The two terms get used interchangeably online. They are not the same thing, and the difference shows up the moment you write an offer. Pre-qualification A quick estimate based on numbers you state verbally or through an online form. Nothing is verified, no credit is pulled in most cases, and no rate is held. It is useful for setting an early budget and nothing more. Sellers and their agents give it no weight. Pre-approval A real underwriting exercise. The lender or broker pulls your credit, collects income documents and issues a written commitment for a maximum amount at a held rate — normally for 90 to 120 days. If rates rise inside that window you keep the held rate. If they fall, most lenders float you down before closing.

It involves one hard inquiry, which has a small temporary effect. Mortgage inquiries in a short shopping window are generally treated as a single event by Canadian credit bureaus. How long does a mortgage pre-approval last? Typically 90 to 120 days. After that the rate hold expires and the lender needs updated documents to re-issue it. Can a pre-approval be withdrawn? Yes. It is conditional on your financial position staying unchanged and on the property meeting lender requirements. New debt, a job change or a low appraisal can all void it. Can I get pre-approved with more than one lender? You can, but each is a separate hard inquiry. A broker submits one application and shops it across lenders, which is cleaner for your credit file.
