What Is MER and Why Does It Matter So Much?
The Management Expense Ratio (MER) is the annual percentage of your fund's assets deducted to cover management fees, operating costs, and in some cases, trailing commissions paid to financial advisors. It's charged invisibly — you never write a cheque. Instead, your fund's daily unit price is reduced to reflect the fee.
A fund returning 7% gross with a 2% MER delivers a 5% net return to you. The fund manager earns their fee whether the market goes up or down. That 2% doesn't sound like much — but it compounds against you just as powerfully as returns compound for you.

Why Index ETFs Win Long-Term
Decades of academic research — from William Sharpe's arithmetic of active management to SPIVA Canada's annual fund scorecards — consistently shows that after fees, fewer than 20% of actively managed funds outperform their benchmark index over a 15-year period. The MER is the primary reason. When you pay 2% for underperformance, the math compounds against you relentlessly.
