Quick Answer
To qualify for the best rates from major banks (A-lenders) in Alberta, you typically need a credit score of 680 or higher. If you have a down payment of less than 20%, you can qualify for an insured mortgage with a score as low as 600, provided you meet other income and debt-service criteria.
Detailed Explanation
A-Lender Standard (680+): Most "Big Six" banks and local credit unions prefer a score of 680 to offer their lowest advertised rates. Scores between 600 and 679 may still be approved but often come with more scrutiny regarding your employment stability and total debt.
The Insured Minimum (600): For "high-ratio" mortgages (less than 20% down), Canadian insurers like CMHC, Sagen, and Canada Guaranty require at least one borrower to have a minimum score of 600.
B-Lenders and Alternative Options: If your score is between 500 and 600, you will likely need to look at "B-lenders." These institutions generally require a 20% down payment and charge interest rates typically 1%–3% higher than prime, plus additional lender fees.
Impact of the Stress Test: Regardless of your score, you must pass the mortgage stress test. With the Bank of Canada policy rate at 2.25% (as of early 2026), you are typically qualified at your contract rate plus 2%, or 5.25%, whichever is higher.
The $1.5 Million Cap: Effective late 2024, the price cap for insured mortgages (less than 20% down) was increased to $1.5 million. This allows buyers in premium Edmonton neighbourhoods like Glenora or Windermere to enter the market with a smaller down payment than previously required.
30-Year Amortization: First-time homebuyers and those purchasing newly built homes in the Edmonton area can now access 30-year amortizations on insured mortgages. This can help with monthly affordability if your credit score is at the lower end of the qualifying range.
Two Trade Lines: Lenders look for "depth" in your credit history. This usually means having at least two active credit accounts (like a credit card and a car loan) with limits of at least $2,000 each, active for at least two years.
Debt-to-Income Limits: For scores above 600, your Gross Debt Service (GDS) ratio is generally capped at 39% and Total Debt Service (TDS) at 44%. If your score is lower, lenders may tighten these limits significantly.
What to do next
Pull your own reports: Download your reports from both Equifax and TransUnion. In Canada, your score can vary between the two, and lenders may use either or an average of both.
Fix errors immediately: If you find a "late payment" that was actually paid on time, or a cheque that was incorrectly flagged, file a dispute with the credit bureau immediately; it can take 30–60 days to resolve.
Reduce credit utilization: Aim to keep your balances below 30% of your total limit. Paying down a credit card balance is often the fastest way to "bump" a score from a 660 to a 680.
Avoid "Credit Shopping": Do not apply for new car loans, furniture financing, or new credit cards while you are house hunting in St. Albert, Sherwood Park, or Edmonton, as "hard hits" can temporarily lower your score.

Common mistakes to avoid
Closing old accounts: Closing your oldest credit card can lower your score by shortening your credit history. Keep it open, even with a zero balance.
Co-signing for others: If you co-sign a loan for someone else, the full debt amount counts against your own borrowing power in Edmonton, even if you aren't the one making the payments.
Ignoring the "Fine Print" on B-Lending: Many buyers think a B-lender is "just a higher rate." In reality, they often come with a 1%–2% setup fee that is deducted from your mortgage proceeds at the time of closing.
Assuming a "Pre-Approval" is a Guarantee: A pre-approval is usually based on a "soft" look at your credit. If your score drops before the final cheque is issued at the lawyer's office, the lender can pull the funding.
FAQ
Can I buy a house with a 580 credit score? Yes, but usually not with 5% down. You would likely need 20% down and would have to work with a private or B-lender at a significantly higher interest rate.
Does a high credit score get me a better rate? In Canada, the "best" rates are actually often for insured buyers because the government guarantees the loan. However, a score of 720+ ensures you have the most lender options and the lowest non-insured rates.
How long does a bankruptcy stay on my report in Alberta? A first-time bankruptcy generally stays on your Equifax report for 6 years after discharge. Most A-lenders want to see you "discharged" for at least 2 years with re-established credit history.
Will checking my own credit score hurt it? No. Checking your own score (a "soft pull") through apps like Borrowell or Credit Karma does not impact your credit. Only "hard pulls" from lenders during an application affect the number.
Can I use a co-signer to fix a bad score? A co-signer with great credit can help with income qualification, but if your score is below 600, many A-lenders will still decline the file regardless of how good the co-signer’s credit is.
