The client
A self-employed electrician in Alma, sole proprietor operating as Électricité [Nom] enr. — a registered trade name — buying his first home. His contracts, invoices and business bank account all carry the trade name; his T2125, notices of assessment and mortgage application all carry his own legal name, because that is where a sole proprietorship's tax and legal identity always sits.

The problem
An underwriter working the file outside Quebec saw a T2125 filed under one name and a stack of supporting invoices issued under a different one, and treated it as a file with two unreconciled income sources — the kind of underwriting exception that gets escalated rather than resolved — asking, in effect, whose business this actually was and where the rest of the paper trail for the T2125 name was.
There was no second business, and no missing paper trail. A Quebec sole proprietorship simply has no separate legal existence apart from its owner, whatever name appears on the invoice.
What actually links the two names
- ▸Under Quebec's Loi sur la publicité légale des entreprises, a sole proprietor operating under any name other than their own exact legal name must register that trade name with the Registraire des entreprises (REQ), generally within 60 days of starting to use it
- ▸Registration assigns a single Numéro d'entreprise du Québec (NEQ), and the REQ's public register — searchable by anyone — lists both the registered trade name and the owner's own legal name against that one number
- ▸For tax purposes the business was never anything but him: a sole proprietorship's income, whatever name it invoices under, is always reported on the individual owner's own T1 and T2125
His trade name had been properly registered years earlier, exactly as Quebec law requires. The document that actually answers the underwriter's question is not another set of financial statements — it is the REQ's own public extract, which exists in Quebec precisely because trade names and legal names diverge this often.
The numbers
This is an insured purchase at 90% loan-to-value, so CMHC's 39%/44% ceilings apply directly, and the file cleared both comfortably once the name question was resolved and his ordinary two-year average income was accepted at face value.
| The purchase | Amount |
|---|---|
| Purchase price | $275,000 |
| Down payment (10%) | $27,500 |
| Mortgage before premium | $247,500 |
| CMHC premium (3.10% at 90% LTV) | +$7,672 |
| Total insured mortgage | $255,172 |
| Rate and payment | Figure |
|---|---|
| Contract rate, 5-year fixed (illustrative, not a quote) | 4.89% |
| Minimum qualifying rate | 6.89% |
| Monthly payment at the qualifying rate | $1,770 |
| GDS on $5,583/month income | Figure |
|---|---|
| Housing costs (qualifying payment + $180 tax + $95 heat) | $2,045 |
| GDS (no other debt) | 36.6% |
Once the underwriter had the REQ extract confirming one business under two names, there was no further income question left to resolve — the T2125 figures had always been complete.
The solution
A courtier hypothécaire licensed by Quebec's Autorité des marchés financiers treated the name mismatch as a five-minute registry lookup, not a source-of-income investigation.
First, pulled the REQ's public état des renseignements for his NEQ, showing the registered trade name, his own legal name as the sole proprietor, and the registration date — years before either T2125 year in the file.
Second, matched every invoice and bank statement in the file to that single NEQ, confirming there was one business bank account, one set of contracts, and one T2125 — not two overlapping income streams.
Third, included a short note for the underwriting file explaining Quebec's registration regime, since a lender working mostly outside Quebec may never have needed to reconcile a trade name against a legal name this way before — the same kind of jurisdiction-specific context worth building into any self-employed and incorporated borrowers file checklist.
The outcome
The purchase funded at $255,172 (with premium), 90% loan-to-value, on a five-year fixed at 4.89%, qualifying payment $1,770, GDS 36.6% on his full, uncontested two-year average income.
Insured purchase: CMHC's 39% GDS / 44% TDS ceilings apply directly here, both cleared with room to spare.
What to take from this file
- 01A Quebec sole proprietorship has no separate identity from its owner, whatever name it invoices under. A trade name is a marketing choice, not a second business.
- 02The Registraire des entreprises' own register is the document that resolves a trade-name-versus-legal-name mismatch. It is a genuinely Quebec-specific tool — there is no equivalent federal registry for an unincorporated sole proprietor.
- 03Registration is mandatory, not optional, for a trade name other than the owner's own. Quebec's Loi sur la publicité légale des entreprises requires it within 60 days of first using the name.
- 04When a lender outside Quebec flags a name mismatch, lead with the registry, not the financial statements. The financial statements were never actually in question — the identity link was.
