A Canadian equity index fund is a type of mutual fund that invests in stocks that track a Canadian equity market index, such as the S&P/TSX Composite Index or the S&P/TSX 60 Index. These indices measure the performance of the largest and most liquid companies listed on the Toronto Stock Exchange (TSX). A Canadian equity index fund aims to replicate the returns of the index it follows, before fees and expenses. Therefore, this type of fund would be best for Karen, who has a long time horizon, is comfortable with risk and volatility, and is primarily interested in growth. She also wants a mutual fund that will closely match what she sees on the TSX. References: CIBC Canadian Equity Index ETF, Top Canadian Index Funds of 2023 | The Motley Fool Canada
