Mortgage pre-authorization is the step that turns a curious shopper into a serious buyer: a lender has analyzed your file and confirmed a maximum amount and a rate hold for 90 to 120 days (subject to the lender's conditions). In Quebec, the time to get one ranges from 24 hours to 3 weeks depending on the channel — and that gap can cost you an accepted offer if you start too late.
Why pre-authorization timelines vary so much
Three factors explain the spread:
- The channel: in-branch bank, mortgage broker, or direct online platform.
- How complete your file is: an incomplete file bounces back for another round.
- The complexity of your profile: salaried and stable vs self-employed vs variable income.
A simple file (salaried, 5 years on the job, documented down payment, credit score 720+) moves through in 24 to 48 hours via a broker. The same file with 2 years of self-employment can take 4 to 7 days, regardless of the channel.
Real timelines by channel
At a bank branch — 1 to 3 weeks
This is the slowest channel. The advisor has to:
- Collect your documents (often across several appointments or exchanges).
- Submit the file to centralized underwriting (often in another province).
- Wait for the reply — typically 5 to 10 business days.
- Present a posted rate — rarely the negotiated rate.
When it works: if you're already a preferred client of the institution with a simple file (stable salaried income, available down payment, very good credit score). The advisor can sometimes fast-track your file.
The main limitation: you get only one offer — that of this one bank. You don't know if it's the best available in the market.
Through an AMF-licensed mortgage broker — 24 to 72 hours
A broker submits your file to multiple lenders in parallel. Responses generally arrive in:
- A banks (major banks + mono-lines): 24 to 48 hours for a conditional pre-authorization.
- B alternative lenders: 48 to 72 hours (more cautious underwriting on atypical profiles).
- Desjardins caisses: 2 to 5 business days depending on the local caisse.
The broker then presents you with compared offers and their non-rate terms (prepayment privileges, portability, penalties). You choose. All within a week in most cases.
The key difference: you get multiple offers in a single process, with a single credit file inquiry (the credit bureaus group mortgage inquiries pulled within a short window).
Online via a direct platform — 1 to 5 days
Some online lenders offer an algorithmic pre-authorization in hours to days. The process is fully digital — you upload your documents, the algorithm processes.
Upside: speed for simple profiles.
Downside: you only compare a single lender. And algorithmic pre-authorizations are sometimes revised downward at final approval — the algorithm accepts what human underwriting later refuses.
What can drag out the timeline
Whatever the channel, these factors consistently slow things down:
Missing documents — the #1 cause
An incomplete file bounces straight back to you for completion. Each round trip = an extra 24 to 48 hours.
Documents to prepare before starting the process:
| Document | For whom |
|---|---|
| 2 most recent T1s + CRA Notices of Assessment | Everyone |
| 2 most recent pay stubs | Salaried |
| T2125 + 6 months of bank statements | Self-employed |
| Recent employment letter (less than 30 days old) | All salaried employees |
| Current mortgage statement | Renewal / transfer |
| Photo ID (2 pieces) | Everyone |
| 90 days of bank statements (source of down payment) | Everyone |
| Gift letter if down payment is a family gift | If applicable |
Prepare these documents in PDF before starting the process. A broker who receives a complete file submits it the same day.
Self-employed or commission profile
Underwriting analyzes 2 years of T2125s and calculates an average qualifying income. It's not your gross billed revenue — it's declared net income after deductions. Extra time: 24 to 72 hours depending on the lender.
Credit score under 680
Below 680, A lenders run a deeper analysis; some automatically redirect to their alternative team. Below 620, qualification shifts to B lenders — 3 to 7 days, different conditions.

Down payment under 20%
Mortgage insurance (CMHC, Sagen, Canada Guaranty) has to be integrated into the calculation and submitted to the insurer in parallel. This process typically adds 1 to 2 days.
How to shorten the timeline to its minimum
Rule 1: Prepare documents before contacting a broker. Assemble everything in PDF in one folder. A complete file = same-day submission.
Rule 2: Check your credit score upfront. Equifax and TransUnion offer free reports online. If your score is under 660, spend 30 to 60 days rebuilding it before starting (late payments cleared, card utilization ratio brought under 30%).
Rule 3: Choose a broker who submits in parallel. Some brokers contact lenders sequentially — one at a time, waiting for a refusal before moving on. That's not optimal. Ask explicitly whether the broker submits in parallel.
Rule 4: Respond quickly to completion requests. A lender who has issued a conditional offer is waiting for your follow-up documents. Every day of delay = risk that the offer is pulled or that rates shift.
Pre-authorization ≠ funding commitment
This is the most common confusion for first-time buyers. Pre-authorization gives you:
- A maximum amount calculated on your current profile.
- A rate hold for 90 to 120 days (if rates rise, you keep the held rate; if they fall, you can request the new rate — depending on the lender's policy).
- A letter you can show your real estate agent to confirm your seriousness.
What it does not give you:
- Certainty that financing will be granted.
- An analysis of the property you want to buy.
- A commitment on property-specific conditions (value, municipal compliance, title).
Final approval — often called a "funding commitment" or "commitment letter" — comes after your offer is accepted, once the lender can analyze the specific property (appraisal, title, condo status if applicable).
Pre-authorization and the stress test
Every pre-authorization in Quebec integrates the stress test required since 2018: the lender qualifies your file at the contract rate + 2% or 5.25%, whichever is higher. The pre-authorization amount you receive is therefore already the amount you can afford if rates climb 2 points.
That's actually a good thing: pre-authorization with the stress test gives you a realistic price range to shop with, without ending up over-extended at the first rate hike.
Frequently asked questions about mortgage pre-authorization in Quebec
Does pre-authorization affect my credit score?
Each pre-authorization request generates a credit inquiry that can drop your score by 3 to 5 points temporarily. However, the credit bureaus group mortgage inquiries pulled within a 14 to 45-day window — they count as a single inquiry, no matter how many lenders you compare. Run all your comparisons within that window.
What happens if my file changes between pre-authorization and purchase?
The lender re-verifies your file at final approval. If your income has dropped, you've taken on new debt, or your employment has changed, financing may be re-evaluated. Do not take on new debts between pre-authorization and signing at the notary.
Is pre-authorization mandatory in Quebec to make an offer?
No — legally, no one can require it. But in today's market, the vast majority of sellers (and their agents) ask for proof of financing before accepting an offer. Pre-authorization makes you competitive.
Can pre-authorization be renewed or extended?
Yes. If your rate hold expires before you've found a property, most lenders offer a renewal (with a new credit and file check). Let your broker know as soon as the hold is within 30 days of expiry.
