Somebody calls me every month with a version of this. They have found the house. An acreage west of Okotoks, an infill in the southwest of Calgary, a place with a view on the edge of High River. The number on the listing starts with a one and a five. And they have twenty percent in their head, because that is the rule everybody knows.
Here's the thing. Twenty percent is the legal minimum above the insured ceiling. It is frequently not enough to make the deal work, and the reason has nothing to do with you. It has to do with where the house sits and how the lender's sliding scale treats that postal code. And on October 26 that scale moved: one major bank raised its Calgary line for houses, which is why Calgary now gets two numbers in this post instead of one.
I have been arranging mortgages in Calgary, Okotoks and the Foothills since 1999. This post walks through the real numbers on a $1.5 million purchase, why they change from one town to the next, what to do about it 90 days before you write an offer, and - because it is the same rule in a different coat - what it means if you already carry a mortgage over a million and it is coming up for renewal. Not a rate anywhere. Just the math.
What does the $1.5 million line actually change?
Mortgage default insurance - CMHC and the two private insurers - is what lets a buyer put down less than twenty percent. Since December 15, 2024, the insured purchase price ceiling has been $1.5 million. The wording matters: the price must be below $1,500,000. Under that line the minimum down payment is 5% of the first $500,000 and 10% of everything above it.
At $1,499,000 the minimum down payment is $124,900. At $1,500,000 - one thousand dollars more - there is no insurance, the floor is 20%, and the minimum becomes $300,000. That is $175,100 of cash you do or do not have to find, decided by where the offer price lands.
Two honest caveats on the insured route. The insurance premium is added to the mortgage, and the qualifying rules under $1.5 million are stricter than most people expect at that size - the income has to carry it on paper at the stress-tested rate, with a 25-year amortization in most cases. It is a real door, but it is a narrow one. The full $1 million-plus page covers that cliff in more detail, including what Americans call a jumbo mortgage and why Canada has no such thing.
So the rest of this post is about a purchase at $1.5 million and up, where there is no insurance and the lender is carrying the whole risk itself. That is where the sliding scale lives.
How much do you need down for $1.5 million in Calgary or Okotoks?
Most A-lenders - the banks, the credit unions, the monoline lenders you have never heard of that fund a large share of Canadian mortgages - do not lend a flat 80% on a high-value home. They lend 80% up to a threshold, and then a smaller share of everything above it. Usually 50%. One monoline goes to 60%. The threshold depends on the lender, and at most lenders it also depends on the town.
For Okotoks, and for Calgary (including Bearspaw and Springbank) at most lenders, the common threshold in the fall of 2026 is $1,250,000. The arithmetic on a $1.5 million purchase looks like this:
- 80% of the first $1,250,000 = $1,000,000
- 50% of the remaining $250,000 = $125,000
- Maximum mortgage: $1,125,000. Down payment required: $375,000, or 25%.
Not 20%. Twenty-five. On the same $1.5 million house, that is $75,000 more cash than the rule-of-thumb buyer walked in with. And this is the top band in Alberta at most lenders - Calgary and Okotoks are treated as well as any market in the province.
New on October 26: one major bank moved its Calgary line. Effective October 26, 2026, one of the big banks raised its 80% threshold for houses in Calgary from $1,250,000 to $1,500,000 (Airdrie and Chestermere moved too). Condos did not change, Okotoks did not change, and most other lenders in Calgary are still at $1,250,000. The arithmetic at that bank on a $1.5 million Calgary house: 80% of $1,500,000 = $1,200,000 of mortgage, $300,000 down, or 20%. For the first time in years, the floor and the answer are the same number - at one lender, in one city, for houses only.
Why does High River need more down than Okotoks?
Take the same $1.5 million house and put it in High River. Twenty minutes down Highway 2. The lender's ladder puts High River, Diamond Valley and most Foothills towns in a lower band, with the 80% threshold at $850,000 instead of $1,250,000.
- 80% of the first $850,000 = $680,000
- 50% of the remaining $650,000 = $325,000
- Maximum mortgage: $1,005,000. Down payment required: $495,000, or 33%.
Go further down the highway to Nanton, Claresholm or Vulcan and the threshold at the two biggest published ladders drops to $500,000, which means a $1.5 million purchase there supports about $900,000 of mortgage and asks for $600,000 down. Here is the whole picture in one table.
| $1.5 million purchase, fall 2026 | Max mortgage | Down payment |
|---|---|---|
| Calgary house (Bearspaw, Springbank included) - one major bank since October 26, 2026 | $1,200,000 | $300,000 (20%) |
| Calgary house - most other lenders | $1,125,000 | $375,000 (25%) |
| Calgary condo apartment | $1,125,000 | $375,000 (25%) |
| Okotoks | $1,125,000 | $375,000 (25%) |
| High River, Diamond Valley, most Foothills towns | $1,005,000 | $495,000 (33%) |
| Nanton, Claresholm, Vulcan | $900,000 | $600,000 (40%) |
Those are the most common published structures on the A-lender side, rounded, on the lesser of the purchase price or the appraised value. Three things move them. One credit union uses a single threshold for the whole province and lands between the Okotoks row and the High River row, at about $450,000 down. One monoline lends 60% rather than 50% on the second band, which on $1.5 million in Okotoks trims the down payment to about $350,000. And an acreage is valued on the house plus five acres, with the scale applied to that number, so the appraisal instruction alone can be worth six figures.
Why does a lender do this? Because it is pricing how fast the house could be resold if it ever had to be. A $1.5 million home in a market with dozens of comparable sales a year is easy to value and easy to sell. The identical home in a town where three properties a decade trade above a million is not. The lender protects itself by lending a smaller share of the top of the price. It is not a judgement on the town. I live in High River. It is arithmetic.
The exceptions at 65%. There are lenders above the lines in that table that will finance 65% of the second band instead of 50%, and a few that use no ladder at all on certain property types. They cost more, and every file is priced on its own. The table is where the conversation starts, not where it ends.
What should a $1.5 million buyer do 90 days out?
The buyers who get this right are the ones who treat the ninety days before an offer as part of the purchase. Four things, in order.
1. Get the deposit ready, separately
The deposit goes in with the offer, in cash, usually within a day or two of acceptance. At this price it is a serious cheque. It is not the down payment - it becomes part of it on closing - but it has to be sitting in an account you can draw on the week you write. If your down payment is in a house you have not sold yet, this is the first place the plan breaks.
2. Build the 90-day paper trail now
Every lender on an uninsured file will ask for ninety days of statements on every account the down payment comes from, and an explanation for any large deposit that shows up in that window. Money moving between your own accounts is fine, as long as both sides are shown. Money arriving from a parent needs a gift letter. Money from the sale of a property needs the statement of adjustments. Start the folder today, not the week the condition is due.
3. Expect an appraisal, and understand what it is appraising
There is no insurer on this file, so the lender orders its own appraisal and lends on the lesser of the price and that number. If the appraisal comes in under the price, the gap is yours. On an acreage, the lender values the house and five acres and applies the scale to that. A sixty-acre parcel with a $1.5 million house on it is not a $1.5 million appraisal in the lender's eyes, and that surprises people every year.
4. Pick the lender before you pick the house
This is the one most people do backwards. Because the threshold depends on the lender and the town, the right lender for an Okotoks purchase may be the wrong lender for High River. A proper pre-approval run through the sliding scales of 30+ lenders tells you the real number before you fall in love with a listing, and holds your rate for up to 120 days while you look. That is the whole point of the ninety days.
And when you have your maximum mortgage, run it through the mortgage payment calculator at a few different amortizations before you fall in love with the kitchen. The payment on $1,125,000 is a number you want to have seen on a screen before you see it on a statement.
Renewing a $1.2 million mortgage? The scale applies to you too
This is the part nobody tells high-value borrowers. The sliding scale is not a purchase rule. It is a lending rule. When your mortgage comes up for renewal and you want to switch to another lender for a better deal, the new lender runs your balance through its own scale on the current value of your home - exactly as if you were buying it today.
Say you owe $1.2 million and the home is now worth $1.7 million. In Okotoks the common scale supports $1,225,000, so the switch fits and you have the whole market to shop. On a Calgary house the same scale gives $1,225,000 at most lenders, and the bank that moved its line on October 26 now supports $1,300,000 (80% of $1,500,000 plus 50% of the $200,000 above it), which is room to spare. In High River the same scale supports $1,105,000, which means the $1.2 million balance does not fit at the lenders with the ladder. Your options there are the 65% lenders, a paydown at renewal, or staying with your current lender - and knowing that before the renewal letter lands is what gives you the leverage to negotiate it.
A $1.2 million mortgage renewing is a high-value file, and your current lender knows that a borrower who believes they cannot switch will sign whatever is in the envelope. The renewal letter is an opening offer. It is not the only one, and at this size the difference between the opening offer and the real one is not small. Call me four to six months out, not four to six days.
Selling a $700K Okotoks home to move up? Count the equity before you count on it
Most $1.5 million buyers in the Foothills are not first-time buyers. They are moving up, and the down payment is sitting inside the house they are leaving. Say you own a $700,000 home in Okotoks with $350,000 left on the mortgage. After selling costs, call the net proceeds roughly $320,000.
Against the Okotoks number above, you are $55,000 short of $375,000. Against the High River number, you are $175,000 short of $495,000. Neither is a reason to stop. Both are a reason to plan. The usual answers are a secured line of credit set up on the current home before it is listed so the deposit is in hand, a firm sale date that lets the lender bridge the gap between closings, a gift from family with the proper letter, or simply a different price point. What does not work is finding out the shortfall the week the financing condition is due.
If you are in Calgary or Okotoks, the top band is working in your favour. Use it. On a Calgary house, the bank that moved its line on October 26 turns that $55,000 shortfall into $20,000 of room, and that is exactly the kind of thing a broker is for. If you are moving to High River, Diamond Valley or further south, the extra down payment is real and it is better found now than in the week of the offer.
The move for this week
If a $1.5 million purchase is anywhere in your next twelve months, do two things. Run the sliding scale for the town you are actually looking in, and get the ninety-day paper trail started. If a mortgage over a million is renewing in the next six months, do one thing: call before you sign the letter. Fifteen minutes, free, and it commits you to nothing.
Three questions I get on this
I have twenty percent down on a $1.5 million house in Okotoks. Why is the lender asking for more?
Because above the insured ceiling most lenders do not lend a flat 80 percent. They lend 80 percent up to a threshold and about half of everything above it. In Okotoks that threshold is $1,250,000, so a $1.5 million purchase supports about $1,125,000 of mortgage and needs about $375,000 down, which is 25 percent. Calgary is different since October 26: one major bank raised its Calgary line for houses to $1,500,000 on October 26, 2026, so there a $1.5 million house can be financed at 80 percent and 20 percent down is enough. Most other lenders in Calgary, and all lenders in Okotoks, are still at 25 percent.
If I write the offer at $1,499,000 instead of $1.5 million, does that really change anything?
Yes, and it is one of the biggest thousand dollars in Canadian real estate. Below $1,500,000 the purchase can be insured, and the minimum down payment is 5 percent of the first $500,000 plus 10 percent of the rest, which is just under $125,000. At $1,500,000 there is no insurance and the floor is $300,000. The insured route carries a premium and stricter qualifying, so it is not free money, but it can be the difference between buying this year and not.
My mortgage is $1.2 million and it renews in the spring. Can I still switch lenders?
Usually, but it depends on the town and the value of your home today, because the new lender runs your balance through its own sliding scale. In Okotoks a $1.2 million balance on a home worth $1.7 million fits at most lenders, and on a Calgary house it fits with room to spare at the bank that moved its line on October 26. In High River the same balance may need a lender that finances 65 percent of the upper band, or a small paydown. Either way, knowing the answer before the renewal letter arrives is what lets you negotiate it.
Buying at $1.5 million, or renewing a mortgage over a million?
Run the real number for your town before you write the offer or sign the letter.
