Quick answer: A mortgage rate hold is a lender’s promise to keep a rate for you for a set time while you shop, usually up to 120 days. TD and RBC both publish 120 days. If rates rise in that window, you keep the held rate. If they fall, many lenders will move you to the lower one if you ask. A hold is usually free and doesn’t commit you to that lender, but it isn’t a mortgage approval. The rate only counts if your mortgage funds before the hold expires.
Fixed rates can move between one week and the next, even when the Bank of Canada does nothing, because they follow the bond market. Between June 24 and September 23, 2026, the 5-year Government of Canada bond yield that fixed rates follow rose 0.70 percentage points, from 2.99% to 3.69% (Bank of Canada). That’s inside a single 120-day window. If you’re shopping in Ottawa for a few months, a hold means a rate jump during that time doesn’t change your budget.
How does a mortgage rate hold work?
You apply for a pre-approval. The lender checks your income, debts and credit, then issues a letter showing how much you qualify for, at what rate, and until when. That date is your hold.
Two of the big banks spell it out on their own pages. TD says it will hold your rate for 120 days, and that if rates go down in that time you can ask for the lower rate (TD). RBC guarantees the rate for up to 120 days from the application date, and the guarantee expires if the mortgage isn’t funded within that period (RBC). Other lenders set their own periods, so the date on your letter is the one that counts.
Read that RBC detail carefully. The clock usually starts when you apply, not when you find a home, and it has to cover your closing date, not just your offer date. A home you buy in month three with a 60-day closing falls outside a 120-day hold.
What happens if rates go up or down while you’re holding?
If rates rise, you keep the held rate, as long as you close on time and still qualify. That’s the whole point.
If rates fall, the hold doesn’t lock you into the higher rate. Many lenders will reprice you to the lower rate before closing (TD says so on its pre-approval page), but often only if you or your broker ask. Don’t assume it happens on its own.
A hold protects you from a rate increase you haven’t seen yet. It doesn’t get you a better deal than today’s rates. It just means today’s rate is the worst you’ll pay, as long as you close in time.
What does a rate hold actually save you?
Here’s an example on a $550,000 insured mortgage over 25 years. The held rate is 4.54%, the best insured 5-year fixed rate we tracked as of September 30, 2026. The 0.50% rise is hypothetical, to show the arithmetic, not a forecast.
| Rate held at 4.54% | No hold, rates rise to 5.04% | |
|---|---|---|
| Monthly payment | $3,056 | $3,211 |
| Difference | $155 a month, about $9,300 over a 5-year term | |
| Qualifying rate (contract rate + 2%) | 6.54% | 7.04% |
| Monthly payment you must qualify at | $3,697 | $3,866 |
The second half of the table is the part people miss. You’re qualified at the greater of your contract rate plus 2% or 5.25% (CMHC). So a rate rise doesn’t just raise your payment, it shrinks what you can borrow. On the same income, the buyer without a hold in this example would qualify for about $526,000 instead of $550,000. That can be the difference between the house you offered on and the one you can actually afford.
Is a rate hold the same as a mortgage approval?
No. RBC’s own wording is that a pre-approval “is not a guaranteed loan, nor a commitment of financing.” Once you have an accepted offer, the lender still has to verify your documents, review the property (often with an appraisal) and issue a full approval. Your financing condition is what protects you during that step.
The hold also assumes nothing changes. A new car loan, a job change or a drop in your credit score between pre-approval and closing can change the answer. If you’re not sure where your credit stands, see what credit score you need to buy a home in Ottawa.
When doesn’t a rate hold help?
If you won’t buy for six months or more, a hold will expire before you need it. Get pre-approved closer to when you’ll actually shop. If you’re buying a new build that closes a year or more out, a standard hold won’t reach your closing date, so ask about longer options for new construction. A variable rate works differently. What’s held is usually the discount from the lender’s prime rate, so your actual rate still moves when prime does. And a hold from one bank only covers that bank. Holding with a broker lets us move your file to another lender if a better rate or a better fit shows up before you buy.
Common questions about mortgage rate holds
How long does a mortgage rate hold last in Canada?
Usually up to 120 days. TD and RBC both publish 120 days, and other lenders set their own periods. Check the date on your pre-approval letter, and whether the clock started on your application date.
Does a mortgage rate hold cost anything?
Usually not. A standard pre-approval with a rate hold is normally free and doesn’t commit you to that lender.
What if rates drop after I get a rate hold?
Many lenders will give you the lower rate before closing, but you may need to ask. TD’s pre-approval page says you can ask for your rate to be adjusted if rates go down during the hold.
Can I extend a mortgage rate hold?
Sometimes, but don’t count on it. When a hold expires, you usually reapply at the rates on that day. Time your pre-approval so the hold covers your likely closing date.
Does a rate hold mean I’m approved?
No. A pre-approval with a rate hold is conditional. Final approval comes after your offer, once the lender has verified your documents and reviewed the property.
Do I need an accepted offer to get a rate hold?
No. You get it with your pre-approval, before you start looking, which is when it’s most useful.
What should you do next?
If you plan to buy in the next three or four months, get pre-approved now and lock in today’s rate. I’ll find the hold that covers your likely closing date, and if rates fall before you buy, I’ll get you the lower one. Book a 20-minute call with Joshua Tagg.
