Your credit score is one of the most important factors in your mortgage application. A higher score means better rates, more lender options, and potentially thousands saved over the life of your mortgage. The good news: you can improve it.
How Credit Scores Affect Your Mortgage
Lenders use your credit score to determine risk. Higher score = lower risk = lower interest rate. Here is a simplified view of how credit scores translate to mortgage outcomes:
| Credit Score | Lender Type | Rate Impact | |---|---|---| | 760+ | Best A-lender rates available | Lowest rates | | 680-759 | A-lenders, good rates | Slightly above best | | 620-679 | Some A-lenders, most B-lenders | 0.5-1% higher | | 580-619 | B-lenders, alternative lenders | 1-3% higher | | Below 580 | Private lenders | 3-8% higher |
The difference between a 680 score and a 760 score might only be 0.25%, but on a $500,000 mortgage over 25 years, that is roughly $15,000 in extra interest.
What Makes Up Your Credit Score
Understanding the components helps you target the right improvements:
Payment History (35%)
This is the biggest factor. Even one late payment can drop your score significantly.
Action: Set up automatic minimum payments on all credit accounts. Never miss a payment, even for $20.
Credit Utilization (30%)
This measures how much of your available credit you are using. Using more than 30% of any credit limit hurts your score.
Action: If your credit card limit is $10,000, try to keep your balance below $3,000 at all times — ideally below $1,000.
Credit History Length (15%)
Longer credit history is better. Closing old accounts shortens your average account age.
Action: Keep your oldest credit card open, even if you rarely use it. Put a small recurring charge on it (a streaming subscription) and set it to auto-pay.
Credit Mix (10%)
Having different types of credit (credit card, line of credit, car loan) shows you can manage various debt types.
Action: If you only have credit cards, consider a small line of credit to diversify. Do not take on debt just for score purposes.
New Credit Inquiries (10%)
Each time you apply for credit, a "hard inquiry" appears on your file. Multiple inquiries in a short period can signal financial stress.
Action: Avoid applying for new credit in the 6-12 months before your mortgage application. However, mortgage inquiries within a 14-day window count as a single inquiry.
Quick Wins (30-90 Days)
If you need to improve your score before a mortgage application, focus on these high-impact actions:
1. Pay Down Credit Card Balances
This is the fastest way to improve your score. If you can get utilization below 10% on all cards, you may see a 20-50 point improvement within one billing cycle.
2. Become an Authorized User
If a family member has a long-standing credit card with a good payment history and low utilization, ask to be added as an authorized user. Their account history can boost your score.
3. Dispute Errors on Your Credit Report
Pull your free credit report from Equifax and TransUnion. Look for errors: accounts you do not recognize, late payments that were actually on time, or debts already paid. Disputes can be filed online and resolved in 30-60 days.
4. Set Up Automatic Payments
Ensure every single credit account has at least minimum payment automated. One forgotten $50 payment can undo months of improvement.
Long-Term Strategies (6-12 Months)
Build a Thin File
If you are new to Canada or have limited credit history, open a secured credit card or credit builder loan. Use it for small purchases and pay it in full each month.
Reduce Total Debt
Lower debt-to-income ratios are not directly part of your credit score, but they affect your overall mortgage qualification (GDS/TDS ratios).
Avoid Collections
Even small amounts sent to collections can significantly damage your score. If you have a dispute with a utility or service provider, resolve it before it reaches collections.
What NOT to Do Before Applying for a Mortgage
- Do not close credit cards (reduces available credit, increases utilization)
- Do not open new credit accounts (hard inquiries, lower average age)
- Do not make large unusual purchases on credit
- Do not co-sign loans for others
- Do not change jobs (not credit-related, but lenders check employment stability)
Check Your Score for Free
In Canada, you can check your credit score for free:
- Equifax: equifax.ca (free monthly report)
- TransUnion: transunion.ca (free monthly report)
- Borrowell: borrowell.com (free weekly Equifax score)
- Credit Karma: creditkarma.ca (free weekly TransUnion score)
Checking your own score is a "soft inquiry" and does not affect your score.
