Your Advisor Just Steered You Toward a 3-Year Fixed at 4.2% Instead of a 5-Year at 4.7%, Here's the Renewal Math Behind That Call
The 5-year Government of Canada bond yield sat at 3.35% in mid-May. Six weeks later it was near 3.0%, dropped by easing geopolitical tensions after the Iran peace talks made headlines. That half-point slide changed the math on every mortgage renewal conversation happening this summer.
Most advisors are now steering clients away from the 5-year fixed. The pitch is almost uniform: take the 3-year at 4.2%, ride out the current rate environment, and come back to the table in 2029 when the system has cleared the backlog from the 2020-2021 refi wave. The 5-year at 4.7% locks you in through 2031. That extra half-point spread compounds into real money, but the decision isn't actually about the rate difference right now. It's about what happens at the next renewal.
The Renewal Wave No One's Talking About
Between March 2020 and December 2021, roughly 2.1 million Canadian mortgages were originated or refinanced at rates under 2.5%. Most of those were 5-year terms. The bulk of them renew between late 2025 and end of 2026. That's now. The wave is here, and lenders are stretched. When supply tightens, pricing gets worse. The 4.7% you're seeing on a 5-year today isn't some equilibrium rate reflecting long-term bond yields and a normal spread. It's a lender managing volume by keeping the price high enough to slow inbound applications.
A 3-year term gets you out in 2029. By then, the renewal wave has passed. Lenders will be competing for your business instead of rationing it. The spread between what you pay today and what the market offers in three years is the entire bet.
Here's the dollar version. A $600,000 mortgage at 4.7% for five years costs roughly $3,384 per month. The same balance at 4.2% for three years runs $3,186. That's $198 a month, or $7,128 over three years. Not nothing, but also not the main event.
The main event is renewal number two. If you locked the 5-year at 4.7% today, you renew in 2031 at whatever the market rate is then. If you took the 3-year at 4.2%, you renew in 2029. The question is whether rates in 2029 are materially better than rates in 2031. No one knows, but the case your advisor is making is that 2029 is post-wave and 2031 is just normal market conditions. The structural distortion clears by 2029. It's already cleared by 2031, but you've paid 4.7% for five years to get there.
Why Variable Isn't Winning This Argument
Variable rates in June 2026 are sitting around 3.35%, cheaper than both the 3-year and the 5-year fixed. The spread is real. On a $600,000 mortgage, 3.35% runs about $2,995 per month. That's $191 less than the 3-year fixed and $389 less than the 5-year.
So why isn't every advisor pushing variable?
Because the Bank of Canada is at 2.25% and the direction from here is unclear. The BoC has been signaling caution since April. Inflation is running at 2.8%, above target but not alarming. The labour market is tight. If inflation ticks back up or if the U.S. Federal Reserve holds rates higher for longer, the BoC has room to hike. A 50-basis-point move puts variable at 3.85%, which is suddenly not cheaper than the 3-year fixed. Two hikes and you're at 4.35%, paying more than the 5-year for the privilege of flexibility you're not using.
The variable bet works if rates fall or stay flat. The 3-year fixed bet works if rates rise modestly or if the renewal market normalizes by 2029. The 5-year fixed bet works if rates spike hard in the next 18 months and stay elevated through 2030. Most advisors are reading the bond market and the BoC minutes and betting on normalization, not catastrophe.
What the 3-Year Gives You
It's a position. Not a hedge, not a wait-and-see. You're paying a known cost for three years and betting that the next decision point happens in a better market. If that bet is wrong and rates are higher in 2029 than they are today, you've lost the 4.7% five-year lock that was available in July 2026. If the bet is right and the market has cleared, you refinance at something closer to 3.8% and the three-year decision saves you five figures over the life of the loan.
The 5-year is the premium you pay to not think about this again until 2031.
