Mutual Fund
Fonds commun de placement in French
Quick definition
A mutual fund pools money from many investors into a single professionally managed portfolio of stocks, bonds or other assets. You buy and sell units directly with the fund company at the day's net asset value, usually through an advisor, a bank branch or online.
How a mutual fund works
A mutual fund takes contributions from thousands of investors, pools them, and hands the pot to a professional manager who buys a portfolio of stocks, bonds or both. Even a $100 contribution buys you a slice of every holding in the fund, which is the core appeal: instant diversification and professional management without needing a large sum or any investing knowledge.
Mutual funds are priced once per day. After markets close, the fund adds up the value of everything it owns, subtracts liabilities, and divides by the number of units outstanding to get the NAV, or net asset value per unit. Every purchase and sale order placed that day fills at that single price. There is no intraday trading and no bid or ask; you deal directly with the fund company.
You can buy mutual funds through a financial advisor, at a bank branch, through a discount brokerage, or directly from some fund companies, often with automatic monthly contributions taken straight from your chequing account.
Trust units and distributions
Most Canadian mutual funds are structured as trusts, so what you own are units of the trust. The fund itself pays little or no tax; instead, the interest, dividends and realized capital gains it earns are flowed out to unitholders as distributions, usually monthly, quarterly or annually. In a non-registered account, those distributions are taxable to you in the year they are paid, even if they are automatically reinvested in more units and you never see the cash. Inside a TFSA or RRSP, distributions have no immediate tax consequences.
This creates the classic year-end distribution surprise. Many funds pay out the capital gains they realized all year in one December distribution. Buy the fund in late November in a taxable account and you can receive, and pay tax on, a distribution of gains that built up long before you arrived. Checking a fund's estimated year-end distribution before a large taxable purchase in the fall is a small habit that avoids a needless tax bill.
The series alphabet soup
The same portfolio is often sold in several series, each with different fees baked in. The three worth knowing:
- Series A: the traditional advisor-sold version. Its fee includes a trailing commission paid to the advisor's firm every year you hold the fund.
- Series F: for fee-based accounts where you pay the advisor directly. The trailing commission is stripped out, so the fund's own fee is much lower.
- Series D: for discount brokerages, with a reduced trailer reflecting that no advice is provided.
The fee problem
The main criticism of Canadian mutual funds is cost. The average fees on Canadian equity mutual funds are among the highest in the developed world, with actively managed funds commonly charging around 2% per year (as of July 2026), quietly deducted before you see any return. The full mechanics, and what those percentages cost in dollars over decades, are covered in our MER article; the short version is that a 2% annual fee can consume a third or more of your final portfolio over an investing lifetime.
When mutual funds still make sense
For all the fee criticism, mutual funds keep some genuine advantages. You can set up automatic contributions of $25 or $50 a month with no commissions, which makes them excellent for building the savings habit. Purchases and sales are commission-free in dollar amounts, with no need to think about share prices or market orders. Workplace group RRSPs and payroll savings plans are almost always built on mutual funds, often with employer matching that outweighs any fee concern. And for people who simply will not open a brokerage account, a low-cost index mutual fund bought at the bank beats not investing at all.
Mutual fund vs ETF
The ETF is the mutual fund's main competitor, and the practical differences come down to how you buy and what you pay.
| Mutual fund | ETF | |
|---|---|---|
| Pricing | Once daily at NAV | All day at market prices |
| Typical fees | Around 2% for active funds, roughly 1% for index versions | About 0.05% to 0.25% for index ETFs |
| Minimum investment | Often $500, or $25 with automatic plans | The price of one unit, sometimes fractional |
| How you buy | Advisor, bank branch or fund company | Self-directed brokerage account |
In Canada
The mutual fund remains the dominant retail investment vehicle in Canada, with trillions of dollars in assets (as of July 2026), far more than any other fund type. Most of that money arrived through bank branches and advisor networks rather than self-directed accounts, which is why the typical Canadian investor owns bank mutual funds without ever having compared alternatives.
Regulation has been tightening around how funds are sold. Deferred sales charges, which once penalized investors for selling within several years of buying, are banned on new purchases, and trailing commissions can no longer be paid to discount brokerages that provide no advice (as of July 2026). Every fund must also publish a plain-language Fund Facts document showing its fees, risks and past performance before you buy.
Worked example
Nadia holds $30,000 of an equity mutual fund in a non-registered account. In December, the fund pays a distribution of 4%, or $1,200, which is automatically reinvested in new units. She receives no cash, but she does receive a tax slip and owes tax on the $1,200 for the year. Her friend holding the identical fund inside a TFSA receives the same reinvested distribution and owes nothing. The reinvested amount does increase Nadia's adjusted cost base, so she will not be taxed on it twice, but the annual tax drag is real money that registered accounts avoid entirely.
