What Is a Mortgage Pre-Approval?
A mortgage pre-approval is a lender's written commitment to lend you a specific amount at a specific interest rate, subject to verification of the property you're buying. It's different from a pre-qualification:
| Feature | Pre-Qualification | Pre-Approval |
|---|---|---|
| Credit check | No | Yes (hard inquiry) |
| Income verification | Self-reported only | Documents reviewed |
| Rate protection | No | 90–120 days |
| Seller credibility | Low | High — shows you're serious |
| Time required | Minutes | 1–3 business days |
| Used to make offers? | Not recommended | Yes |
In Ontario's competitive market, a pre-approval signals to sellers that you're a serious, qualified buyer. In multiple-offer situations, it can make the difference.
Documents You'll Need
Prepare these before you start. Having them ready speeds up the process significantly:

How Long Does Pre-Approval Take?

Incomplete documents are the #1 cause of delays. Having everything ready upfront is the fastest way to get approved.

How to Maximize Your Pre-Approval Amount
Several factors affect the size of your pre-approval:
- Reduce existing debt: Pay off credit card balances before applying. Monthly debt obligations directly reduce your maximum mortgage qualification.
- Increase your down payment: More down means a smaller mortgage needed. On homes near $1M, 20% down eliminates CMHC insurance and opens additional lender options.
- Add a co-borrower: Adding a co-applicant (spouse, parent) combines incomes and can significantly increase qualification.
- Improve your credit score: Scores above 760 qualify for best rates and maximum amounts. Review your credit report for errors before applying.
- Avoid new debts before applying: Don't finance a car or open new credit accounts in the 6 months before your mortgage application.
Your Rate Hold — 90–120 Days of Protection
A pre-approval holds your rate for 90–120 days. Here's how the rate hold works:
- If rates rise: Your pre-approved rate is protected. You pay the lower rate.
- If rates drop: Most lenders will honour the lower rate at closing.
- If you don't find a home: You can re-apply when the hold expires. No penalty.
- Multiple holds: A broker can hold rates from multiple lenders simultaneously, giving you options without multiple credit inquiries.
Timing tip: Start your pre-approval 1–2 weeks before you begin actively looking at homes. This gives you protection from day one without wasting your hold window.
