The Question That Follows Every Rate Decision
Every time the Bank of Canada announces a rate decision, the same question floods broker inboxes across Ontario: should I go fixed or variable? It is the single most debated mortgage decision, and most of the advice circulating online amounts to vague "it depends on your risk tolerance" commentary that helps no one.21
This guide will be more direct than that. We will break down how each rate type works mechanically, look at what history actually shows, walk through a real scenario with current numbers, and give you a framework for deciding. And yes, we will take a position on what makes sense in the spring 2026 rate environment.
How Fixed and Variable Rates Actually Work
Fixed-Rate Mortgages
A fixed-rate mortgage locks your interest rate for the full term (typically 5 years in Canada). Your rate, your payment, and the split between principal and interest are all predetermined from day one.
Here is what most borrowers do not know: fixed mortgage rates are not set by the Bank of Canada. They are driven by the bond market, specifically Government of Canada 5-year bond yields. When bond yields rise, fixed rates rise. When bond yields fall, fixed rates fall. The Bank of Canada's overnight rate has an indirect influence, but the bond market often moves independently and sometimes in the opposite direction.
This is why you can see the Bank of Canada cut its overnight rate while 5-year fixed rates stay flat or even increase. It happens more often than people expect.
Variable-Rate Mortgages
A variable-rate mortgage is directly tied to the lender's prime rate, which tracks the Bank of Canada's overnight rate almost perfectly. Your rate is expressed as prime minus a discount (or occasionally prime plus a premium). If your rate is prime minus 0.50% and prime is 4.45%, your actual rate is 3.95%.
There are two types of variable mortgages, and the distinction matters:
- Adjustable-rate mortgage (ARM): Your payment changes every time prime changes. Rate goes up, payment goes up immediately. Rate goes down, payment goes down. You always know exactly how much principal you are paying off.
- Fixed-payment variable: Your payment stays the same, but the proportion going to interest versus principal shifts. When rates rise, more of your payment goes to interest and less to principal. This is where trigger rates come from, and many Ontario borrowers experienced that pain in 2022 and 2023.
If you are choosing variable, ask your broker which type the lender offers. An ARM is more transparent. A fixed-payment variable can feel stable, but it masks what is actually happening to your amortization.
Who Has Won Historically (and Why It Matters Less Than You Think)
The most commonly cited statistic in this debate: variable rates have been cheaper than fixed rates in roughly 80% to 90% of historical 5-year terms, depending on the time period and methodology used. This number comes from a well-known study by Moshe Milevsky at York University, updated by various analysts over the years.
That statistic is real, but it requires context. "Variable won most of the time" does not mean "variable always wins" or even "variable will probably win this time." The 2020 to 2025 cycle is a perfect example:
- A borrower who locked into a 5-year fixed at 1.89% in early 2021 paid less total interest than a borrower who took variable and rode the Bank of Canada's rate from 0.25% all the way up to 5.00%.
- The variable borrower's rate was lower for the first 18 months, then dramatically higher for the next 30+ months.
Historical averages are useful background. They are not a decision-making tool for any single term. The rate environment at the time you sign matters far more than what happened over the last 30 years.
The Rate Environment Right Now: Spring 2026
As of early April 2026, the picture looks like this:
- Bank of Canada overnight rate: 2.25%, held steady at the March 18, 2026 announcement.
- Prime rate: 4.45% at most major lenders.
- 5-year fixed rates: 4.20% to 4.50% for well-qualified borrowers (insured or conventional with strong credit).
- 5-year variable rates: Approximately 3.55% to 3.95%, depending on the prime discount offered (prime minus 0.50% to prime minus 0.90%).
Unlike the past two years, variable rates now sit meaningfully below fixed rates again. The spread is roughly 30 to 70 basis points in favour of variable, which restores the traditional incentive for accepting rate risk.
What the market expects going forward: Bond markets and swap rates are pricing in the Bank of Canada holding through mid-2026, with the possibility of one or two additional 25-basis-point cuts in the second half of the year if inflation stays contained. No major institution is forecasting rate increases in 2026.
This is an opinion, not a prediction: with variable rates starting meaningfully below fixed and the likely direction of short-term rates being sideways to slightly down, variable has a clear edge on paper. You are getting a lower rate today, with further upside if the Bank of Canada cuts again, and your penalty to break the mortgage is drastically lower. More on that below.
Side-by-Side Comparison
| Dimension | Fixed Rate | Variable Rate |
|---|---|---|
| Rate basis | Government of Canada 5-year bond yields | Bank of Canada overnight rate (via prime) |
| Payment predictability | Fully predictable for the term | Adjusts with prime (ARM) or principal/interest split shifts (fixed-payment) |
| Current rate range (Apr 2026) | 4.20% - 4.50% | 3.55% - 3.95% (prime minus discount) |
| Stress test qualifying rate3 | Contract rate + 2%, or 5.25% floor | Contract rate + 2%, or 5.25% floor |
| Prepayment penalty | Higher of 3 months' interest or IRD (often $10,000 - $25,000+) | 3 months' interest only (typically $3,000 - $6,000) |
| Best when rates are... | Expected to rise significantly | Expected to hold steady or fall |
| Portability | Usually portable to a new property | Usually portable, but terms vary |
| Conversion option | N/A (already fixed) | Can convert to fixed mid-term (at posted rate) |
| Historical cost over 5-year terms | Higher total cost ~80-90% of the time | Lower total cost ~80-90% of the time |
| Psychological comfort | High -- no surprises | Low to moderate -- requires tolerance for movement |
The Penalty Problem: Where Fixed Gets Expensive
This is the section that changes minds. Most people focus on rate when choosing between fixed and variable. The bigger financial risk for many borrowers is the penalty to break the mortgage early.
Life happens. People sell homes, refinance, separate from partners, relocate for work, or consolidate debt. Mortgage Professionals Canada has estimated that roughly 60% of 5-year fixed mortgages are broken before the full term is up. Six out of ten.4
Variable penalty: simple and small
If you break a variable-rate mortgage, the penalty is 3 months' interest on the outstanding balance. On a $500,000 balance at 3.70%, that is roughly $4,625. Straightforward.
Fixed penalty: the IRD trap
If you break a fixed-rate mortgage, the lender charges the higher of 3 months' interest or the interest rate differential (IRD). The IRD is designed to compensate the lender for the interest income they lose when you break the contract early.
Here is how IRD works in simple terms: the lender takes the difference between your contract rate and the rate they can currently charge a new borrower for the remaining term, then multiplies that by your balance and the time remaining.
Example: You have a 5-year fixed at 4.50% with $480,000 remaining, and you need to break it with 2.5 years left. The lender's current 2.5-year rate is 3.80%. The differential is 0.70%. The IRD penalty is approximately $480,000 x 0.70% x 2.5 = $8,400. That is a moderate scenario. When the spread is wider -- say you locked in at 5.50% and current comparable rates have dropped to 3.50% -- that same calculation produces a penalty north of $20,000.
And it gets worse with Big Six banks, which use posted rates rather than discounted rates in their IRD calculation. This inflates the penalty significantly. Monoline lenders tend to use more reasonable calculations, which is one reason a broker might recommend them.
The bottom line: If there is any realistic chance you will sell, refinance, or restructure your mortgage before the 5-year term is up, the penalty difference between fixed and variable is a major financial consideration. In many cases, it dwarfs any rate savings.
Real Numbers: A Borrower Comparing Both Options Today
Consider a homeowner in Mississauga purchasing a property at $650,000 with 20% down ($130,000). The mortgage amount is $520,000, amortized over 25 years.
Option A: 5-year fixed at 4.35%
- Monthly payment: $2,831
- Total interest paid over 5 years: approximately $105,400
- Principal paid off after 5 years: approximately $64,500
- Remaining balance at renewal: approximately $455,500
- Penalty to break at year 3 (IRD scenario): $8,000 to $15,000+
Option B: 5-year variable at prime minus 0.75% (effective rate 3.70%)
- Starting monthly payment: $2,654
- Monthly savings versus fixed: $177
- If BoC holds for 2 years, then cuts twice (total 50 bps) for the remaining 3 years:
- Effective rate drops to 3.20% for years 3-5
- Total interest paid over 5 years: approximately $88,400
- Principal paid off after 5 years: approximately $81,500
- Interest savings versus fixed: approximately $17,000
- Penalty to break at year 3 (3 months' interest): approximately $4,300
In this scenario -- which reflects a conservative reading of where rates are likely headed -- the variable borrower saves roughly $17,000 in interest and has access to a penalty that is less than a third of the fixed penalty. If rates hold flat instead of dropping, the variable borrower still saves over $10,000 thanks to the lower starting rate. If rates rise unexpectedly by 50 basis points, the variable borrower still comes out ahead in total interest, and the penalty advantage remains intact.
The math favours variable more clearly than it has in several years. With the spread between fixed and variable restored, the interest savings are substantial even before accounting for the penalty difference.
A Risk Tolerance Framework for Choosing
Forget the generic "fixed is for conservative people, variable is for risk-takers" framing. The actual decision depends on specific, practical factors in your financial life.
Variable probably makes sense if:
- You might sell or refinance before the 5-year term is up (job change, growing family, relationship change, investment property strategy).
- You have financial margin -- your mortgage payment at a rate 1.5% higher than today would still be comfortable.
- You are disciplined enough to not panic if your payment increases for a few months.
- You understand that variable is a bet on the short end of the yield curve, and you are comfortable with that bet right now given where the Bank of Canada is in its cycle.
Fixed probably makes sense if:
- You are buying your forever home and genuinely plan to stay the full 5 years without refinancing.
- Your budget is tight and a $200 to $300 monthly payment increase would cause real stress.
- You sleep better knowing exactly what your payment is for 60 months. That psychological benefit has real value, and it is not something to dismiss.
- You are stretching to qualify and the stress test already pushed you close to your limit.
The hybrid option most people overlook
Some lenders offer split mortgages, where you divide your mortgage into a fixed portion and a variable portion. For example, 60% fixed and 40% variable on a $500,000 mortgage. You get partial payment stability with partial upside exposure, and the variable portion retains the lower penalty structure.
Split mortgages are not widely promoted because they are slightly more complex for lenders to administer. Ask your broker if this structure is available. It is a legitimate middle ground for borrowers who cannot commit fully to either side.
Our stance for spring 2026
With variable rates sitting 30 to 70 basis points below fixed, the Bank of Canada on hold, and the probability of further cuts outweighing the probability of hikes: variable has a clear edge for borrowers with financial flexibility. The rate advantage is meaningful, and the penalty advantage is substantial. For borrowers on a tight budget with no plans to move, fixed remains the safer choice, and the cost of that safety is lower than it has been in years.
The worst decision is the one made without running the numbers for your specific situation. A 15-minute conversation with a mortgage broker -- at Good Home Capital or anywhere with a licensed professional -- will give you a clearer picture than any article can.
