it is truly a rainy day savings account that you may need in the short term, then fixed income investments like savings accounts, GIC's, Bonds, Bond funds and Fixed Income ETF's are ideal as they are taxed very inefficiently outside of any registered plan (therefore tax free in here).  However if you have a plan in place that has all your short term needs covered elsewhere, I believe this is the place that you should be the most aggressive in your overall portfolio.  If that mining stock goes up by 1000% wouldn't it be nice to put all of that gain in your pocket?
