What are the important differences between mutual funds and Exchange Traded Funds (ETFs)?
The main difference between an ETF and a Mutual Fund is Management. An ETF will track a specific index with NO manager input. A Mutual Fund has a manager that is trying to choose securities for its fund based on the mandate of the fund. Liquidity ETFs trade like a stock, so you can buy at 10am and sell at 11 if you wish. Mutual Funds (most) are valued at the end of each business day, so no intraday trading.  Also ETFs are similar to stocks in that you need a buyer/seller for the ETF that you want/have. Whereas a mutual fund's units are sold back to itself. I do not know of many if any liquity issues with an ETF, but you could be stuck holding it if you can not find a buyer (usually the market maker). Mutual Funds can be closed to trading, however it is rare. Tax treatment Both come down to the underlying holdings in the fund or ETF. However, more often in Mutual Funds you could be stuck paying someone else's taxes, not true with an ETF.  For example, you buy an Equity Mutual Fund 5 years ago, you sell the fund yourself today for little to no gain. I buy the fund a month ago and the fund manager sells a bunch of the stocks they bought for it 10 years ago for a hefty gain. I have a tax liability, you do not even though it is possible that neither of us have any gains in our pocket. It can even go one step further and 6 months from now I could be down money on paper and still have a tax liability. Expenses A Mutual Fund has an MER or Management Expense Ratio, you pay it no matter what. If the fund has a positive return of 12.5% in any given year and it has an MER of 2.5%, then you are up 10%. However if the fund loses 7.5% with the same MER, you are down 10%. An ETF has a much smaller management fee (typically 0.10-0.95%) but you will have trading costs associated with any trades. Risks involved in these as well as any investment are many and likely too long to go into here. However in general, if you have a Canadian Stock ETF it will have similar risks to a Canadian Equity Mutual Fund. I hope this helps.
