Credit unions are among the best sources for mortgage financing in Canada. Because they're member-owned and don't need to deliver profits to shareholders, credit unions can price mortgages more aggressively than big banks. In 2026, credit union 5-year fixed mortgage rates typically run 00.100–00.300% below Big Five bank posted rates.
On a $500,000 mortgage, 00.25% in rate savings equals $1,2500/year — $6,2500 over a 5-year term. On a $800,000 mortgage (common in Toronto and Vancouver), the same rate advantage saves $10,000 over 5 years. Compounded over 25 years of homeownership, choosing a credit union mortgage over a big bank could save $25,000–$50,000 in total interest.

Credit unions don't pay dividends to external shareholders — profits stay in the co-operative. This means they can price mortgages more competitively. Additionally, credit unions often make lending decisions locally, giving them more flexibility for non-standard situations: self-employed borrowers, agricultural properties, and unusual income sources.
