How a Mortgage Rate Hold Works in Canada

Short answer: A rate hold locks in today’s mortgage rate for a set period, often up to 120 days, while you shop for a home or get ready to renew. If rates go up, you’re protected. If they go down, most lenders will give you the lower rate. It costs you nothing to have us set one up.

What is a rate hold?

A rate hold (some people call it a rate lock or rate guarantee) is a lender’s promise to give you a specific rate if your mortgage closes or renews within a set window.

Think of it as a safety net. Rates can move a lot in a few weeks. A hold means a jump in the bond market doesn’t shrink your budget or raise your renewal payment before you’ve even signed.

We set up rate holds most often as part of a preapproval for buyers, or a few months before a renewal.

How long does a rate hold last?

It depends on the lender. According to Rates.ca, most lenders offer holds of 30, 45, 60, 90 or 120 days. A few go longer: BMO offers 130 days, and Desjardins sometimes offers up to 180 (Rates.ca).

For most of our clients, the 120 day range is the sweet spot. It lines up with a typical home search, and it lines up with the 4 month window before a renewal.

One important catch: the hold has an end date. If your closing or renewal falls after it, lenders generally won’t extend the guaranteed rate (Rates.ca). If your timeline is long, like a new build, let’s plan for that up front.

What happens if rates rise or fall before closing?

If rates rise, you keep your held rate as long as you close or renew before the hold expires. That’s the whole point.

If rates fall, most lenders will give you the lower rate at closing. The rate they reset you to may not be their best promotional rate, though (Rates.ca). That’s one reason it helps to have a broker watching the market for you. If a better option shows up at another lender, we can move you.

Rates are illustrative and subject to change. A rate hold is not a final approval. You still need to meet the lender’s conditions, like income, down payment and the property itself.

Who should get a rate hold?

• Buyers. If you’re shopping in the next few months, a preapproval with a rate hold tells you what you can afford and protects your budget while you look. If you’re buying in Calgary and want help on the home side too, Tim also works as a Realtor at timlacroix.com.
• Anyone renewing in the next 4 months or so. Your renewal letter isn’t your only option. A hold lets you compare lenders without worrying that rates will run away from you. Our renewal page explains each stage.
• People switching lenders. If you plan to move your mortgage at renewal, a hold with the new lender protects the rate while the paperwork happens.

If your renewal is more than 6 months away, it’s usually too early for a hold, but not too early to plan. Read why your renewal payment could jump and what to do now.

What does a rate hold cost?

It costs you nothing to have us set one up. There’s no commitment either: if you find a home later than planned or your plans change, you’re not locked into anything.

Rates.ca notes that longer holds can come at a price (Rates.ca), so we match the hold length to your actual timeline instead of grabbing the longest one available.

How do I get a rate hold?

It’s simple:

1. Tell us your timeline. When you plan to buy, or your renewal date.
2. Share a few details. Income, down payment or current mortgage balance, and the kind of property.
3. We compare lenders. We look across 50+ lenders for the best fit, not just the lowest number.
4. We put the hold in place. You get the rate and the end date in writing.

What happens if rates go down after I hold a rate?
