Most lenders let you lock a renewal rate before your mortgage actually matures, using a rate hold, a written commitment to a specific rate for a set number of days. The common range across lenders is roughly 30 to 120 days, though the exact window varies by lender and by whether you are renewing, switching, or buying.
Locking in early protects you from a rate increase between now and maturity. Waiting keeps your options open if rates move in your favour. The right call depends on your lender’s rate hold length, whether that hold includes a float-down clause, and how much certainty you want.
Pekoe Mortgages is a licensed brokerage in Ontario (FSRA Licence #13321) and Alberta (RECA licensed). We hold rates across many lenders at once, which is one of the reasons this decision looks different working with a broker than calling a single bank.
What Is a Mortgage Rate Hold?
A rate hold is a lender’s written promise to honour a specific interest rate for a fixed number of days, even if the posted rate moves before your mortgage closes or renews. Rate holds are free and do not obligate you to proceed with that lender. Most Canadian lenders offer holds somewhere in the 30 to 120 day range, and the exact length is set lender by lender.
For a purchase, the rate hold covers the gap between your offer and closing. For a renewal, the rate hold covers the gap between the day you request a rate and your maturity date, the pre-maturity window. Some lenders extend renewal-specific holds further than their standard purchase hold, but the exact number is never guaranteed until you confirm it in writing with that lender.
A rate hold is a locked ceiling on your rate for a defined number of days before your mortgage matures or closes, and the length varies by lender.
What Does a Float-Down Clause Do?
A float-down clause lets you take a lower rate if the market rate drops after you lock your hold, instead of being stuck at the higher rate you held. Not every lender offers this feature, and some attach conditions, extra paperwork, or restrict it to certain products. Where it exists, it typically works one way: your rate can move down before you sign, but it cannot move up past what you held.
Without a float-down clause, a standard rate hold works the other direction only. You are protected if rates rise, but you do not automatically benefit if rates fall, you would need to ask the lender to requote or switch lenders instead. Whether a specific lender offers float-down, and under what conditions, varies and should be confirmed before you commit to a hold.
A float-down clause is the feature that turns a rate hold from a one-way ceiling into a two-way benefit, and availability depends entirely on the lender.
Renew Early or Wait? The Decision Table
There is no single correct answer, because it depends on your own risk tolerance and your lender’s terms. The table below breaks down the situations where locking in early tends to make sense against the situations where waiting closer to maturity tends to make sense.
| Consideration | Renew early makes sense if | Waiting makes sense if |
|---|---|---|
| Certainty vs flexibility | You want a fixed number to budget against now and dislike rate uncertainty | You are comfortable monitoring the market and can act quickly if a better rate appears |
| Float-down availability | Your lender offers a float-down, so locking early costs you nothing if rates fall later | Your lender does not offer float-down, so an early lock could leave you stuck above a later, lower rate |
| Time to maturity | You are inside the rate hold window and a competitive rate is available today | Maturity is still months away and outside every lender’s hold window, so there is nothing to lock yet |
| Life plans | You plan to keep the mortgage for the full new term and want a known payment | You may sell, port, or restructure before the term is out, so locking in early adds little value |
| Negotiating power | You already have a written competing offer and want to secure it before it expires | You have not yet shopped the market and want time to compare lenders first |
If your lender offers a genuine float-down and you are inside the hold window, locking early carries almost no downside. Without a float-down, an early lock is a bet that today’s rate will look good compared to maturity day.
How the Pre-Maturity Window Actually Works
The pre-maturity window opens when your lender first allows you to request a renewal rate hold, and it closes on your maturity date. Inside that window, you can typically request a rate quote, compare it against other lenders, and decide whether to lock. Outside the window, most lenders will not yet quote a renewal rate because market conditions can shift too much before maturity.
| Scenario | Typical rate hold window (varies by lender) |
|---|---|
| Purchase mortgage | Roughly 30 to 120 days |
| Switching lenders at renewal | Roughly 30 to 120 days |
| Same-lender renewal | Roughly 30 to 120 days, some lenders extend renewal-specific holds further |
Once you are inside the window, this is also the point where it makes sense to negotiate your renewal rate rather than accept the first number your current lender sends. A written rate hold from a competing lender is one of the strongest negotiating tools you have, because it forces your existing lender to match or lose the file.
The pre-maturity window is the specific stretch of days before your mortgage matures during which a lender will quote and hold a renewal rate, and its length is set lender by lender.
An Illustrative Example: Locking In 90 Days Before Maturity
This example uses round, hypothetical numbers to show the mechanics only. It is not a rate quote, it does not predict where rates are headed, and it is not financial advice.
Assume an illustrative borrower with a $400,000 mortgage balance, 90 days from maturity. Their lender offers a rate hold with float-down at 5.19%. If the market moves and the same lender’s rate drops to 4.89% before the borrower signs, the float-down clause lets them take the lower number instead.
That is a 0.30 percentage point improvement. As a rough approximation of the annual interest difference on the balance, before amortization effects are factored in:
$400,000 × 0.30% = approximately $1,200 in annual interest, illustrative only.
The actual dollar impact on a real mortgage depends on the amortization schedule, payment frequency, and the exact rates involved, so treat this as a directional illustration, not a calculation you can apply to your own file. A broker can run the real numbers once you have a live quote in hand.
Renewing With Your Current Lender vs Switching During the Hold Window
Holding a rate does not lock you into staying with the same lender. You can use the pre-maturity window to hold a rate with your current lender while also shopping the market, and if another lender offers a better deal, you can switch lenders at renewal instead, generally without a penalty since you are not breaking the mortgage early. If your renewal is coming in noticeably higher than what you were paying, it is also worth reading through your full set of options at a higher renewal rate before you sign anything.
Switching lenders does require requalifying, including income and credit verification, while a straight renewal with your existing lender usually does not. That distinction matters if your financial picture has changed since your last mortgage was set up. Compare both paths before you commit to a hold with either lender.
A rate hold from a second lender is bargaining power, not a commitment, and using it to negotiate with your current lender costs nothing but a bit of paperwork.
Frequently Asked Questions
How early can I lock in my mortgage renewal rate?
Most lenders open a rate hold window somewhere between 30 and 120 days before your maturity date, though the exact number varies by lender. Contact your current lender directly, or ask a broker to check across several lenders, to confirm your specific window.
Does locking in a rate hold cost anything?
No. A rate hold is free and does not obligate you to proceed with that lender or that rate. You can let it expire, switch lenders, or negotiate a better number before you sign the renewal.
What happens if rates drop after I lock my rate hold?
It depends on whether your lender’s hold includes a float-down clause. If it does, you can take the lower rate before signing; if it does not, you are held at the rate you locked unless you ask the lender to requote or you switch lenders instead.
Is it better to renew early or wait until maturity day?
There is no universal answer, it depends on whether your lender offers float-down, how much rate uncertainty you can tolerate, and whether you plan to keep the mortgage for the full new term. Use the decision table above, and speak with a broker who can check float-down availability across lenders before you decide.
Can I hold a rate with a new lender while I’m still with my old one?
Yes. Requesting a rate hold from a competing lender does not commit you to move, and it gives you a real number to bring back to your current lender for negotiation. This is one of the most effective ways to improve your renewal offer.
