The 3-year fixed mortgage is one of Canada's less-discussed but genuinely useful mortgage products. It gives you rate certainty for a shorter window than the dominant 5-year term, making it attractive when you expect rates to fall in the medium term or when your life circumstances may change within 3-4 years.
Rates are for illustrative purposes. Contact a mortgage broker for your actual qualifying rate.
What Is a 3-Year Fixed Mortgage?
A 3-year fixed mortgage locks in your interest rate for a 3-year term. Your payments stay the same throughout, giving you budget certainty. After 3 years, you renew at whatever rates are available — which could be higher or lower than today.
In Canada, mortgages are typically amortized over 25 years (or up to 30 years for insured mortgages on new builds), but the term — the period your rate is fixed — is much shorter. The 5-year term dominates Canadian mortgage lending, but 3-year terms represent a significant share of new originations when borrowers expect rate movement.
3-Year Fixed vs. 5-Year Fixed: Key Differences
| Feature | 3-Year Fixed | 5-Year Fixed |
|---|---|---|
| Rate certainty | 3 years | 5 years |
| Typical rate premium | Often 0.10-0.30% lower | Base benchmark |
| Renewal frequency | More often (every 3 yrs) | Every 5 years |
| IRD penalty exposure | Less time at risk | More time at risk |
| Flexibility | Higher (sooner renewal) | Lower (locked longer) |
| Best for | Expecting rate drops | Wanting maximum certainty |
Pros and Cons of a 3-Year Fixed
Pros
- Rate certainty for 3 years — stable payments
- Often slightly lower rate than 5-year
- Shorter commitment — renew sooner if rates drop
- Smaller IRD penalty exposure if you break early
- Good if you plan to sell or refinance in 3-4 years
Cons
- Renew more frequently — administrative burden
- Rate risk at renewal — could be higher
- Less certainty than 5-year in volatile environments
- Fewer lenders offer competitive 3-year rates
When Does a 3-Year Fixed Make Sense?
A 3-year fixed is typically the right choice in a few scenarios:
- You expect rates to fall: If economists and the Bank of Canada are signaling rate cuts, locking in for 3 years lets you re-access lower rates sooner than a 5-year would.
- You're planning a life change: Expecting to sell, upgrade, or move within 4-5 years? A 3-year term means you may be at renewal right when you need flexibility.
- You want less IRD exposure: The shorter the remaining term on your mortgage, the smaller the Interest Rate Differential (IRD) penalty if you need to break it. Three years provides meaningful protection here.
- The rate spread is attractive: When 3-year rates are materially lower than 5-year rates (more than 0.20%), the math often favors going shorter.
Breaking a 3-Year Fixed Mortgage
Like all closed fixed-rate mortgages in Canada, breaking a 3-year fixed before the term ends triggers a prepayment penalty. This is calculated as the greater of:
- 3 months' interest on the outstanding balance
- Interest Rate Differential (IRD) — the difference between your contract rate and the lender's current posted rate for the remaining term, multiplied by the balance and time remaining
With a 3-year term, if you break in year 1 you face a full IRD calculation. If you break in year 2 or 3, the remaining time is shorter, which reduces the penalty. This is one genuine advantage over a 5-year term where penalties can be substantial.
3-Year Fixed Mortgage Rates: What Drives Them?
Three-year fixed mortgage rates in Canada are primarily benchmarked against the 3-year Government of Canada bond yield. When bond yields rise, fixed mortgage rates rise. When they fall, lenders typically pass on some — but not all — of the reduction with a lag.
Lenders also factor in their cost of funds, competitive positioning, and posted rate spreads (which affect penalty calculations). Major banks typically offer higher 3-year fixed rates than the discount market — mortgage brokers can usually access rates 0.40-0.70% lower than posted rates.
Renewing a 3-Year Fixed Mortgage
Renewal is straightforward: about 4-6 months before your maturity date, your lender will send a renewal offer. You are under no obligation to accept — you can shop the market, use a broker, or switch lenders entirely (subject to a standard re-qualification if switching). Switching lenders at renewal does not typically trigger a penalty if you wait until maturity.
Key renewal tips:
- Start shopping 4 months before maturity — many lenders honor rates secured early
- Don't just accept your current lender's first offer
- Consider whether a variable rate makes sense at renewal
- Check if you want to take out additional funds at renewal (refinance)
3-Year Fixed vs. Variable Rate
The eternal Canadian mortgage debate: fix or float? With a 3-year fixed, you get certainty at a slightly higher initial rate. With a variable rate mortgage, you expose yourself to rate movements — but historically, variable rates have come out ahead over full economic cycles.
In a declining rate environment, variable rates capture every Bank of Canada cut automatically. In a rising environment, fixed provides a meaningful shield. The 3-year fixed is often a comfortable middle ground — not as exposed as a 5-year in a rate-falling scenario, not as volatile as variable.

Most major banks and credit unions offer 3-year fixed terms, but the competitiveness varies. Monoline lenders (accessible through mortgage brokers) often have the best 3-year fixed rates on the market.
Yes. Most Canadian mortgages allow annual prepayment privileges of 10-20% of the original balance, plus the ability to increase your regular payment by 10-20%. These privileges reset each year and do not trigger penalties.
You enter a renewal period. You can stay with your current lender, switch to a new lender without penalty, or negotiate a new rate and term. You are not forced into any particular product.
Yes. If your purchase meets CMHC/Sagen/Canada Guaranty criteria (purchase price under $1.5M, less than 20% down), a 3-year fixed can be insured, which often unlocks lower rates.
