Sure! There’s nothing stopping you, but we wouldn’t necessarily recommend it. The money will grow tax-free and withdrawals are free. The only thing you need to keep in mind is the contribution limit. If you withdraw from the account, you won’t be able to add the withdrawn funds back into your TFSA again until next year. As long as you’re able to stay within the contribution limits, there’s no reason why a TFSA can’t hold your emergency fund. However, TFSAs are usually used in conjunction with RRSPs to create a retirement fund or to save for another big purchase down the line. Words to the wise: it’s probably best to keep emergency funds in cash savings rather than in investments, since you want to be able to access your money whenever you need it and not face the possibility of withdrawing during a market dip. You could consider putting your emergency fund in a savings account and use your TFSA for longer-term savings goals.
