The client
A self-employed professional in Woodstock had her own operating corporation -- not herself personally -- buy a $620,000 live-work commercial-residential unit at 20% down, planning to run her practice from the ground floor and live above it.
Purchase price
$620,000, Woodstock
20% down, corporate purchase
Registered borrower
The professional's own operating corporation
Not the professional personally
Shareholder's own income
$9,200/month
Drawn from the corporation; used to qualify the guarantee
Property carrying costs
$380/mo tax, $140/mo heat
The problem
Because the corporation itself would hold title and be the registered borrower, the lender needed two separate things established before funding -- and neither one could stand in for the other.
Two documents, two different jobs
- ▸A corporate resolution confirming exactly who had authority to sign the mortgage and related security on the corporation's behalf
- ▸The sole shareholder's own personal guarantee -- a secondary, contingent obligation triggered only if the corporation itself defaulted
- ▸Neither document does the other's job: the resolution establishes signing authority, not liability; the guarantee establishes liability, not signing authority
A guarantee is not a joint-and-several covenant, and a corporate resolution is not a promise to repay anything. Getting both documents right, and getting them right for what each one actually does, was the whole file.
The numbers
With the corporate structure and the guarantee both properly documented, qualifying the file itself was a single calculation against the shareholder's own income.
| The corporate purchase | Amount |
|---|---|
| Down payment (20%) | $124,000 |
| Corporate mortgage | $496,000 |
| Total debt service | Figure |
|---|---|
| Qualifying payment (7.05%), 25 years | $3,489/mo |
| Property tax | $380/mo |
| Heat (lender estimate) | $140/mo |
| Total debt service, against the shareholder's income | 43.6% |
43.6% is workable for an uninsured, owner-occupied-adjacent commercial-residential file backed by a personal guarantee, consistent with how average new mortgage amounts and mortgage broker market share data suggest for self-employed, broker-placed files of this size.
The solution
A mortgage agent licensed under Ontario's Mortgage Brokerages, Lenders and Administrators Act made sure the corporate structure and the personal guarantee were each documented for exactly what they were, rather than treated as interchangeable paperwork.
First, had the corporation's directors pass a formal resolution naming the shareholder as the person authorized to execute the mortgage and all related security on the corporation's behalf -- a governance document, not a promise to pay.
Second, had the shareholder separately sign a personal guarantee agreement -- a distinct document creating a secondary, contingent liability, triggered only if the corporation itself defaulted, and materially different from a covenantor's primary, joint-and-several liability on the debt from day one.
Third, confirmed with the lender's solicitor that both documents, not just one, would be required to fund -- avoiding a last-minute scramble had either been assumed unnecessary.
The outcome
The purchase funded at 5.05%, titled to the corporation throughout, with the shareholder's personal guarantee standing behind it and total debt service settling at 43.6%.
Because this is a conventional, uninsured purchase at 20% down, CMHC's ratio maximums do not apply directly; the 43.6% figure is informational.
What to take from this file
- 01A corporate resolution and a personal guarantee do two different jobs. One establishes who can sign for the corporation; the other establishes who is personally liable if the corporation defaults. Neither substitutes for the other.
- 02A personal guarantee is a secondary, contingent obligation, not a covenantor's primary liability. Explain that difference to a shareholder before they sign, so they understand exactly what they are taking on.
- 03Confirm with the lender's solicitor, in writing, exactly which documents are required to fund a corporate purchase. Assuming one document covers what two are actually needed for is an avoidable, last-minute delay.
- 04A self-employed professional's OWN corporation buying property is still a self-employed income file underneath. The corporate structure changes who signs what; it does not change how the shareholder's income is documented.

- ▸Provincial/territorial mortgage-broker legislation fetched directly (bclaws.gov.bc.ca, legisquebec.gouv.qc.ca, fcaa.gov.sk.ca, web2.gov.mb.ca, nslegislature.ca, assembly.nl.ca) plus FCNB's own site for NB and CanLII's index for PE — see notes for per-province method — provincial mortgage regulators and licence titles.
Illustrative in this file — lender-specific, not rules:
- ▸5.05% contract rate — rates move daily; not a quote.
- ▸the shareholder's $9,200/mo income figure — one self-employed professional's own draw from their corporation; not a benchmark for any other practice.
- ▸the TDS figure — this is a conventional, uninsured purchase at 20% down -- there is no CMHC ratio ceiling; the number is informational.
